The Dam Safety Production Center of the U.S. Army Corps of Engineers is collecting rock core samples in the area around Keystone Dam. USACE geotechnical engineers will use the data to understand the geological features of the soil at depths up to 210 feet.
By collecting rock core samples, USACE engineers can design the project and plan for the construction phase.
The Keystone Dam Safety Modification Project is a dam safety initiative to reduce risk of overtopping from statistically possible storm events. The project is in the pre-construction engineering and design phase, which is expected to last several years.
