Is the DSAC rating system new? How does it work?
The Corps’ Dam Safety Action Classification (DSAC) began in 2005 in response to a comprehensive peer review of the Corps’ Dam Safety Program through the Association of State Dam Safety Officials. The ASDSO recommended the Corps of Engineers develop risk reduction, risk assessment and risk management procedures for implementing a nationwide evaluation process that prioritizes the funding and allocation of dam safety resources Corps-wide. This ASDSO recommendation was the catalyst for initiating risk based screening of Corps dams, and the subsequent Expert Panel review of the Corps’ highest risk dams. The Corps categorized dams into Dam Safety Action Classes (DSAC) based on their individual dam safety risk considered as probability of failure and potential failure consequences.
