Should the non-native quaggas infest the [Green Mountain Reservoir], millions in taxpayer money will be spent to ensure they do not clog or damage water infrastructure, as well as to prevent destruction of the aquatic ecosystem and the associated recreational fishing industry.
The danger posed by this critter is so high that Colorado Parks and Wildlife, the U.S. Forest Service, the Bureau of Reclamation, Summit County and other agencies are combining efforts to make sure the quagga does not wind up ruining the reservoir as it has other water bodies in Colorado.
Legislatively, a bill called the “Mussel-Free Colorado Act” dedicated to eradicating quagga and zebra mussels is well on its way to becoming state law. The bill requires boat owners to purchase an aquatic invasive species sticker on top of their regular boat registration to fund mussel prevention measures.
County Commissioner Karn Stiegelmeier has been following developments at the reservoir intently since last August, when the Bureau of Reclamation discovered quagga veliger, or larvae, in the reservoir. At the time, Stiegelmeier said she was furious with the lack of federal funding to pay for boat inspections preventing mussel infestation in the first place.
“Other reservoirs like Dillon Dam and Wolford are taken care of by the responsible dam owners,” Stiegelmeier said. “They pay for regular boat inspections before they get in the water, as they should. But the federal government reservoirs always contract out recreation and claim it’s not their job to making sure boats aren’t contaminated before they launch.”
Federal authorities were put on high alert and finally turned their attention to Green Mountain once mussel larvae was detected. Stiegelmeier said that it will be a much more expensive endeavor to try to ward off infestation after it starts.
“Once a reservoir is infested, the feds wind up having to pay many times as much to deal with the infestation,” she said. “Once the adult mussels get in there you can’t get rid of them. We have a huge number of reservoirs, like Lake Powell, that are infested. It costs an enormous amount of money to get mussels off the dam infrastructure, and it absolutely destroys the aquatic ecosystem.”
While samples at Green Mountain have come back clean since the initial detection, Bill Jackson, head of the U.S. Forest Service’s Dillon Ranger District, said that concern over quagga is far from over…
Jackson said that to prevent the infestation, the Forest Service and other agencies will monitor water at Green Mountain for at least three years — the maximum amount of time quagga need to fully develop. The agencies are also working to divert all incoming boat traffic to a single launch point at Heeney Marina, where they can be centrally inspected and decontaminated before reaching the water. Jackson said that one major risk factor for contamination was how many boats were previously launched from unauthorized areas along the shoreline.
“We had a lot of motorboat launches into the reservoir without proper inspection and decontamination,” Jackson said. “We’ve really been trying to make sure that we got on that right away to prevent folks from doing that.”
Jackson said that the Northern Colorado Water Conservancy District, which gets some of the water from the reservoir, helped in providing rocks, boulders and other implements to block off the known boat entry points. He also said that signage will be put around the reservoir directing boat owners to proper launch points where they will be inspected and decontaminated before hitting the water.
In the months leading to boating season, Jackson said that a major collaborative project will be taking place to improve the inspection and decontamination process at Green Mountain.
The Bureau of Reclamation and other partners will help Heeney Marina to improve its boat launch facilities and parking to accommodate the large amount of boat traffic being funneled there. The Forest Service will do its part by allowing modifications to the marina’s permit for construction there, as it operates on Forest Service land.
The project will also require Summit County to help by closing down and improving the county roads leading into and out of the reservoir, as well as introducing more signage. Details of the project have yet to be released in full to the public, but Jackson said a press release is forthcoming.
Jackson added that they needed the public’s help in preventing contamination.
“If folks are not getting their boats inspected, that doesn’t help anyone, and we wind up dealing with the aftermath of cleanup efforts. Prevention is where we want to be.”
Jackson said that boat owners can help by following a three part procedure: Clean, drain and dry.
