2 <br />Option 5 - Build a fish ladder similar to one designed by the Corps of <br />Engineers in the mid-1980's. This option was favored by the biologist because <br />it includes fish traps and other options which are necessary for ongoing <br />research. The experts also felt that the design is proven technology which <br />has worked in the northwest and in California. A structure similar to the one <br />proposed by the Corps design was recently completed near Red Bluff in <br />California. The consensus of the experts was to reevaluate the Corps design <br />in light of new technology; trap fish blow the diversion, implant the fish <br />with radio tags, physically move them above the structure, and study the fish. <br />(Studies are planned for FY-93.) If these studies show the fish will use the <br />new habitat, a final design based upon the Corps design could be developed and <br />implemented. <br />Option 6 - Pay Redlands Irrigation Company a power interference fee to stop <br />generating power during the times of fish migration. The diversion structure <br />would also need to be modified to a lesser extent to allow fish passage. The <br />cost of this option has not been fully explored, but it could be expensive <br />because a new pump would need to be installed in the Colorado River below the <br />Gunnison confluence. Water would then be pumped to various points in the <br />Redlands irrigation system. The interference fee, the pump, and the new <br />pipelines may be cost prohibitive. The option may have some adverse impacts <br />on recreation along the Redlands Power canal trail. The Redlands Board did <br />express interest in this option. <br />Option 7 - In the past, the option of purchasing the Redlands power water <br />right and removing the structure has been discussed. A preliminary study <br />found this option to cost about $18,000,000. This option would also require a <br />pump and pipelines to supply Redlands irrigation demands. The option would <br />also severely impact recreational activities along the Redlands Power Canal. <br />List of Experts <br />Bob Strand, Chief, Sedimentation Branch, Bureau of Reclamation. <br />Perry Johnson, Research and Lab Section, Division of Hydropic Structures, <br />Bureau of Reclamation. <br />Charles Listor, Applied Science Branch, Environmental Sciences Section, Bureau <br />of Reclamation. <br />Bob Burdick, Fishery Biologist, Fish and Wildlife Service. <br /> <br />B-2
