Water Management

Known as the Headwaters District, the Pittsburgh District is comprised of the Ohio River drainage basin above New Martinsville, West Virginia. The District covers an area of approximately 67,000 square kilometers (26,000 square miles), including portions of Pennsylvania, West Virginia, Ohio, New York and Maryland. Major river systems within the Pittsburgh District include the upper Ohio, the Allegheny, the Monongahela and the Beaver. The District manages 16 flood control and multipurpose reservoirs with a combined capacity of over 3.8 billion cubic meters (3 million acre feet) and 23 navigation locks and dams on 530 kilometers (330 miles) of navigable waterways. In addition, the District operates Lake Milton for the state of Ohio. Pittsburgh District Water Management provides accurate and timely information on conditions at Corps of Engineers reservoirs, as well as levels along rivers and streams within the Pittsburgh District.

Long Term Outlook

As always, we are operating Youghiogheny River Lake in accordance with its authorized project purposes of flood control, water quality control, and water supply. Operations (gate changes) can only be made for project purposes for which storage has been allocated. Other project purposes (i.e., fish and wildlife enhancement and recreation) are accommodated to the extent feasible. We continue to attempt to operate the project considering the needs of recreation users both on the lake and the river.

The outlooks above are generally updated every Thursday during recreation season.
