NOTICE – LAKE FREDERIC/YORK HAVEN STATION PLANNED DRAWDOWN
Starting as early as June 12 2023, York Haven Power Company (YHPC) plans to lower Lake Frederic, the reservoir upstream of the York Haven main dam for maintenance required by the Federal Energy Regulatory Commission (FERC). This will involve lowering Lake Frederic for up to 8 weeks. Water levels are expected to go below 277 ft elevation by 14 inches. Required minimum flows at the main dam will be maintained.
We have received a number of questions on whether the water level could be raised on weekends or for the July 4th holiday. YHPC will not realistically be able to raise the level on weekends, but is discussing July 4th with the vendor.
An update will be provided to parties on our Notification List weekly after the drawdown commences.
Please send questions or requests to be added to our Notification List for updates to firstname.lastname@example.org.
