Here’s the release from Colorado Parks and Wildlife (Joe Lewandnowski):
Anglers who participated in the 2019 smallmouth bass tournament at Ridgway State Park, again, helped Colorado Parks and Wildlife on its mission to preserve native fish species.
For the fifth year in a row, licensed anglers caught hundreds of smallmouth bass that are a threat to Colorado’s native fish that live downstream in the Gunnison and Colorado rivers. A total of 79 registered anglers removed 1,498 smallmouth bass in the month-long tournament that ended July 27. Smallmouth bass are non-native and were introduced illegally to Ridgway Reservoir about 10 years ago. They are predators and could wipe out populations of native fish downstream.
“In the five years of the tournament we have reduced the population of smallmouth bass in the reservoir by 79 percent,” said Eric Gardunio, aquatic biologist for CPW in Montrose and the organizer of the tournament. “It is truly amazing what these anglers can do. They are participating directly in wildlife management in Colorado.”
Before the first tournament in 2015, Gardunio estimated there were 3,632 adult smallmouth bass in the reservoir. Adult fish measure six inches in length or more. Now it is estimated that only 763 adult fish live in the reservoir.
“We are making substantial headway in suppressing the population of smallmouth that were introduced illegally to Ridgway Reservoir,” Gardunio said.
The Ridgway tournament targets smallmouth bass because they could escape from the reservoir and migrate downstream to a section of the Gunnison River that is considered “critical habitat” for native fish.
“The work by CPW staff along with the help of anglers shows that through targeted management techniques we can enhance survival of rare aquatic species,” said John Alves, senior aquatic biologist for the Southwest Region for Colorado Parks and Wildlife.
With assistance from the Colorado Water Conservation Board, CPW was able to offer $12,000 in prize money to tournament participants.
Chase Nicholson of Ouray was the big winner this year, catching 571 smallmouth and the top prize of $5,000 for most fish caught. He also won $500 for smallest fish caught – 3.3 inches. Nicholson tied with Tyler Deuschle of Delta for biggest fish caught, 17.2 inches they split the $500 prize. Second place for most fish caught went to Lawrence Cieslewicz of Montrose, who caught 283. He also won the grand-prize raffle for an additional $2,500. Chris Cady from Delta turned in 128 fish and placed third for most fish caught.
The heat of a warming planet, like an artist’s palette knife on a canvas, etches its way across Western forests, slowly altering ecosystems that have flourished for centuries.
Stevens-Rumann, a 33-year-old assistant forestry professor at Colorado State University, was [on site to observe the aftermath of the Spring Fire to measure and mark what comes next. In all likelihood, the ponderosa pine forest that had been there would not return.
Aspen and scrub oak have already sprouted, but all the pine trees and their cones were destroyed. No pine saplings poke through the charred soil.
Across the Rockies and even into the Sierra Nevada and the Pacific Northwest’s Cascades, forests are changing or simply vanishing. Wildfire has played a big role. Insect infestations have also had a hand, as has drought.
Behind it all is one driving force — climate change. Scientists charting the fate of forests see it, whether they are entomologists or botanists or wildfire ecologists like Stevens-Rumann. The heat of a warming planet, like an artist’s palette knife on a canvas, etches its way across Western forests, slowly altering ecosystems that have flourished for centuries.
“We are really moving out of a climate that is suitable for forests,” Stevens-Rumann said. “Old trees can persist, but when change comes in a disturbance like a wildfire and the ecosystem resets, the forests don’t come back.”
The transformation isn’t quite that simple. Lower elevation forests, like those along the Front Range, are most at risk, but as the forest rises into the mountains, the nature of the woods may change with spruce, fir and pine competing for survival even as new pests push into those higher, and now warmer and drier, mountain reaches.
“As ecosystems change, there are going to be winners and losers,” said Thomas Veblen, a biogeographer and distinguished professor at the University of Colorado. “The regulator function of the forest could diminish … leading to more runoff and flash floods. With a reduction of the forest canopy, we are going to see the potential for greater erosion. The question is how much of the forest will fail to regenerate.”
