The Wallenpaupack hydroelectric plant is powered by the water contained by a 1,280-foot-long and 70-foot-high dam, which creates the popular 5,700-acre Lake Wallenpaupack. The lake has many benefits beyond clean, renewable electricity generation.

Electricity Generation

The generation process begins when water from the bottom of the lake flows into a 14-foot-wide pipe called a flow line.

The water travels 3.5 miles through the flow line to the power plant where it spins two turbines as it rushes past them. The turbines spin within each of the two generators to create 44 megawatts of electricity, which is enough power for about 35,000 typical homes. As the water exits the power plant, it flows into the nearby Lackawaxen River.

The ability of generation plants like Wallenpaupack to quickly respond to increases in electrical demand or fill in for large plants helps reduce stress on the electricity grid. Brookfield Renewable can also use the hydroelectric plant to manage lake levels in support of recreation or flood control, and to provide water to the Lackawaxen River in support of boating or fish habitat.

The lake also serves as a flood control resource for the Lackawaxen and Delaware rivers. The lake’s ability to hold water and store it for gradual release at an appropriate time helps to limit the effects of flooding downstream. We manage the lake level, in accordance with our FERC license, to support recreational uses and provide the maximum water-storage capability at times when flooding is most likely to occur.

Environmental Stewardship

Brookfield Renewable owns most of Lake Wallenpaupack’s shoreline and uses sound land management practices to help protect the quality of the lake’s water and the natural beauty of the shoreline.

The Federal Energy Regulatory Commission (FERC) granted its most recent license to Lake Wallenpaupack in 2005.

We are responsible for protecting the environmental, recreational, cultural, scenic and power production resources of the project.

We strive to balance the needs of these resources along the 52 miles of shoreline it owns around Lake Wallenpaupack. We also recognize that adjacent property owners, local residents and businesses, other users, and the environmental resources of the area are all important factors when making decisions affecting the use and access of the project lands and waters.

Brookfield Renewable owns most of Lake Wallenpaupack’s shoreline and uses sound land management practices to help protect the quality of the lake’s water and the natural beauty of the shoreline.

Permits for land and water uses

To meet our federal obligations, we require front-lot property owners to obtain permits for land and water uses that are on Lake Wallenpaupack’s property.

-Permits are issued for:

  • Boats
  • Docks
  • Earth Moving
  • Floats
  • Land
  • Vegetation Removal

Wallenpaupack Environmental Learning Center

The Learning center houses, the Lake Office and features:

  • Displays about hydroelectric generation, recreation opportunities and the history of the building of the lake
  • An auditorium
  • Science laboratory
  • Resource library
  • Offices and meeting rooms

For Directions

The center is used by community organizations that share an interest in clean water, conservation and resource preservation. It also provides office space to the Wallenpaupack Historical Society, Lake Wallenpaupack Watershed Management District , and the Pennsylvania Fish and Boat Commission .

Wallenpaupack Spillway Operation

Tue, May 05 , 02:03 pm

Beginning May 1, 2026, Brookfield Renewable may conduct intermittent, low‑flow water releases at the Wallenpaupack Dam to support repairs to the flowline.

These controlled releases are a routine, precautionary operational measure used to manage lake levels while maintenance activities are underway. There are no concerns for the dam and no anticipated impacts to downstream structures.

Releases through the spillway gates will result in increased flows in Wallenpaupack Creek and the Lackawaxen River during release periods. Low‑flow spill operations may occur periodically over the next eight weeks; this schedule is subject to change based on conditions.

Recreators and river users are encouraged to exercise caution near the dam and downstream waterways, remain alert to changing flow conditions, and follow all posted signage and audible warnings.

Updates will be provided as work progresses, and notification will be issued once spill operations have concluded.

If there are questions, please contact us at Inquiries.PA@brookfieldrenewable.com.

2026 Lake Wallenpaupack Drawdown

Wed, March 18 , 08:43 am

Starting after Labor Day, the Lake Wallenpaupack elevation will begin to draw down for regulated testing and maintenance of the dam. See below for the tentative schedule. Please note that lake levels, generation schedules, and drawdown plans may change without notice due to power‑grid needs or weather conditions.

Use caution when boating during the drawdown, as submerged hazards may be present.

For resource documents related to permitted shoreline projects or questions about the drawdown, please email Inquiries.PA@brookfieldrenewable.com.

Date (by week) Lake Level Target Elevation (in feet above sea level)
9/8 – 9/12 1180.50 to 1179.60
9/13 – 9/19 1179.30 to 1177.80
9/20 – 9/26 1177.60 to 1176.20
9/27 – 10/3 1175.90 to 1174.50
Week of 10/4 1174.50 to 1174.00

Spring Generation Restrictions

Thu, February 05 , 05:03 pm

Restricted generation for spring trout season will begin April 4, 2026 and continue through June 6, 2026. The modification of generation is to keep anglers safe on the Lackawaxen River. The schedule is subject to change based on the need for reservoir management due to weather and to regulate water temperature for the fishery downstream as required in our license. Please check the generating schedule frequently when recreating on the river. If there are questions, please contact us at Inquiries.PA@brookfieldrenewable.com.
