~J tion rate. Delivering project water directly to Roberts Tunnel via pipelines would be a possible mitigation measure. The cost of this type of mitigation would range from $35 to $40 million. Impacts to Tenmile Creek could be eliminated with direct discharge into Dillon Reservoir. Aquatic Life. The Eagle-Piney/Eagle-Colorado project would provide an opportunity for increased access to streams in areas that are now remote and/or inaccessible. Increases in fishing pressure would also result on those streams. The Colorado River cutthroat trout populations in these streams may be susceptible to overharvesting by construction workers and by sport fisherman who would take advantage of project-related access. The Colorado River cutthroat trout is a candi- date for the Federal endangered species list and is also a species of special concern to the State of Colorado. The potential short-term snd long-term adverse impact could be reduced by implementing rest ricted fishing regulations on the streams that provide key habitat for the fish species in the study area. A supplemental fish stocking program, costing $10,000 to $20,000 annually, could also ba implemented. Wetlands and Riparian Areaa. Approximately 750 acres of the total wetland acreage in the study area would be significantly affected by the project. The reservoir would inundate about 400 acres of wetlands. In addition, approximately 200 acres would be directly affected by construction and placement of other project facilities. Water diver- sions would remove either the primary or all water sources for approxi- mately ISO acres of wetlands located downstream from the project's diversion points. Where facility operational adjustments could miti- gate wetland.s impacts, the cost could be approximately $100 per acre per year. When new wetland creation would be the requi red form of mitigation, the costs could range from $5,000 to $10,000 per acre, depending on local factors. 26
