From The Cortez Journal (Jim Mimiaga):

The Montezuma Valley Irrigation Co. on Tuesday retreated from its boating ban at Narraguinnep Reservoir and agreed to allow some hand-launched, non-motorized watercraft.

The revised ban still includes motorized and trailered boats, including jet skis. Such watercraft can carry water from infected lakes in the engines, bilges and ballasts, according to the MVIC.

The specific list of nine non-motorized boats that are allowed on the lake include kayaks, canoes, rafts, belly boats, windsurfer boards, sailboards, float tubes, inner tubes and paddle boards.

“The board is in agreement on allowing those crafts,” Gerald Koppenhafer, president of the MVIC board, said on Tuesday.

Totten Lake, which is owned by the Dolores Water Conservancy District, also recently banned boating, but is also expected to allow the specific list of non-motorized boats, general manager Mike Preston said on Tuesday.

“The intention of our board is to be consistent with MVI and allow the exempted watercraft,” he said…

The boating ban triggered an outcry from the boating community, and generated complaints to the Montezuma county commission. Dozens of comments for and against the policy were posted on The Journal’s Facebook page.

McPhee Reservoir allows all types of boating, but trailered and motorized watercraft can only enter the lake through two boat inspection stations at the McPhee boat ramp and the House Creek boat ramp. The list of nine, hand-launched boats can launch from anywhere. Funding is available for boat inspection stations at McPhee but not other area lakes.

Irrigation companies and lake managers are trying to prevent the invasive mussel from entering Colorado waterways. Once a lake becomes contaminated with the mussels, they cannot be eliminated and cause damage to irrigation infrastructure, including dams, municipal systems and power plants. Mitigating a mussel contamination year-to-year also dramatically increases operation costs.

A decision is pending on how to prevent a mussel contamination at Groundhog Reservoir, which also is owned by MVIC.

Boating halted at Totten Reservoir, prevention of quagga and zebra infestation cited

Zebra and Quagga Mussels

From The Cortez Journal (Jim Mimiaga):

The Dolores Water Conservancy District board voted unanimously on Thursday to close Totten Lake to all boating to prevent contamination by non-native quagga and zebra mussels…

The Totten closure follows a boating ban on Narraguinnep Reservoir, enacted last week by the privately owned Montezuma Valley Irrigation Co., which also cited the mussel threat.

“To prevent a mussel contamination, and to be consistent with MVIC’s decision, the board voted to prohibit all boating on Totten,” said DWCD general manager Mike Preston.

The boating ban on the two lakes is for all non-motorized and motorized, and includes kayaks, canoes, stand-up boards, windsurfers, oar boats, rafts and jet-skis. Fishing at the popular lake will be allowed from the shore.

“There was a lot of debate on our board about possible exceptions, but the board decided that to be clear, and best protect our irrigators, the ban will be to all boating,” said MVIC manager Brandon Johnson.

A boating closure order for Totten is being drawn up in cooperation with the Colorado Parks and Wildlife, which manages the fishery. A locked gate on the boat ramp will be installed soon. Narraguinnep already has a locked gate installed. Violators at Totten and Narraguinnep will be issued tickets by Parks and Wildlife and the Montezuma County Sheriff’s Office.

Boat inspection stations are effective at preventing a mussel contamination in lakes. But there is no funding for inspection stations at Totten or Narraguinnep, so managers say their only other option is to close them to boating because the contamination risk is too great.

The Dolores Water Conservancy District is also tightening up boating access on McPhee this year to better prevent the mussels from entering the regional irrigation reservoir.

Boating is still allowed at McPhee because there is funding for boat inspections. But access for motorized and trailered watercraft is only allowed during the season through two boat inspection stations at the McPhee and House Creek boat ramps.

When the stations are closed, newly installed locked gates will prevent lake access. In the past, boats could still launch when the inspection stations were closed.

To accommodate boaters who return to the ramps after the boat stations are locked, one-way spike strips will be installed this season to allow boaters to exit the lake after hours.

“We made that concession to prevent boaters from becoming stranded on the lake,” said McPhee engineer Ken Curtis.

McPhee managers adopted the state standard for preventing the mussel that requires trailered and motorized boats to be inspected, but allows non-motorized, hand-launched craft to enter the lake anywhere without inspection.

In general, non-motorized kayaks, canoes, rowboats, stand-up boards, and windsurfers pose less of a risk or contaminating a waterway with mussels.

However, mussels on a boat from an infected lake can be transported to another waterway.

All boats and their motors should be cleaned, drained and dried before entering a waterway and after leaving a waterway.

MVIC also owns Groundhog Reservoir, and is considering closing it to boating. A decision is expected soon.

From The Durango Herald (Jim Mimiaga):

The permanent boating ban went into effect Tuesday, said Brandon Johnson, general manager of the Montezuma Valley Irrigation Co., which owns the reservoir.