Fire changes the forest’s composition
Colorado’s Front Range has had five ecotones — shifts in plant and animal communities — from grasslands at 5,500 feet above sea level to alpine tundra at 11,300 feet.
“When we go to higher elevations under warming temperatures, we do expect the species from lower elevations to do better after a fire or other disturbance,” Veblen said.
After six years as a forest firefighter in an elite hotshot crew, Stevens-Rumann, curious about what happens after the fire is out, became a wildfire ecologist.
In a study of 1,485 sites that burned in 52 wildfires in forests from Colorado to northern Idaho, a team led by Stevens-Rumann found tree regeneration was significantly reduced at the sites that burned after 2000.
Fewer than half the spots had signs of growing back with a density of trees similar to the pre-fire forest, and nearly one-third of the sites had no trees at all.
These forests ranged from lower elevation dry conifer forests, containing ponderosa pine and Douglas fir, to moister conifer forests of Engelmann spruce and lodgepole pine. The highest elevation forests in the study were around 9,000 feet.
The researchers measured the site temperatures and moisture, and classified the areas by the severity of the burn.
It appeared that the hotter and drier the site, the less chance of a forest coming back. “There is an ecotone shift already underway,” Stevens-Rumann said. “We may see aspen and scrub oak replace pine and at higher elevations, maybe pine replace fir.”
This is happening across the Front Range. An analysis of five Front Range forest fires between 1996 and 2003 — Bobcat Gulch, Overland, High Meadow, Buffalo Creek and Hayman — found that 23% of the forest cover has been lost.
“Below 8,200 feet, we saw little generation; above 8,200 feet, where it tends to be cooler and moister, we saw more,” said Marin Chambers, a researcher at the Colorado Forest Restoration Institute and the study’s lead author.
Savage wildfires disrupt the trees’ lifecycle
At the site of the 2002 Hayman Fire — the largest in the state’s history, consuming 135,114 acres northwest of Colorado Springs — the most intensely burned areas have come back as grasslands.
The problem, Chambers explained, is that while fire releases the seeds of pine cones, they do not travel very far. And the hotter, drier and more open sites where they land are less hospitable.
Fire has been an essential component of the pine forest ecosystem. The pine and fir trees are “serontinous” — depending on fire to release their seeds and simultaneously clear an ashy, nutrient-rich bed for new seedlings.
Two things, however, have altered the natural cycle. First, a century of fire suppression — think Smokey the Bear — has prevented regeneration, creating forests of mostly large, old trees. Additionally, it has built up dead wood on the forest floor that aids fires to burn more intensely when they do happen.
And now those fires are coming more quickly and more savagely. Since 2000, there has been vastly more acreage burned in Colorado than in the three previous decades, with peaks of more than 300,000 acres scorched in 2003 and about 160,000 acres destroyed in 2013.
Across the West, about 20 million acres burned between 1979 and 2015. The average fire season grew by 26 days, a 41% increase, and high-fire-potential days increased by 17, according to a study by John Abatzoglou, a University of Idaho geographer.
Abatzoglou measured drought conditions and water availability, as well as temperature, and estimated that climate change contributed to about half the forest fire acreage as heat parched the forests, creating more dry fuel.
The analysis also found that significant declines in spring rains in the southwestern U.S. during the period from 1979-2015 and in summer precipitation in the Northwest add to the fire problem.
Another Abatzoglou study projects the shortening of the snowpack season except for in the high Rockies and parts of the Uinta and Bighorn ranges in Utah and Wyoming, as well as more precipitation falling as rain rather than snow.
How much hotter has it been? The average observed summer temperature in Colorado between 2005 and 2009 was nearly 67 degrees Fahrenheit — the hottest it has been in a century, up almost 2.5 degrees since 1989, according to the National Oceanic and Atmospheric Administration.
