Abstract: In January 2008, East Branch Dam was determined by the U.S. Army Corps of Engineers (the Corps) to be potentially unsafe. To ensure public safety, the Corps’ Pittsburgh District temporarily changed the operation of the dam in February 2008 by lowering summer and winter pools to reduce hydraulic loads on and within the dam to acceptable levels. Since then, the District has formulated and evaluated repair alternatives, with the purpose of implementing an alternative that permanently reduces the risk of dam failure to meet the Corps’ tolerable risk guidelines. The need for this action is to reduce the probability of failure of the dam and, in turn, to reduce the potential risk of life loss, and economic and environmental impacts downstream. Measures have been developed by the District to assess the ability of each repair alternative to meet project needs, and criteria established that define the level of acceptable risk.
