PROJECT FACTS
Background:
The dam site is located on Rough River, 89.3 miles east of the confluence with the Green River. Repairs are necessary to ensure the dam continues to function as it was designed for another 50-plus years. Through investigations, analyses and enhanced monitoring the Corps identified compelling evidence to warrant remedial construction. The specific concern with Rough River Dam is the karst features of specific geologic formations that lie beneath the dam. There has been no surface distress observed at the dam related with these features; however, these formations have been identified to have the potential to weaken the dam embankment. Enhanced monitoring throughout the study has indicated that adverse seepage flow may be developing within these features following the 2011 record pool. It is imperative to address theses potential concerns before they worsen over time.
Project Plans: The planned two-phased construction project will rehabilitate the foundation to eliminate seepage concerns. The construction involves grouting of the bedrock as an initial phase. Based on the conditions encountered, a decision will be made whether to go to Phase 2 which could involve a deep concrete cutoff wall through the embankment and into the foundation rock.
At this time, no adjustments to pool level will occur. However, at some point during the construction it may be necessary to temporarily hold the lake below the normal recreation pool level (summer pool 495 feet). Public safety is the Corps' number one concern, and the Corps personnel will continue to communicate progress on the project.
