Final Feasibility-Level Special Study Report. Odessa Subarea Special Study. Columbia Basin Project, Washington.

摘要

This chapter provides an introduction and background and describes the location, purpose, scope, objectives of the Study, and the Study authority. The Bureau of Reclamation, Washington State Department of Ecology, and Columbia Basin Project (CBP) irrigation districts are conducting the Odessa Subarea Special Study (Study) to investigate the continued phased development of the CBP to replace groundwater currently used for irrigation in the Odessa Ground Water Management Subarea (Odessa Subarea) with CBP surface water. Since the CBP is an authorized project, a special study was done as opposed to a feasibility study; however, analyses were prepared at a feasibility level. This feasibility-level Special Study Report is prepared in compliance with the requirements of the Economic and Environmental Principles and Guidelines for Water and Related Land Resource Implementation Studies (U.S. Water Resources Council, 1983) (P&Gs). The P&Gs represent the main set of project evaluation guidelines for Federal water management agencies. This report presents a discussion of the formulation of alternatives, a description of the alternatives considered, and the results of the P&Gs specific analyses.
