Lake Aldred will be lowered on Friday (6/4) from 6 a.m. to 7 p.m. to allow repairs on flashboards at PPL Corporation’s Holtwood Dam.

The repairs are needed because high river flows have damaged the flashboards, said Mark Arbogast, PPL’s assistant superintendent-Environmental Preserves. Flashboards are wooden planks fixed on top of the dam that hold back river flows to help PPL’s Holtwood hydroelectric plant run more efficiently.

When lake levels are lowered, PPL discourages recreational boating and fishing because of shallow and rocky water.

"Boaters also should take care not to get closer to the dam than the large warning signs about one mile upstream because it’s extremely dangerous to get too close," Arbogast said.

Lake Aldred is an 8-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.
