<br />. <br /> <br />. <br /> <br />, <br /> <br />The current proposed project consists of replacing the outlet with an entirely new pipe and adding a e <br />drop inlet spillway in the reservoir capable of passing the 100-year flood. A fuse plug would be placed <br />on the emergency spillway to allow the drop inlet to function without use of the emergency spillway <br />thereby preventing erosion below the dam. <br /> <br />The question of enlarging the emergency spillway would be addressed later at such time as probable <br />maximum precipitation (pMP) estimates for reservoirs above 7,500 feet are available. No expansion of <br />the reservoir is currently proposed. Plans and specifications have been reviewed and approved by the <br />State Engineer's Office. <br /> <br />The total estimated cost of the current proposal is $834,400 including engineering costs and <br />construction. The VRA has spent a total of about $192,000 over the last three or four years for <br />engineering investigations and for breaching the dam. <br /> <br />FEASffiILITY ANALYSES. <br /> <br />The major part of the feasibility analyses summarized in the following paragraphs were conducted by <br />the CWCB staff utilizing technical information provided by Woodward-Clyde Consultants of Denver. <br /> <br />Hydrology and Water Rights <br /> <br />Very basic hydrology and water rights investigations were performed to estimate the physical and legal .. <br />availability of water for the project. Those investigations indicated that adequate water supplies would ,., <br />be available in most years for full exercise of the two Vouga Reservoir storage rights which total 920 <br />acre-feet. The investigation also included the direct flow rights used in conjunction with the reservoir <br />for irrigation of 680 acres ofland owned by the Labrouches. The water rights are summarized below. <br /> <br />Water Rights Summary <br />V ouga Reservoir and Labrouche Property <br /> <br />Name Aoorooriation Date Adiudication Date Decreed Amount <br />Vouga Reservoir 4/20/1955 4/16/1956 510 ac-ft <br />V ouga Reservoir 10/26/1978 12/31/1978 410 ac-ft <br />Anna No. 1 Ditch 5/1/1884 4/29/1904 1.60 cfs <br />Anna NO.2 Ditch 5/1/1884 4/29/1904 0.80 cfs <br />Anna NO.3 Ditch 5/1/1884 4/29/1904 0.80 cfs <br />Anna No. 1 Ditch 5/1/1884 4/19/1943 6.40 cfs <br />Anna NO.2 Ditch 5/1/1884 4/19/1943 3.20 cfs <br />Anna NO.3 Ditch 5/1/1884 4/19/1943 3.20 cfs <br />Ernest V ouga Ditch 6/12/1918 4/16/1956 8.00 cfs <br />Ernest V ouga Pioeline 6/10/1949 4/16/1956 0.16 cfs <br /> <br />2 <br /> <br />e <br />
