Authorized by the Rivers and Harbors Act of 1935, Tygart Dam was the first of 16 flood control projects of the
Pittsburgh District of the US Army Corps of Engineers. The dam provides flood protection for the Tygart River
Valley as well as for the Monongahela and upper Ohio Rivers. In addition to flood control, the Tygart dam was
also authorized for navigation and water supply purposes. During the summer and fall low-water season, water
is released from the dam to meet the requirements for navigation on the Monongahela and Ohio Rivers. The
increased flow also improves water quality and quantity for domestic and industrial use, recreation,aesthetics
and aquatic life.
