<br />. <br /> <br />Except for the year 200 I, the JPSP has consistently exercised the Martin Cull storage right, filling the <br />reservoir during the winter, spring and early summer months and then discharging the water during the <br />irrigation season. <br /> <br />Project Description and Alternatives <br /> <br />. <br /> <br />The purpose of this project is to provide a means for JPSP to continue to provide irrigation water to it's <br />property situated downstream of the reservoir and dam, Five alternatives have been analyzed in this <br />feasibility study, <br /> <br />L No Action <br /> <br />2, Reconstruct the upstream face of the embankment, line the outlet pipe and replace the inlet <br />structure for the outlet pipe, ($250,000 estimated) <br /> <br />3. Reconstruct the upstream face of the embankment, stabilize the downstream face of the <br />embankment and replace the exiting/damaged outlet structure with a new structure, ($300,000 <br />estimated) <br /> <br />4, Reconstruct the upstream face of the embankment, stabilize the downstream face of the <br />embankment, replace the exiting/damaged outlet structure with a new structure, raise the <br />embankment by 2 to 4 feet and modifY the existing concrete structure in the spillway so that the <br />high water level in the reservoir can be increased by approximately 5 feet, ($330,000 estimated) <br /> <br />5, Complete dam reconstruction, ($1,100,000 estimated) <br /> <br />Alternative No.1 was considered unacceptable since it means the JPSP could not stare provide irrigation <br />water to its property situated downstream of the reservoir and dam, <br /> <br />. <br /> <br />Alternative No.2 was considered unacceptable since the existing embankment was constructed with a very <br />steep downstream embankment slope, which does not meet the current state standards for this type of <br />structure, In addition, the lining of the existing, 50+ year old steel outlet pipe will only prolong the life of <br />the pipe by 10 to 20 years, thus requiring the removal and replacement of the pipe sometime in the future, <br /> <br />Alternative No, 3, which consists of reconstructing the upstream face of the embankment, bringing the <br />downstream face of the embankment to a more stable configuration and replacing the existing outlet <br />structure and pipe with a new structure has been submitted and approved by the State of Colorado - Office <br />of the State Engineer, This is presently the preferred alternative along with the modifications outlined in <br />Alternate No, 4, This alternative will provide the owner with a stable embankment, which should increase <br />the design life of the structure by at least 50 years and allow for the modifications outlined below for <br />Alternative No, 4 to be completed in a timely manner if they are approved by the State Engineer's office, <br /> <br />. <br /> <br />Martin Cull Dam Rehabilitation Feasibility Study <br /> <br />May 2002 <br /> <br />Page 2 <br />
