Fish passage begins its work reconnecting Poudre River segments

Construction crews have completed a new fish passage along the Poudre River at Watson Lake State Wildlife Area northwest of Fort Collins.

Built with the cooperation of the participants of the Northern Integrated Supply Project, Colorado Parks and Wildlife, noosa yoghurt and Morning Fresh Dairy, the passage serves to reconnect stretches of river that had been separated by a diversion dam.

Fort Collins company OneFish Engineering designed the project, and the construction company L4 Environmental built it over the past four months.

A dedication ceremony for the new structure is planned for early May. The Poudre Heritage Alliance and Trout Unlimited are also providing assistance, and a public celebration for the new passage is planned during the Pleasant Valley Rendezvous on June 2 at Watson Lake.

Two rapidly-moving strong storm systems, one “bombing out” in the central Plains during mid-week while a second storm intensified over the middle Mississippi Valley during the weekend, brought severe weather and widespread precipitation to many areas of the lower 48 States, including heavy snows to parts of the north-central Rockies, north-central Plains, and western Great Lakes region. In the Northwest, moderate precipitation falling on an unseasonably late (and above-normal) mountain snow pack (due to a minimal melt from a cold spring) produced near- to record high stream flows in much of Oregon and southern Washington. Widespread precipitation, including mountain snows, fell across Idaho, Montana, northeastern Nevada, Utah, and Wyoming. In the Plains, moderate to heavy rains (1-3 inches) were measured in the south-central sections (Oklahoma and Texas), which then moved into the lower Mississippi and Tennessee Valleys (up to 6 inches in northern Louisiana). To the north in colder air, South Dakota was buried under heavy snow (locally over 2 feet). Moderate to heavy snows also blanketed Minnesota, Wisconsin, northern Michigan, and northern Illinois. Meanwhile, light to moderate precipitation was measured in the eastern third of the Nation, with a stripe of heavier rainfall (1.5-3 inches) falling from northern Georgia northeastward into southern New England. In contrast, most of the Southwest, extreme southern, central, and extreme northern Plains saw little or no precipitation. Temperatures generally averaged below-normal in the western two-thirds of the U.S., especially in the northern Plains and upper Midwest (6 to 12 degF), and above-normal in the eastern third of the Nation (6 to 9 degF in the Carolinas)…

High Plains

The mid-week storm system tracked out of the Northwest and into Wyoming, finally dropping decent precipitation (including heavy snow) across much of the state before it moved eastward into South Dakota (up to 26 inches), southern Minnesota (nearly a foot), and central Wisconsin (to 10 inches) by Friday. Liquid equivalents of 1-3.5 inches fell across central Wyoming and much of South Dakota, which was welcome for Wyoming as drier conditions had prevailed there before this week. The storm increased the WYTD basin average precipitation and SWE in Wyoming, with some basins now with WYTD surpluses. Accordingly, a 1-cat improvement was made in central Wyoming where the heaviest totals occurred and WYTD surpluses existed. In northwest Montana, 1-3 inches of precipitation in northwestern Teton, western Ponderosa, and southwestern Glacier Counties was enough to remove D0 as WYTD precipitation and SWE edged above 100% on April 16. Decent precipitation also fell on northwestern Montana (Lincoln County), but longer-term deficits lingered, and D0(L) remained. In Colorado, some scattered precipitation (0.25-1 inches) fell on southern D0 and drought areas, but it was not enough for additional improvements. Drier weather prevailed in Kansas and eastern Nebraska, but that was welcome after wet and cold weather earlier this spring…


Two storm system brought moisture to most of the Pacific Northwest, northern Rockies, and southward into northeastern Nevada and most of Utah. In the Pacific Northwest (mainly Oregon and Washington), this week’s precipitation + late-season snow melt = record high stream flows (flooding), even though WYTD was below-normal in northern areas, and long-term drought (more than 1 year) lingered in some Pacific Northwest areas. Fortunately, reservoirs were filling with the high stream flows, and were expected to rise to normal levels. Accordingly, improvements were made where 12-month SPEIs were normal to wet, precipitation fell this week, and WYTD surpluses existed. Thus, D0 was removed along the southern & eastern edges in Oregon, in central Washington’s Grant & Kittitas Counties, and D1 was shrunk (western edge) in the northern Cascades where 2-5 inches of precipitation fell. In Utah, the same storm system dropped 1-3 inches of precipitation in northern and central Utah, bumping WYTD basin average precipitation to 130-150% and SWE to 150-180% of normal as of April 16. 12-month SPEIs are normal or even wet, thus the western edge of D1 was shrunk and D0 erased thru central Utah. Little or no precipitation fell across the Southwest, but with late winter and spring surplus precipitation, generally below-normal temperatures this year, and mostly WYTD precipitation surpluses, no changes were made in California, Arizona, New Mexico, and Colorado…


With the mid-week (first) storm system mainly impacting areas farther north, the second system that occurred during the weekend developed and rapidly intensified over the southern Plains and lower Mississippi Valley. Widespread moderate to heavy rains (2-4 inches, locally to 6 inches), including numerous reports of severe weather that took several lives, soaked parts of the South, resulting in 1-cat improvements in southwestern and southeastern Oklahoma, northern and central Texas, central Louisiana, and southwestern Mississippi. Arkansas, Tennessee, and northern Mississippi also received abundant rains and remained drought free. In contrast, the rains missed southern sections of Texas and Louisiana, leading to status-quo or some slight D0-D1 expansion. The small D0-D1 area in southwestern Louisiana was shifted southward to better line-up with the driest short-term conditions…

Looking Ahead

During the next 5 days (April 18-22, 2019), another strong storm system will impact the eastern half of the Nation, bringing heavy rains (2-3 inches) and possible severe weather to the Tennessee, Ohio, and lower and middle Mississippi Valleys and the East Coast. Unsettled weather will also impact the Northwest, Rockies, and most of the Plains, although precipitation totals will be much lower. Temperatures will average above-normal across much of the contiguous U.S., with closer to normal readings likely in the Southeast.