The temperature itself poses an ecological Rubicon. A study of 177 burn sites from 21 forest fires in the northern Rockies documented the same phenomenon Stevens-Rumann saw: fewer trees growing in the lower elevation patches and no trees at about one-third of the sites, with grasses, sedges and a wild, purple evening primrose called fireweed taking root.
The study also calculated that at summer average temperatures above 63 degrees, fir tree regeneration would be “minimal.” Ponderosa pine is slightly more heat tolerant at temperatures up to 66 degrees, the study said…
So much is at stake. And it’s not about the view.
There is much more at stake in the fate of the high-country forests than just a majestic view. The snowpack that falls in the woods, and is essential to nourishing the forest, and it is also the main source of drinking water for the state.
“Every person in Colorado gets a touch of the forest ecosystem every day when they open up the tap,” West said. But thinner forests would lead the dwindling snowpack to run off more quickly.
Even without the spruce beetle, the high-elevation forests are under threat. In a study of Colorado Front Range forests between 9,500 feet and 11,150 feet, researchers found a decrease in new spruce and fir as a result of declining snowpack and rising summer temperatures.
Above-average snowpack was found to be a key in the establishment of new Engelmann spruce and subalpine fir, according to one of Veblen’s studies. Conversely, declining snowpack along with cooler, wetter summers was related to a decrease in the number of fir and spruce establishment events from 1975.
A study of high-elevation areas in Rocky Mountain National Park warned that these ecosystems were “at higher risk of species redistribution as they are more insular and experience more rapid changes than environments at lower elevations.”
In some places, climate change is pushing forests higher or farther. In Alaska’s Noatak National Preserve, boreal forests have moved as much as 300 feet north onto what was formerly treeless tundra.
In Yosemite National Park researchers have found whitebark and lodgepole pines pushing into montane meadows as high at 10,000 feet.
Researchers suggest new approach needed to address Anthropocene risk
A team of international researchers led by Colorado State University is calling for a new approach to understanding environmental risks in the Anthropocene, the current geological age in which humans are a dominant force of change on the planet.
Patrick Keys, a research scientist in the School of Global Environmental Sustainability at CSU, is the lead author of “Anthropocene risk,” a perspective paper published July 22 in Nature Sustainability that suggests adopting a holistic approach to understanding environmental risks. Keys said the team hopes that the article is “productively provocative.”
“The Anthropocene is a time of rapid global change – socially, environmentally, and geophysically,” he said. “Typical notions of neatly and cleanly delineating complex environmental risks are changing in unexpected ways. It’s becoming clear that a more holistic perspective, including social history, power relations, and environmental ethics may be important components of Anthropocene risks.”
As an example, Keys said it’s a common belief that the civil war in Syria has been driven by drought and climate change. While those two factors more than likely played a role in what led to the civil war, it also ignores other aspects such as incentives by Syrian government officials that kept farmers on agriculturally precarious land for decades. Keys said those incentives made it possible for drought and climate change to have such an impact.
“If we ignore the social and political economic factors that deliver us to this present, we will attribute an event to being caused by the environment when, in fact, that was just one cause or the icing on top of the cake. If we look at things only in the present, we will come up with solutions to a problem defined in the present, but we may not be defining the problem correctly.”
This point of view stems from Guidance for Resilience in the Anthropocene: Investments for Development (GRAID), a program based at the Stockholm Resilience Centre, where five of the paper’s co-authors currently work.
In the paper, the research team explores four different cases outside of Europe and North America to highlight this way of looking at environmental risks and underline why people studying such risks must take a broader approach.
“As the Anthropocene unfolds, navigating new and emerging risks will require considering changes that happen over years, decades, centuries, or even millennia.” Keys said. “In this increasingly interconnected and accelerating world, it’s on us to really educate ourselves about how to interact intelligently and meaningfully to work toward a more sustainable world.”
