Ground-water resources of Cache Valley, Utah and Idaho

This report is based on a study that was designed to provide information to enable the water managers and users in Cache Valley to develop, conserve, and administer their water resources. The report is primarily about the ground water in the valley, but it also includes a discussion of the relation of ground water to surface water and presents a general water-budget analysis for the valley. The report discusses the effects of climate, geology, and development on the source, occurrence, availability, quantity, movement, and chemical quality of the ground water. Most of the discussion pertains to ground water in the Quaternary valley fill, the principal water-bearing unit in the area, but it also includes some information about ground water in other rocks within the Cache Valley drainage basin.
