Water Management

Roadmap of District with projectsKnown 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. The Pittsburgh District’s Water Management Section provides accurate and timely information on conditions at Corps of Engineers reservoirs, as well as levels along rivers and streams within the Pittsburgh District.

Weekend Recreation Outlook

Collapse All Expand All

Updated on 29 October 2015

Today Conemaugh Lake was releasing 580 cfs this morning but increased the outflow to release 2200 cfs this afternoon. Conemaugh's pool today was at 905.7 ft (NAVD88) and rising. This morning the Vandergrift stage was at 4.28 ft. We plan to hold Conemaugh's discharge at 2200 cfs for the weekend.  The Vandergrift gage is expected stay above 4.0 ft. through the rest of the weekend.  The current observed Vandergrift stage is available here.  This will be the last weekend that we updated the Weekend Recreation Outlook since the recreational season is coming to a close.

The weather forecast for Vandergrift is provided by the National Weather Service.

Our primary reference for canoeing information is Roy Weil and Mary Shaw’s Canoeing Guide to Western Pennsylvania and Northern West Virginia. It indicates levels that are recommended limits for safe canoeing on the Conemaugh and Kiski.

Long Term Outlook

Both Conemaugh River Lake and Loyalhanna Lake are "flood control only" projects, thus there is no storage allocated in either lake for low flow augmentation, recreation enhancement or any other purpose. All other potential benefits can only be accommodated if there is no significant impact on their authorized purpose of flood control.

That said, during the summer recreation season, we attempt to time our operations to enhance recreational opportunities on the Kiski River, to the extent practicable.

As always, we are operating Conemaugh and Loyalhanna Lakes in accordance to their authorized project purpose of flood control. Operations (gate changes) can only be made for project purposes for which storage has been allocated. Any other project purposes (i.e., recreation) are accommodated to the extent feasible.

Today Youghiogheny Dam was releasing 700 cfs this morning but reduced the outflow to 500 cfs this afternoon.  Youghiogheny's pool today was at 1388.8 ft (NAVD88) and falling. We are releasing the minimum required flow for the current flow schedule. Current Ohiopyle gage is 3.13 ft. We plan to hold Youghiogheny's discharge at 500 cfs for the weekend. Current and projected lake levels and releases are shown here. This will be the last weekend that we updated the Weekend Recreation Outlook since the recreational season is coming to a close.

The current NWS River Forecast for Ohiopyle can be found here. Corps reservoir release forecasts are always built into the NWS river forecasts, so the effects of our release changes are shown there.

The weather forecast for Ohiopyle is provided by the National Weather Service.

Lake recreation users can call (814) 395-3166 for the current recorded information message on daily pool and outflow levels, safety, recreation, special events and fishing.

You can also call Ohiopyle State Park at (724) 329-8591 to hear a recorded message giving the daily stage reading.

Long Term Outlook

We are operating under the established low water regulation schedule and will continue to maintain downstream flow schedules. Youghiogheny River Lake's target summer pool range is between 1438.4 ft and 1440.4 ft (NAVD88).

As always, we are operating Youghiogheny River Lake in accordance with its authorized project purposes of flood control, low flow augmentation for water quality 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.
