Capital construction projects <br />funded and under construction since 1994 <br />and to be funded by proposed legislation <br />The following describes the categories of capital projects under construction and <br />contemplated for the Upper Colorado River Recovery Program and San Juan River <br />Recovery Program. Total construction program cost estimates below reflect capital <br />construction expenditures to -date as well as projected costs for completing all anticipated <br />construction projects. <br />In the Upper Colorado River Recovery Program, construction funding has been provided <br />through Bureau of Reclamation budget line -items since 1994. This is reflected on the <br />"Expenditures to date" sheet in this briefing material, which shows $20.9 million in <br />"Reclamation: Capital ". In addition, certain funds appropriated to the U.S. Fish and <br />Wildlife Service have been expended for capital construction projects. <br />Upper Colorado River Recovery Program <br />Fish passage facilities ($15.1 million) <br />The historical range of endangered Colorado River fish species has been fragmented by <br />construction of diversion dams that block fish migration paths. Fish passage structures <br />around some of these dams would allow endangered fish to access historic habitat, would <br />improve the chances of restoring upstream populations and the likelihood of recovering <br />the fish. <br />A fish passage facility was completed last year at the Redlands Diversion Dam on the <br />Gunnison River in southwest Colorado. Three additional fish passage structures are <br />planned on the Colorado River near Delta, Colo., and one is planned on the Green River <br />near Green River, Utah. Cost estimates for these structures have been based on the actual <br />cost of the Redlands Fish Ladder and on site - specific construction conditions at the <br />proposed sites. <br />Diversion screens ($11.6 million) <br />If found necessary, screens would be installed to prevent adult fish from being diverted <br />from the river into canal systems. These screens also would prevent nonnative fish from <br />re- entering the canals and repopulating these waters. <br />This cost is based on the need to install screens at all fish passage facilities and is based <br />on screening for adult fish only, understanding that some larval fish still may pass <br />through. <br />Yampa River instream flow protection ($31.9 million) <br />The project consists of assessing current and projected flow conditions on the Yampa <br />