FromThe Associated Press (Felicia Fonseca) via Tucson.com:
That the tiny beetles brought to the U.S. from Asia in an experiment to devour invasive, water-sucking tamarisks showed up at the Verde River in central Arizona is no surprise. But it’s further evidence they’re spreading faster than once anticipated and eventually could pervade the Southwest U.S, raising wildfire risks and allowing less time to uproot the tamarisks, also called salt cedars, and replace them with native trees.
Without those efforts, an already highly flammable tree will burn more intensely, and an endangered songbird that nests in tamarisk might not have a home.
The federal program to use the beetles to chew up tamarisk trees began as an experiment in rural Nevada in 2001 and was approved for more widespread use in 2005, as long as they were at least 200 milesfrom Southwestern willow flycatcher territory. It ended in 2010 as the beetles intruded on the birds’ habitat. An unintentional release in southern Utah also helped the insects spread into Arizona.
Johnson believes the quarter-inch beetles hitchhiked to the Verde River on clothing, a backpack or a boat. Normally, they are wind travelers but would have had to catch quite a gust to get to the river from the closest drainage where they’ve been recorded, he said.
Johnson has sent samples to a geneticist in Colorado to determine if the beetles can be traced to a population north of Arizona or a subtropical one from Texas that multiplies quicker.
Arizona once was projected to be too hot for the beetles to survive, but they’ve evolved as they’ve expanded their reach.
Dan Bean with the Colorado Department of Agriculture found even more this summer in far southwestern Arizona along the California border, where temperatures regularly top 100 degrees.
The concern now is the beetles establishing themselves in the Gila, Salt and San Pedro watersheds, which have higher concentrations of flycatcher habitat.
The beetles aren’t known to feast on anything other than tamarisks, though one beetle can’t eat much on its own. In the thousands, they can consume entire trees, Bean said.
The tamarisk leaves can grow back within the season, but repeated attacks can be fatal for the trees — a welcome result in places flycatchers don’t live.
Dead tamarisks can litter the ground with leaves and increase wildfire risks.
The trees already are notorious for burning hot and black, and beetle predation would provide more fuel.
Ben Bloodworth works with Rivers Edge West, formerly the Tamarisk Coalition, which has been tracking the beetles’ movement for years.
The group has mapped the beetles along the Green River in Utah, the Rio Grande and Pecos River in New Mexico and Texas, the Arkansas River in Colorado, the Colorado River — a major source of water for 40 million people in seven Western states — and other waterways.
“Eventually the beetles will be throughout the entire Southwest, and really what we need to do is, in areas where it’s appropriate, get in ahead of the beetle (and) plant willows and cottonwoods and other native species that can provide habitat for the willow flycatcher,” Bloodworth said.
The beetles and the songbird have been the subject of legal fights. The Tucson-based Center for Biological Diversity sued the U.S. Department of Agriculture and its Animal and Plant Health Inspection Service in 2013.
The lawsuit alleged the damage caused by the insects through the beetle release program violated the Endangered Species Act, and argued the federal government should be held liable.
As part of a settlement, the USDA released a draft conservation plan in June for the flycatcher, which is found in parts of Arizona, California, Colorado, Nevada, New Mexico, Texas and Utah. Under the plan, the agency would aid existing conservation programs, contribute money and monitor beetle impacts. The public has until Aug. 8 to weigh in.
The beetles would not be in the United States if not for the tamarisk that thrives along riverbeds.
As confirmed cases of invasive mussel contamination on out-of-state boats reach record numbers in areas close to Boulder County, local authorities say the problematic species’ profile remains low, as it traditionally has, within county borders.
Reservoirs popular with recreational users in Boulder County have policies governing what boaters have to do before putting in, efforts to decontaminate all crafts entering local waters and biology to thank for the good news…
At Longmont’s Union Reservoir, inspectors in the past 10 years have come across only two vessels contaminated with invasive mussels, and so far, none have been found this year, according to John Brim, a city parks and open space ranger.
