Reclamation is the lead agency in the Native Fish Work Group, a multi-agency group of scientists attempting to augment the aging stock of endangered razorback suckers inLake Mohave. Larval suckers are captured by hand in and around spawning areas during the . spring and placed into predator-free, lake-side backwaters for rearing through the spring and summer. When the lake is nonnally drawn down during the fall, these fish are harvested from these rearing areas and then released to the lake. The suckers grow very quickly, usually exceeding eight inches in length by September. Senator Wash and Laguna Reservoirs Operations at Senator Wash Reservoir allow regulation of water deliveries to United States water users and Mexico downstream at Imperial Dam. The reservoir is operated to meet . water user demands when necessary and to prevent Colorado River flows from exceeding Mexican Treaty requirements at Morelos Dam. This includes excess flows in the river caused by water user cutbacks and sidewash inflows. Operational objectives at and below Imperial Dam are to meet water user demands, to conserve water, to control sediment, and to maintain the river channel. Releases from Imperial Dam are regulated by Laguna Reservoir to conserve water, to meet all or part of Mexico's water demands, and to maintain river flows downstream. near Yuma. Laguna releases combined with agricultural seepage and drainage provide a continuous live stream serving recreational and fish and wildlife pwposes. Larger releases from Laguna Dam are generally due to excess water from rain, flooding upstream, or from rejected water orders due to rain. These higher releases serve to maintain the river channel capacity. This occasional practice reduces channel maintenance expense without impainnent of water conservation or power production. Yuma Desalting Plant The Yuma Desalting Plant was not operated in 1996, and will not be operated in 1997. Funding is currently not available for full-scale operation. Most of the damage to the Main Outlet Drain (MOD), the Main Outlet Drain Extension (MODE), and the bypass drain from the 1993 Gila River flood has been repaired. Some damage to the MODE near the Gila River confluence will be repaired at a later date. The Wellton-Mohawk Main Conveyance Canal was repaired in 1994. All Wellton-Mohawk Irrigation and Drainage District drainage flows should be diverted into the MODE in 1997. The test train, used for research and the building's water service, will be run throughout 1997. The test train uses about one miI1ion gallons per day of drainage water taken from the MODE or pumped from an on-site well. 13
