Since this project involves a raw water storage <br />facility, the Board is required to co=ent on the project's impact on existing instream flow <br />water rights and on compacts and/or equitable allocation decrees. <br /> <br />Project Su=ary <br /> <br />Attached is the Project Summary which was prepared by the Authority. The District <br />is proposing to enlarge Fish Creek Reservoir, an existing facility located approximately seven <br />miles east of Steamboat Springs (see attached map). The District contemplates enlarging <br />the reservoir by approximately 2,200 AF. The enlargement will be accomplished by raising <br />the dam and saddle dam approximately 18 feet and constructing a new spillway. The <br />enlarged capacity of the reservoir will be approximately 4,042 AF. <br /> <br />Staff Analysis <br /> <br />The Board has instream flow appropriations on the Middle Fork of Fish Creek for <br />2 cfs and on Granite Creek for 4 cfs. Both streams are tributary to Fish Creek R~servoir <br />and the Board's rights extend to the confluence with the existing reservoir. The Board also <br />holds instream flow rights on the Middle Fork, North Fork and mainstem of Fish Creek <br />downstream from the reservoir. The Board's water rights were decreed in 1977. Based On <br />staff calculations, it appears that the proposed reservoir enlargement will inundate <br />approximately 862 feet of the Board's water right on Granite Creek and approximately 247 <br />feet of the instream flow right on Middle Fork Fish Creek. <br />
