Abstract

This reports evaluates the ground-water resources of about 1,000 square miles in the semiarid uplands south of the Snake River between Bruneau River and Salmon Falls Creek. The outcropping rocks are the Idavada Volcanics of Pliocene age, and the Idaho Group of Pliocene and Plieistocene age, consisting of the Banbury Basalt of middle Pliocene age and overlying predominantly sedimentary deposits of middle Pliocene through middle Pleistocene age. These rocks dip gently northward. The volcanic rocks are the best aquifers, but the yield of water from the sedimentary deposits is adequate for domestic and stock use. About 6,000 acre-feet of water is withdrawn annually from the Idavada Volcanics by 9 irrigation wells to irrigate about 3,000 acres. Only a few tends of acre-feet of water withdrawn from the other formations. The regional dip of the rocks induces weak artesian conditions in the volcanic rocks and somewhat higher artesian head in the sedimentary rocks. Estimated depth to water ranges from less than 250 feet to more than 750 feet, as shown in an accompanying map. The eastern part of the area appears to be more favorable for the development of ground water for irrigation than the western part because of better aquifers at shallower depth.
