. . Reclamation on the mechanics of implementing these alternatives. WATER QUALITY Colorado River Basin Salinity Control Forum Salinity Control Forum Work Group Meeting of January 220d and 23ni A summary of the issues discussed is as follows: . Lake Powell Salinity Trends Studies At previous Board meetings I have discussed the work Reclamation has undertaken to identify the potential increase in downstream salinity due to the impact drought conditions is having on reservoir elevations in Lake Powell and Lake Mead. At the Work Group meeting, Reclamation indicated from its investigations, that if the drought should continue, it is theoretically possible that the salinity below Hoover Dam could reach the Forum's numeric value of723 ppm by the end of next year. . Selenium Reclamation also made a presentation on a pilot study on selenium. The pilot study indicates that lining canals and laterals over very shallow soils on Mancos shales, produced approximately 0.1 lb. of selenium reduction per ton of salt reduction. Based on its work, Reclamation estimated that the selenium level in the River might be reduced by 2 ppb for every 400,000 tons of salt reduction. . 2005 Triennial Review Discussion concerning preparation of the 2005 Triennial Report were initiated. The Forum will consider approving the final report at its October 2005 meeting, which will necessitate the Forum to release a draft for public comment by its June 2005 Forum meeting. In order to be able to address the projected salinity levels in the River and the salinity programs ability to meet the numeric criteria, a new salinity model needs to be up and running by June 2004. This issue will be further discussed at the March Work Group Meeting. ~7:z~ Executive Direct 8
