Lake Williams Dam Project

Lake Williams Dam Project FAQ’s

October 6, 2021:


Lake Williams reservoir has been lowered about 6 feet, in accordance with Fish and Boat Commission requirements. This lowering is necessary in order to start the planned work on the Lake Williams Dam. In 2022 and most of 2023, the Lake Williams reservoir will need to remain lowered for dam reconstruction. Because we can pull water for treatment from Lake Redman, your water supply and that of all York Water’s customers will not be affected by the temporary drawdown and construction at Lake Williams. Our investments in operational flexibility will allow us to continue to provide the same high-quality water that The York Water Company takes pride in delivering. However, we recognize that the temporary viewshed and appearance will not be typical.

April 9, 2021:

Geotechnical investigations on and around the dam have been completed. Design plans for renovation of the dam and spillway are being prepared by our engineering consultant. The Water Street Bridge remains closed to vehicle traffic.

Geotechnical investigations are being conducted on and around Lake Williams Dam. This work is part of a major renovation project to enhance dam safety for the downstream public. York Water estimates the site investigations will continue to the end of 2020.

York Water is in the midst of a three-phase dam improvement project that will span over several construction seasons. Phase 1 work has been completed and Lake Williams’ gates are now up, and the lake is at full capacity. We are awaiting DEP approval for Phase 2 work to reconstruct the dam’s spillway to current design standards. Once approval is granted, we will need to lower the water level 20 feet to complete the spillway construction work.

Lake Williams is “full” to the bottom of the bascule gates. The gates are in the down position and will remain in the down position until after the Lake Williams Project is complete. The gates are 4′ high, so Lake Williams is 4′ below normal full elevation.

The crossing on Water Street is now open to pedestrians, bicycles, and horses. The road remains closed to motorized vehicles.

Lake Williams is back open to boating and fishing. York Water has been working with the PA Fish and Boat Commission to begin the process of restocking the fish in Lake Williams.
