In 1994, Reclamation continued to support the efforts of the sponsors to develop a <br />cost effective plan, <br /> <br />Lower Gunnison Basin Unit, Colorado <br /> <br />":'-o:!'_ <br /> <br />Reclamation completed a study evaluating alternatives to reduce the cost of the canal and <br />lateral lining, The study found construction costs could be significantly reduced by eliminating <br />the canal lining program, by piping the laterals, and by the continued use of construction <br />cooperative agreements with the water districts. Reclamation has been updating its planning <br />documents to reflect the lower cost estimates and plans, <br /> <br />. <br /> <br />23 <br />