Because only wakeless boating is allowed at Union Reservoir, it doesn’t attract boats used most often at out-of-state bodies of water known to harbor the invasive species; Lake Powell is especially notorious…
At Boulder Reservoir, cases of contaminated boats are slightly more common, with one confirmed contamination this year, and about five suspected mussel contaminations, with several of those confirmed, since 2008, according to Boulder Reservoir Manager Stacy Cole…
Between 15 and 20 decontaminations have taken place this year in Boulder, including one Monday, for boats that haven’t received a permit tag from the city or those that have and since were used on an out-of-state waterway.
“Parks and Recreation staff use a mobile decontamination unit which flushes the system including ballast tanks with high-temperature water — 140 degrees Fahrenheit — necessary to kill mussels,” Boulder spokesperson Denise White said. “The city also adds potassium hydroxide to the decontamination water to kill any possible mussels before the wastewater enters the city’s sanitary sewer system.”
Boulder boosted its precautions for this year, requiring not only an initial decontamination process for untagged boats and those coming in after a stint outside Colorado, but also an ensuing seven-day quarantine period on dry land at Boulder Reservoir and a second decontamination before the vessel is allowed back in the water. Cole said there was no particular incident that prompted the city’s move. Rather, the growing number of mussel-infested waterways in surrounding states has prompted such prevention initiatives across the state, she said…
Boaters can receive their first decontamination for free from state officials in Denver, and then pay Boulder for their second decontamination at rates that vary from $35 to $175 depending on the size of the watercraft…
Broomfield protects itself from the pesky organism by disallowing boating on all its waterways.
Here’s the release from Colorado Parks & Wildlife (Joe Lewandowski):
The number of boats infected with mussels intercepted in Colorado by inspectors in 2019 is already even with the total from last year – and we’re only halfway through the boating season.
“I am just being completely over-run by mussel infested boats,” said Robert Walters, CPW’s assistant manager for the aquatic nuisance species program. “We are already up to 51 interceptions this year. We are having interceptions just about every day at waters throughout the state. And most of the boats are coming out of Lake Powell.”
Colorado Parks and Wildlife is warning boaters that they must clean, drain, dry and disinfect their boats before traveling to any reservoir in Colorado, especially when boats are brought in from out-of-state. Boats coming in from heavily infested Lake Powell are especially problematic. While boats are supposed to be inspected as they leave the desert impoundment, inspection stations there are overwhelmed and not all boats are thoroughly inspected. Mussels have even been found on paddleboards and canoes that have been in Lake Powel.
All boats that are not previously “sealed” at Colorado reservoirs receive a thorough inspection and engine flush at inspection stations. Any boats found with mussels must be completely decontaminated, a process that can last a week or more.
Colorado’s reservoirs are mussel free and the state and cooperating agencies operate a robust inspection program. But if an infestation occurs, it could be devastating for reservoirs and water-based recreation.
The number of boats infected with mussels is increasing. In 2018, 51 boats with adult mussels were found at inspection stations, far more than the previous record of 26 boats in one year. Since the ANS program started in Colorado in 2008, CPW staff and other entities have completed nearly 4.5 million boat inspections, more than 90,000 boats have been subject to decontamination procedures and more than 200 vessels with confirmed mussel infestations have been intercepted and decontaminated.
Mussel infestations cause a variety of major problems. Because mussels consume plankton, they disrupt the food web and out-compete sport fish and native fish. Mussels clog infrastructure, including reservoir dams, outlet structures and distribution systems that carry water for irrigation, municipal and industrial uses. Mussels also infest boats and damage engines.
Mussels have caused billions of dollars in damage, especially in the upper Midwest and Lower Colorado River. Nearby states where mussel infestations exist, include Utah, Arizona, Kansas, Nebraska, Texas and Oklahoma.