“We can’t afford to get the mussel in there because of the damage they cause to our infrastructure,” he said. “We had to take drastic action against this threat because we’re in the irrigation business, not the recreation business.”

Mussels from infected lakes, including Lake Powell, can travel in standing water of boats and contaminate other lakes, clogging pipes, valves and canals.

“If they get in there, we can’t deliver water to our stockholders, costs will increase to mitigate them, and they will get into side rolls and pipes,” Johnson said.

The Narraguinnep ban is for all boats, motorized and non-motorized, and includes jet skis, fishing boats, row boats, kayaks and canoes. Colorado Parks and Wildlife would enforce the ban and issue tickets.

Whether paddle boards and windsurfing would be allowed is not clear. “The board decided on a boating ban,” Johnson said. “Whether those two are boats is up to the enforcement agencies.”

MVIC also owns Groundhog Reservoir and is evaluating whether it will close that lake to boating, Johnson said.

Boating could possibly continue at Narraguinnep if there were a boat inspection program, he said, but the irrigation company cannot afford it.

“Recreation is the responsibility of Colorado Parks and Wildlife,” Johnson said.

Parks and Wildlife operates local boat inspection programs, including for McPhee Reservoir, to check for the mussel and decontaminate boats.

But CPW spokesman Joe Lewandowski said the agency does not have the funding to add more boat inspection programs.

“We’re scrambling for funding for the lakes where we do have inspection stations. They are costly to operate,” he said…

McPhee Reservoir is also restricting access to the lake beginning this year to prevent a mussel contamination. Boat ramps at McPhee and House Creek will be gated, and trailered boats can launch only when boat inspection stations are open.

The McPhee boating restriction does not include hand-launched, non-motorized boats such as canoes, kayaks, rafts, windsurfers and paddle boards. Non-motorized, hand-launched boats are free to launch anytime from anywhere on McPhee. However, all boat owners should make sure to clean, drain and dry all boats before and after entering any waterway to avoid invasive species contamination.

@Northern_Water will revisit boat inspection dough at March 2 meeting

From The Loveland Reporter-Herald (Pamela Johnson):

The board discussed the issue at its Thursday board meeting and will revisit contributing to the $300,000 program at its March 2 meeting.

The inspections are to prevent invasive mussels from getting into the water via boats. If these mussels get into the water, which is used for drinking and agriculture through the region, they can affect aquatic life as well as the infrastructure that stores and moves the water.

Previously, Colorado Parks and Wildlife paid for all the inspections statewide at a cost of $4.5 million, but the agency lost its funding this summer due to a Colorado Supreme Court decision that changed the face of oil and gas severance taxes.

The parks agency is working on legislation for new fees to cover the program as soon as 2018, but the funding for this summer is up in the air.

Stakeholders proposed a three-way split of the total $300,000 cost at the two reservoirs. Larimer County agreed to pay one third from its parks fees, Colorado Parks and Wildlife agreed to pay one third from its reduced budget, and officials with both agencies had hoped Northern Water would kick in the final piece.

After its meeting Thursday, the board released the following statement: “The Northern Water board was briefed … regarding the funding challenges for ongoing boat inspections on the reservoirs associated with the Colorado-Big Thompson Project. Following significant discussion, the board directed staff to continue discussions with the various aquatic nuisance species (ANS) stakeholders. It is likely staff will provide a related resolution and a 2017 ANS funding plan to the board at its March planning and action session.”

Whither the invasive mussel prevention at Green Mountain Reservoir?

Green Mountain Dam via the Bureau of Reclamation

From the Summit Daily News (Kevin Fixler):

It may still be peak ski season, but the time for boating is right around the corner and local officials are at a loss for how to keep up an invasive species prevention program at Green Mountain Reservoir with funding reserves currently bone dry…

Green Mountain, located on the northern end of the county along the Blue River, is considered a relatively high-priority site because of its proximity to the Front Range, and, as a result, large volumes of boaters. It’s why Summit County administrators are ramping up efforts to find financial resources and maintain area boat inspections on the U.S. Bureau of Reclamation-owned reservoir and curb these critters’ arrival…

Green Mountain is much smaller scale, with annual inspection costs that run upwards of $80,000. From 2009-14, the U.S. Forest Service fully funded these watercraft review and decontamination measures based out of the Heeney Marina, but the federal agency was forced to eliminate the program in 2015 due to slashed budgets. Colorado Parks and Wildlife stepped up and paid for the aquatic nuisance species prevention efforts in 2015 and 2016, but recently ran into diminished allocations as well and had to pull out of Summit and focus reserves on only extremely high-risk CPW waters this upcoming summer…

For its part, the Bureau of Reclamation acknowledges awareness of this growing problem, but does not itself conduct or organize recreation or related facilities on the bodies of water it possesses. Instead, it merely authorizes approved activities as managed by partner agencies, such as Larimer County at both Horsetooth Reservoir and Carter Lake in Northern Colorado, and therefore expects those entities to cover these associated costs.

