. RESERVOIR WATER auAUTY MONITORING . The U.S. Geological Survey will monitor water quality in the reservoir so that if problems are identified, corrective action in the operation plan can be evaluated. The monitoring wilt be conducted at three sites (near inflow, mid-reservoir, and near dam) on the surface of the reservoir and at two sites (mid- reservoir and near dam) on the bonom of the reservoir. Sampling will be conducted three times each year (May, July, and September) and will include nutrients, major ions, selenium. chlorophyll eo phytoplankton, and trace meta/so Lake profiles of temperature, specific conductance. pH. dissolved oxygen, and secchi disc readings will be done at all sites each visit. Initially, costs for this effort will be about $45,000 annually, with a total cost S392,000 over the life of the study. t COSTS FOR RARE FISH STUDIES AS PART OF THE RECOVERY IMPLEMENTATION PROGRAM . Potential impacts to the endangered fishes of the Colorado River were discussed in the Biological Assessment prepared for this project. It was assumed, and confirmed by the USFWS, that the River District will pay $1 a/acre-foot of depletion for water removed from the Colorado River as per the agreement in the Recovery Implementation Program. The estimated depletion for the Muddy Creek Reservoir project is 7.864 acre feet. This projects to a cost of $78.640. I COST FOR FISH STOCKING IN THE RESERVOIR The River District has agreed to provide the CDOW with funds for annual stocking of the reservoir. This cost has been estimated by CDOW at $10,000 annually. For the so.year life of the project, this could total $500,000. It is possible that a self-sustaining fishery could be established in the reservoir, or that future stocking could be reduced. This would be decided by the River District and CDOW in the future. 34
