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.
U.S. Army Corps of Engineers (USACE), Seattle District is actively monitoring the widespread navigation hazards caused by the recent accumulation of large woody debris carried into navigable waters of the Puget Sound region and on the Washington coast, due to multiple atmospheric rivers and heavy precipitation impacting the region.
The art and science of designing and constructing new and modifying existing dams and levees is complex. The Risk Management Center (RMC), part of USACE’s Institute for Water Resources (IWR), is well acquainted with this challenge as the agency’s in-house expert on studying and making decisions to effectively manage infrastructure by reducing life safety risks.
Established in the aftermath of Hurricane Katrina, the RMC’s charge was...