CPW still intends to provide training to staff at Green Mountain’s Heeney Marina in 2017, and do its best to assist with monitoring at a reduced rate. The state agency is also presently in discussions with the Forest Service, as well as other organizations, to see what amount of collaboration might be possible to continue the nuisance species prevention programming in future years.

Meanwhile, at a governmental level, the idea of a bill this legislative cycle requiring a permit in the form of a vessel sticker, say, at a cost of $5 per kayak and $25 per larger boat, has been floated. But as of yet, no one in the General Assembly has stepped up to sponsor such a proposal, even as summer fast approaches.

Inside the Stagecoach Dam: Harnessing the Power — Steamboat Today

Here’s a report from a tour of Stagecoach Dam from Matt Stensland writing for Steamboat Today. Click through for the cool photo of the drain system from inside the dam. Here’s an excerpt:

It is a careful balancing act at the Stagecoach Dam, where electricity is generated for homes, fish habitat is managed and water is stored for a time when cities, ranchers and industry need it.

Behind the steel door, mineralized sludge covers the concrete walls and incandescent bulbs dimly light the narrow corridor.

These are the guts of the Stagecoach Dam southeast of Steamboat Springs, and it can be a little unnerving knowing that at the other side of the wall, 9,360 pounds of pressure push against each square foot of concrete.

Water drips from the ceiling and falls from drain pipes that collect water from the seeping concrete.

“All dams get water into them,” said Kevin McBride, adding that not having a system to drain the water would create pressure and put the dam’s integrity at risk…

“It’s pretty much paradise here,” said Blankenship, who most recently worked at a coal mine and previously worked in the power house of the USS Enterprise for the U.S. Navy.

Rogers has an electrical engineering degree from the Colorado School of Mines.

In addition to monitoring the integrity of the dam, they oversee the hydroelectric power plant, which was named the John Fetcher Power Plant in 1997. He pushed to make electricity generation part of the dam design.

“I think John was a natural conservationist and to have this capability in a project that size and not do it was a bad thing,” said McBride, referring to Fetcher, who died in 2009 at age 97 after being recognized as one of the state’s water leaders.

Above the loud turbine in the power house sits a sign warning people not to stand underneath. That is because above, there is a large, weighted steel lever that will come crashing down if the power generated at the plant needs to immediately come off the grid.

On Tuesday afternoon, the electrical turbine was generating upwards of 500 kilowatts. The system can generate as much as 800 kilowatts, but generation is limited by the amount of water that is flowing into the reservoir.

“The generation, it fluctuates wildly,” said Andi Rossi, the water district’s engineer. “If the flows get too low, we shut down for power generation. In a big wet year, we’ll make a lot of power.”

The water district had been selling the power to Xcel Energy, but Yampa Valley Electric Association began buying the power last year for six cents per kilowatt hour. In 2016, YVEA paid more than $230,000 for the 3.85 million kilowatt hours generated at the dam. That is enough energy to power about 355 homes.

Power generation varies and is dependent on runoff. During the drought year of 2002, only 1.85 million kilowatt hours was produced. When there was abundant snowfall in 2011, 4.7 million kilowatt hours was produced. Since 1999, an average of 3.8 million kilowatt hours has been made each year…

A tower of concrete in the reservoir beside the dam has three gates that allow different temperatures of water to be mixed and sent through a pipe under the dam toward the generator.

From there, the water is either sent through the generator or through a pipe called a jet flow, which shoots water out of the power plant and helps oxygenate the water for fish habitat in the section of river in front of the dam known as the tailwaters.

The area is an angler’s delight and can only be accessed by snowmobile from the Catamount area or by hiking along a county road from Stagecoach State Park.

“It’s phenomenal,” Colorado Park and Wildlife fish biologist Billy Atkinson said.

With improvements by Parks and Wildlife to the river habitat, the area has thrived for fishing, partly because of the dam and reservoir. Relatively warm water released from the dam keeps the section of river from freezing over, and the water from the reservoir is rich in nutrients for the fish.

“The system is very productive,” Atkinson said.

In 2016, 25 percent more people visited the section of river, and 4,000 trout were measured per mile.

Not all tailwaters below dams in Colorado are experiencing similar success.

“It depends on the dam and the operations of the dam,” Atkinson said.

#coleg: @CWCB_DNR hopes to score $25 million for watershed plans @COWaterPlan

Yampa River

From The Denver Post (Bruce Finley):

A Colorado Water Conservation Board proposal, sent to state lawmakers last week, recommends the stream-saving action to meet state environmental and economic goals. It remains unclear who would enforce the community watershed plans.

