Geologic Report for Appraisal Assessment-Wymer Dam and Reservoir; A Component of Yakima River Basin Water Storage Feasibility Study, Washington. Technical Series No. TS-YSS-20
Geologic investigations were perfonned in 2007 to assist engineers in preparing appraisal-level designs and cost estimates for the proposed Wymer dam and reservoir sites. The sites were initially investigated by Reclamation in 1984 and 1985 as part ofthe Yakima River Basin Water Enhancement Project. The earlier investigations focused on an upper damsite, as well as the lower damsite and saddle dike, which are addressed in this report. The 2007 investigation included drilling exploratory drilling at the lower dam and saddle dike sites, and at the proposed pumping plant site near the Yakima River. The investigations were conducted to determine the depth to bedrock, obtain core samples of the bedrock, perform constant-head hydraulic conductivity tests, compile geologic maps, and complete a reconnaissance survey for borrow materials. Exploratory holes drilled on upper left abutments at the dam and saddle dike sites indicated shallow bedrock depths with variable rock quality and permeability characteristics for each of the three bedrock units encountered.
