04:33 PM -- Jackson Gulch Reservoir Project
Gary Kennedy, Superintendent, Mancos Water Conservancy District, discussed the Jackson Gulch Reservoir Rehabilitation Project and aquatic nuisance species study. He distributed a summary of a study comparing the quagga mussel colonization potential in Jackson Gulch Reservoir from September 2008 through March 2009 (Attachment G) and discussed the results of the study. The conclusions from reservoir sampling in 2008 indicated that water-quality conditions were suitable for colonization of zebra and quagga mussels. Sampling in 2009 indicated that Jackson Gulch Reservoir is favorable for mussel colonization during September, but unfavorable during March. He explained that further sampling and characterization is likely needed. He answered questions from the committee about conditions necessary for mussels to survive and discussed measures that could be taken to prevent mussel colonization.
