Narration

Geology

The dam and outlet works tunnel are founded in limestone, shaley limestone, and quartzose sandstone of the Pennsylvanian Oquirrh Formation. Rock units dip upstream at 30 degrees. Alluvial deposits up to 86 feet deep underlie the shells of the dam and spillway. A positive cutoff was achieved by excavation a cutoff trench through the river alluvium, grouting the foundation rock, and constructing a concrete cutoff wall. The rock was fractured, but no faults were found in the foundation. An additional shallow cutoff trench was excavated beneath the zone 2 downstream of the core to remove a 4-to15-foot-thick sequence of clay and organic material.