Kirstin Copeland, manager at Ridgway State Park, explained that the companies and organizations that own most of Colorado’s reservoirs could shut down all water-based recreation.
“They are concerned about potential damage to their infrastructure,” Copeland said. “They could say no to all boating.”
All boat owners who have been to Lake Powell should take extra care to inspect every inch of their craft and trailer – including lines, anchors, seat cushions, live wells and paddle craft. Owners can also call CPW if they have questions about the aquatic nuisance program and inspections.
Range fires get bigger every year, threatening sagebrush habitat and rural towns.
Between the town of Elko, Nevada, and the Idaho border stretches some of the most remote land in the Lower 48, rolling hills and arid basins as far as the eye can see. Last July, this section of the Owyhee Desert was scorched by a fierce, fast-moving blaze with 40-foot flames, the largest wildfire in state history. In the end, the Martin Fire burned 435,000 acres, including some of the West’s finest sagebrush habitat. Now, the raw range wind whips up the bare earth into enormous black clouds that roil on the horizon.
Once rare, fires that large, hot and destructive are now common in the Great Basin, a 200,000-square-mile region of mountains and valleys that includes all of Nevada and much of Utah, as well as parts of California, Idaho and Oregon. But despite the rising fire risk, a general lack of attention is putting the rangeland in growing danger.
The fire problem “risks permanent loss” of the ecosystem, according to Jolie Pollet, a fire ecologist and the Bureau of Land Management’s division chief for fire planning and fuels management. This is a genuine crisis, she said, and it demands greater urgency and attention than it is currently getting.
“The general public, especially urban areas, doesn’t seem to have an appreciation for the impacts on these landscapes, since the areas are so sparsely populated,” she said.
The new ferocity of rangeland fires has an old culprit: cheatgrass, an annual originally from Eurasia that was brought to this country in cattle feed, packing material and ships’ ballast in the late 1800s. It has since proliferated through overgrazing and development. The grass burns easily and often, and it thrives on fire. In intense blazes, when native shrubs perish, cheatgrass simply drops its seeds and then expands into the burned areas. The areas of greatest fire risk in the Great Basin have a high correlation with the areas of highest cheatgrass incursion, and the increasingly dry and arid climate brought by climate change is encouraging its spread. The Great Basin now has the nation’s highest wildfire risk.
Historically, sagebrush habitat burned about once every century or less, but now it happens around every five to 10 years. Over the past two decades, more than 15 million acres of sagebrush have been permanently lost to fire, according to the BLM, 9 million of them since 2014. Overall, since 2000, more acres of shrubland or grasssland have burned than forest.
If sagebrush decline continues, the approximately 350 species that depend on it are in serious trouble. The Martin Fire burned some of the best sage grouse habitat in the country and destroyed more than 35 grouse mating grounds, or leks. The fires also harm watersheds, cause erosion and destroy wildlife corridors used by pronghorn antelope, mule deer and elk.
The impact on rural Americans is equally severe. Counties and ranchers must deal with infrastructure loss, including troughs, fencing, and damage to roads and powerlines. Many ranchers struggle with the additional costs, said Ron Cerri, a rancher and commissioner in agriculture-dependent Humboldt County, where the Martin Fire burned. Ranchers may lose hayfields in a blaze, for example, and six months of hay for 500 cattle costs about $216,000, according to Cerri. Cattle often die in the flames, and ranchers have to put down animals crippled by the smoke. Jon Griggs, a Nevada rancher whose land burned in 2007, called it the worst part of the job.
Because sagebrush ecosystems are neglected, they get less funding, making the fire threat even worse. Indeed, the BLM receives even less money than the already-underfunded Forest Service. For 2019, the Forest Service got about $400 million in annual funding for fuel management, and about $1.3 billion for firefighting preparedness. The BLM received $85 million and $180 million respectively, even though it manages about 50 million more acres of public land. The BLM also received $11 million for fire recovery, a microscopic amount, given the scale of the problem.
