Narration

Geology

The dam, dikes and reservoir are located on unconsolidated glacial, alluvial, and slough deposits in the East Fork of Smith Fork Valley near the Utah-Wyoming border state line. Bedrock was not encountered by drill holes or excavations and is not exposed in the dam area. Postglacial alluvial stream deposits are confined to a narrow strip along East Fork of Smith Fork. The character and thickness of these deposits are unknown, however, physiographic relationships suggest alluvial deposits are thin at both the dam axis and within the reservoir area.
