Study Activities and Timeline
Basic data and information generally common to storage alternatives will be collected, compiled, and analyzed. This includes: the identification of water supply needs for agriculture,fisheries, and municipal purposes; a determination of the current shortage of water supply to meet these needs; and the availability of water for additional use from the Yakima and Columbia Rivers.
The Storage Study will proceed into the plan formulation process. Potential plan elements for consideration in "future without project"and "future with project" scenarios will be identified in this phase and alternative plans will be formulated, evaluated, and compared. The four storage options to be evaluated, analyzed, and compared against the "future without project" are Black Rock Dam and Reservoir, Bumping Lake Enlargement, Wymer Dam and Reservoir, and Keechelus to Kachess Reservoirs Pipeline. The "future without project" will mainly include water conservation elements. This will identify the extent of water supply needs met if additional storage were not to be developed.
Bumping Lake Enlargement, Wymer Dam and Reservoir, and Keechelus to Kachess Reservoirs Pipeline were identified as alternatives within the Yakima River basin in previous studies.
Viable alternative plan(s) will be selected to carry forward for further analysis into the more detailed feasibility phase. The alternative plan(s) analyzed at the more detailed feasibility level will be included in the Feasibility Report/Environmental Impact Statement. Completion is projected for the fall of 2008.