The CPC 6-10 day extended range outlook (April 23-27, 2019) favors above-normal precipitation from the Rockies eastward to the Appalachians and in southern and eastern Alaska, with the strongest probabilities over the southern Plains and the lower Mississippi Valley. Below-normal precipitation odds are likely in California. Above normal temperatures are favored for much of the lower 48 States, while Alaska is expected to see below-normal readings.

The Ogallala Water Coordinated Agriculture Project update

From The North Platte Telegraph (George Haws):

The Ogallala Water Coordinated Agriculture Project brings together 70 researchers, along with specialists and students based at seven universities and two USDA research locations…

OWCAP involves research, demonstration and education. The University of Nebraska-Lincoln’s Water Resources Field Laboratory near Brule is one of the research sites.

The TAPS competition at North Platte is also part of OWCAP. TAPS stands for Testing Ag Performance Solutions. A highly respected and innovative program, TAPS is made up of miniature corn and grain sorghum “farms,” where individuals and teams make decisions such as when and how much to irrigate, and how much nitrogen fertilizer to use. Participants earn awards for efficiency and profitability.

UNL water management specialist Daran Rudnick is an active member of the OWCAP research team. He worked with other educators at the West Central Research and Extension Center at North Platte to implement TAPS three years ago.

OWCAP is about identifying and promoting practices that conserve water and prevent water pollution, said OWCAP Manager Amy Kremen, who is also a water expert at Colorado State University.

Sharing ideas is an important part of OWCAP. For example, TAPS is now expanding in coordination with Oklahoma State University to offer a sprinkler-irrigated corn competition at Guymon, Oklahoma, this year.

OWCAP participants in Texas have something to share, too. The Natural Resources Conservation Service and North Plains Groundwater Conservation District there have implemented a master irrigator program that involves intensive training and certification. Now other states are considering implementing similar programs, Paulman said. Programs like that help increase adoption of water conserving practices, he said.

OWCAP has also resulted in research projects that each span three or more states, Kremen said. That “helps us to draw broader conclusions” about the potential of water conservation practices.

Those practices include making effective use of soil moisture sensors and aerial photography to inform irrigation and fertilizer decisions, carefully timing irrigation based on crop growth stages, using university-supported irrigation scheduling tools, and transitioning successfully to dryland…

OWCAP has also resulted in publication of over 50 peer-reviewed journal articles and other reports, which are available at

Kremen said the OWCAP team is on track to complete its USDA-NIFA funded work within the next two years. Team members are the lead organizers for a summit to take place in early 2020 in Amarillo, Texas. There, water management leaders from throughout the region will share their experiences and findings in hopes of benefiting agricultural producers and communities throughout the region.

#Time100: @GretaThunberg

Greta Thunberg via Twitter

From Time Magazine (Emma Gonzalez):

The civil rights movement leaders of the 1960s had no idea that school-shooting survivors from one of the most southern points in the U.S. would lean on their teachings to power a modern nonviolent movement to end gun violence. Students around the world began standing up for their survival, leaning only on the fire inside them to prevent the pain they understand too intimately.

Greta Thunberg saw her power in us, and we in turn see our power in her. Fighting in her home country, Sweden, for a future free from pollution, environmental degradation and climate change, Greta is inspiring steadfast students and shaming apathetic adults.

She realized early on that the powers that be would be stacked against her and her mission, stating, “We can’t save the world by playing by the rules, because the rules have to be changed.” Greta went on to plan a multitude of student protests centered on action against our changing climate. Climate change is our reality, and youth activists like Greta are doing everything within their power to work against it, and demand a change.

González, a graduate of Marjory Stoneman Douglas High School, is a March for Our Lives co-founder.

The City of Thornton files lawsuit over Larimer County’s denial of 1041 permit

From The Fort Collins Coloradoan (Jacy Marmaduke):

Thornton has filed a lawsuit against Larimer County commissioners in protest of their rejection of the Thornton pipeline, kicking off a legal battle on the Poudre River.

The city is asking the Larimer County District Court to overturn the commissioners’ decision and either approve one of the two proposed pipeline routes or force the county to do so.

Thornton’s complaint, filed in the Larimer County District Court on Tuesday night, argues the Board of Commissioners’ decision “exceeds its jurisdiction and/or is contrary to law, misinterprets and misapplies its criteria, and was arbitrary and capricious because its findings lack competent evidence to support the Board’s denial of Thornton’s application.”

In a statement, city spokesman Todd Barnes said Thornton “has taken action to represent the interests and property rights of their constituents.”


Thornton’s water plans wouldn’t diminish flows in the Poudre River because the project’s water is already diverted from the river for agriculture. But the “Poudre River alternative,” which would involve running Thornton’s water down the river and nixing the northern segment of the pipeline, picked up considerable public support during a series of hearings on the project.

“In discussion of Thornton’s proposal during the hearings, it is clear that the Board, contrary to its authority, factored into its decision the notion that Thornton should not build a pipeline but rather send its water down the Cache la Poudre River or down the Larimer County canal,” Thornton wrote in its complaint.
