The water level on Lake Aldred will be lowered Friday (5/18) and Saturday (5/19) from 6 a.m. to 6 p.m. to allow for repairs and maintenance at PPL Corporation’s Holtwood Dam.

High river flows this spring have damaged flashboards, which are large wooden boards fixed to steel pins atop the concrete dam. They raise the elevation of the water held back by the dam and make the Holtwood hydroelectric plant more productive and efficient. With the river flows dropping, PPL will take the opportunity to repair the damaged flashboards.

Boating is not recommended when lake levels are low because of shallow water and exposed rocks and hazards.

“Boaters should always be aware of river conditions and should use caution below the large warning signs about one mile upstream of the dam,” said Mark Arbogast, assistant superintendent of PPL’s Environmental Preserves.

While the water level of Lake Aldred is lowered, PPL also will be doing repairs to the Pequea Boat Ramp. The boat ramp will be closed Friday (5/18) and will reopen Wednesday (5/23).

Lake Aldred is an eight-mile-long body of water formed by the Holtwood Dam on the lower Susquehanna River. PPL owns and maintains more than 5,000 acres of land for public use on both sides of the lake in York and Lancaster counties in southeastern Pennsylvania.
