These included concentrated leak erosion along the conduit, internal erosion below the fixed crest spillway, and a hydraulic jump seep-out in the spillway stilling basin at extreme floods. The spillway was reconstructed in 2000 primarily because of a similar internal erosion distress, and the conduit was grouted in the 1980's because of concerns for concentrated leak erosion. The risk of all potential failure modes was determined to be low and tolerable.", "riskManagementMeasures":"USACE manages dam-related flood risks by continually monitoring the condition and health of the dam, prioritizing activities that will most impact the risks.