But there’s little doubt streams statewide are strained by thirsts of a growing population expected to double by 2060, according to state officials. And a Denver Post look at the latest water quality data found that 12,975 miles of streams across Colorado (14 percent of all stream miles) are classified as “impaired” with pollutants exceeding limits set by state regulators.

Creating local watershed plans to save streams is essential, said James Eklund, the CWCB director and architect of the year-old Colorado Water Plan. Eklund pointed to low-snow winters and drought in California’s Sierra Nevada, where 2015 snowpack at 5 percent of average forced a declaration of a state of emergency requiring 25 cuts in urban water use.

“When our Colorado mountain snowpack drops below 60 percent of average, we get nervous. If it happens in the Sierras, it can happen in the Rockies,” he said. “We need to protect certain streams before a crisis. We have got to get on this quickly.”

No single agency oversees waterway health. State natural resources officials monitor flow levels in streams and rivers. They run a program aimed at ensuring sufficient “in-stream flow” so that, even during drought, streams don’t die.

Meanwhile, the Colorado Department of Public Health and Environment sets standards on maximum levels of pollutants that people and companies are allowed to discharge into waterways. In 2015, only 51.6 percent total stream and river miles in Colorado met quality standards, and 30.1 percent of lake surface acres met standards, according to a CDPHE planning document.

“If stream flows are low, there is less dilution in the stream to handle the addition of pollutants through permitted discharges,” CDPHE water quality director Pat Pfaltzgraff said in responses sent by agency spokesman Mark Salley.

Yet CDPHE officials do not make recommendations to natural resources officials about water flows necessary to improve stream health.

The health department has made separate “watershed plans.” CDPHE officials “are considering broadening the division’s watershed plans to include ecosystem health that might be more consistent with stream management plans.”

Pfaltzgraff declined to discuss stream health…

CWCB chairman Russ George supported the push to create local watershed plans, to include detailed maps covering every stream.

“Every stream and tributary needs to be inventoried. … It should have been done a long time ago,” George said in an interview last week.

“We have kind of hit the population and demand place where we have to do it. We didn’t have to do it for the first part of history because the population was small and there wasn’t the impact of all the issues we are getting into now,” he said.

The CWCB voted unanimously last month to ask lawmakers to approve $5 million a year for up to five years to launch local stream planning.

The plans are to be developed within the eight river basin “roundtable” forums that Colorado has relied on for addressing water challenges. These groups draw in residents with interests in stream health who helped hash out the Colorado Water Plan, which was finalized last year and calls for statewide cuts in per person water use by about 1 percent a year.

Conditions along Colorado streams vary, said Bart Miller, healthy rivers program director for Boulder-based Western Resource Advocates. “There are plenty of streams that have problems.”

While state natural resources officials run the program aimed at keeping at least some water in heavily tapped streams, survival in a competitive environment is complex. Leaving water in streams for environmental purposes often depends on timing, when the mountain snowpack that serves as a time-release water tower for the West melts, the amount of snowpack, and needs of cities, pastures and farms.

Collaborative local forums to find flexibility to revive streams “is a great approach.” However, state officials eventually may have to play a central role converting plans into action, Miller said.

“The state should help both in funding the planning but also in implementing the plans,” he said. “We have a lot of work to do. This matters because this is about ‘the Colorado brand.’ Everyone depends on healthy rivers.”

The roundtable forums in communities draw in diverse stakeholders from cattlemen to anglers.

Irrigators and other water users west of Aspen already have created a “stream management plan,” for the Crystal River, seen as a model local effort. Their planning included an assessment of watershed health that found significant degradation above the confluence with the Roaring Fork River. They set a goal of reducing the estimated 433 cubic feet per second of water diverted from the river by adding 10 to 25 cfs during dry times. They’re developing “nondiversion agreements” that would pay irrigators to reduce water use when possible without hurting agriculture, combined with improving ditches and installation of sprinkler systems designed to apply water to crops more efficiently.

Enforcement of plans hasn’t been decided. “We’d like to see more enforcement” of measures to improve stream health, Rocky Mountain Sierra Club director Jim Alexee said. “We definitely think there’s room to do more. We also want to be respectful of the governor’s watershed process.”

Colorado has no history of relying on a central agency to enforce water and land use, CWCB chairman George pointed out.

“When you have a system designed to have everybody at the table, what you’re doing is recognizing there is a finite resource that is shared by everybody. And impacts are shared by everybody statewide. In order to keep from having some force dominate in ways that would not account for all statewide impacts, you need to diffuse the conversation into all areas. That is what roundtables do,” he said.

“When you do that, you’re going to get a better statewide result over time. … It is a process that is designed to get as many interests into the decision-making as you can. … It gets harder, of course, as the supply-demand makes pinches. For the rest of our lives, it is going to be that way.”