When the BLM runs out of firefighting money, it’s forced to raid other programs, as the blazes quickly burn through agency budgets.
“The agencies run out of money and all the other programs get gutted,” said University of Montana wildlife biology professor Dave Naugle. “In the long term, it really hurts conservation.”
Last year, Congress passed a measure that allows the BLM to access emergency fire funds without draining other initiatives. But the provision doesn’t kick in until next year, and even when it does, the BLM will remain seriously underfunded for firefighting, prevention and restoration.
Meanwhile, wildfires are already burning across the West, and the cheatgrass is beginning to dry up, turning from its spring purple to the yellowish hue that signals its readiness to burn.
Pollet put it succinctly: “I’m scared for 2019.”

Here’s the release from Colorado Parks and Wildlife (Mike Porras):
The illegal, unapproved relocation of fish from one body of water to another continues to cause significant problems for management agencies, water providers and ethical anglers across Colorado.
Recently joining the list of reservoirs impacted by the presence of illegally introduced northern pike is northwest Colorado’s Kenney Reservoir. In the fall of 2018, Colorado Parks and Wildlife aquatic biologists confirmed the presence of the nonnative predator in the estimated 335-surface-acre reservoir located near the town of Rangely. Authorities believe the northern pike were most likely dumped illegally into the reservoir, or the White River, by a ‘bucket biologist,’ a pejorative term used to describe someone that moves live fish in an effort to create their own personal, unapproved fishery.
“Releasing fish unlawfully and selfishly is self-defeating and will not work as intended,” said Lori Martin, CPW’s Northwest Region senior aquatic biologist. “Because northern pike are indiscriminate predators and consume any fish they catch, we will not throw our hands in the air and ignore the problem. We will take action one way or another to deal with this illegal introduction because it is very harmful and the stakes are so high. This hurt existing fisheries and it certainly has negative impacts on anglers, the majority of whom are law-abiding and ethical.”
CPW says illegal fish stocking can result in fines up to $5,000 and the permanent loss of hunting and fishing privileges. In addition, anyone convicted of illegal fish dumping will likely have to pay up to hundreds of thousands of dollars to reclaim the body of water.
The presence of northern pike has prompted CPW and reservoir owner Rio Blanco Water Conservancy District and other partners, including the Town of Rangely, Rangely Area Chamber of Commerce, Upper Colorado River Endangered Fish Recovery Program and the Colorado Water Conservation Board, to initiate an angler harvest incentive targeting all northern pike found within the District’s boundaries. Beginning June 1 and continuing through Nov. 30, licensed anglers can earn $20 for each northern pike caught and removed from Kenney Reservoir, the White River and other waters, from approximately Stedman Mesa to the Utah border.
Kenney Reservoir is very popular with anglers and currently recognized as an excellent channel catfish, black crappie and common carp fishery. In addition, CPW stocks rainbow trout annually at the expense of the State of Colorado; however, due to the presence of northern pike, Martin says the agency will have little choice but to cancel the remaining catchable trout plants in Kenney Reservoir in 2019. She says until the issue is resolved, she is not sure when they can resume stocking.
“Moving any live fish is a criminal act and can cause great damage to an existing fishery, threaten our native fishes and cost the sportsmen and women of Colorado thousands of dollars annually,” said CPW’s Area Wildlife Manager Bill de Vergie of Meeker. “We would prefer to dedicate our time and sportsmen’s dollars on other projects that directly benefit the angling public, rather than spend money and manpower on fish removal efforts.”
Research conducted by partners in the Upper Colorado River Endangered Fish Recovery Program has shown that the unapproved presence of nonnative predators like northern pike and smallmouth bass in critical, native fish habitat is among the most significant impediments to the recovery of Colorado’s endangered fishes – Colorado pikeminnow, humpback chub, bonytail and razorback sucker. The rare species exist nowhere else in the world except in the Upper Colorado River Basin.
