Nov 29, 2012 - By Bob Moen, The Associated PressCHEYENNE -- Wyoming conducted more than 38,600 boat inspections this summer under a program that aims to keep undesirable mussels and other invasive species out of the state's lakes and reservoirs.
Only 219 of the total inspections were considered high-risk for possibly having invasive species, and 94 of those resulted in watercraft being decontaminated, said Beth Bear, invasive species program coordinator for the state Game and Fish Department.
No live invasive mussels were found on any of the watercraft that were decontaminated, while four were found to have dead mussels, Bear said.
Nonnative mussels, such as the zebra and quagga, have infected waters in several neighboring states. The mussels can damage native species and ruin fisheries.
The mussels have not been found in Wyoming, and the state began the boat inspection program several years ago in hopes of keeping them out. Boats and their trailers are the most common mode of spreading mussels from one lake to another because the mussels attach themselves to the craft.
Bear said the state monitors lakes and reservoirs considered to be the most likely waters where the mussels might show up.
"So far, so good," she said. "We're still waiting on a few of our monitoring results but by and large everything we've gotten back so far this year, at least for mussels, has been negative."
The state conducted 38,659 boat inspections this year from May 17 through Sept. 9 at 36 different waters in Wyoming.
Jackson Lake in northwest Wyoming had the most inspections with more than 8,500, followed by Flaming Gorge Reservoir with about 3,400, Buffalo Bill with about 3,300, Keyhole with more than 3,200, and Glendo with about 3,100.