According to the U.S. Fish and Wildlife Service, the White River, upstream to the Rio Blanco Lake dam west of Meeker and downstream of Kenney Reservoir, is designated critical habitat for the Colorado pikeminnow, and the lower 18 miles of the White River in Utah is designated as critical habitat for razorback sucker. Smallmouth bass, northern pike and other nonnative species in these river stretches have proven detrimental to native fishes.
Other Northwest Region reservoirs dealing with the repercussions of unlawful stocking of northern pike include Green Mountain Reservoir and Wolford Mountain Reservoir. CPW and the Colorado River Water Conservation District initiated angler harvest incentives at both reservoirs several years ago, similar to the one planned at Kenney Reservoir. Licensed anglers can earn $20 for each northern pike caught and removed.
To participate in the angler harvest incentive within the Rio Blanco Water Conservancy District’s boundaries, anglers should bring their freshly caught northern pike to the District office at 2252 East Main Street in Rangely during typical business hours, 7 a.m.- 4 p.m. Monday – Thursday, and 7 a.m.- 3 p.m. on Friday. The District will administer the cash harvest incentive with funds provided by CPW through a Colorado legislative bill that appropriates severance tax dollars to the Species Conservation Trust Fund.
To collect CPW’s angler harvest incentive at Green Mountain Reservoir, anglers can bring freshly caught northern pike to the Heeney Marina during business hours. Call 970-724-9441 for more information. To collect the Colorado River Water Conservation District’s angler harvest incentive at Wolford Mountain Reservoir, take the freshly caught northern pike to the campground host, or call 970-724-1266.
For each body of water, anglers must present their fishing license to qualify for the harvest incentive.
“Our removal efforts thus far have been effective at reducing the number of northern pike in Kenney and we believe the population is still relatively small,” said Martin. “But northern pike are prolific and it doesn’t take long for a small population to grow, especially if no management action is taken. We encourage anglers to participate and help us eliminate northern pike from Kenney and the surrounding area. If the pike population continues to grow, we may have to resort to less palatable options for managing against northern pike in the future.”
For more information about the angler harvest incentives contact CPW Northwest Region Senior Aquatic Biologist Lori Martin at 970-255-6186.

On May 1 state officials kicked off the summer boating season in Grand County with the opening of the Stillwater Boat Ramp on Lake Granby. Since then several other boat ramps across Grand County have been opened to the public. According to information from Elizabeth Brown, invasive species coordinator for Colorado Parks and Wildlife, the Grand Lake Boat Ramp was opened May 17 along with the Sunset Boat Ramp on Lake Granby and the Green Ridge Boat Ramp on Shadow Mountain Reservoir…
Historically boaters were able to launch boats onto the waters of Grand County any time of year, even when boat inspectors were not present. However, beginning in 2018, federal officials began requiring that all boat ramps leading onto the waters of Grand County remain locked whenever boat inspectors are not present.
The boat inspection program is part of an invasive species prevention program operated by Colorado Parks and Wildlife. The program is primarily focused on preventing the establishment of quagga and zebra mussels, both of which are invasive species, in the waters of Colorado. Brown confirmed that currently no waters in Colorado are infested with either of the small bivalves. In 2017 12 juvenile quagga mussels were found in Green Mountain Reservoir. According to Brown additional searches were conducted that year that revealed no additional mussels. Follow up testing of the reservoir over the past year has yielded no additional mussels.
A private business, Rocky Mountain Recreation, is contracted by the state each year to provide boat inspectors in Grand County. That contract alone, which does not include any personnel costs derived from state or federal employees, is $468,000. That tally includes the cost of inspections at Williams Fork Reservoir along with inspections on the Three Lakes. Statewide the total program is roughly $4.5 million…
According to Brown there were 3,084 inspections conducted on Grand Lake last year, 4,500 on Shadow Mountain Reservoir and 12,600 on Lake Granby. That figure includes boats that were inspected on their way into the lakes and on their way out as well.
