NOTICE – LAKE FREDERIC/YORK HAVEN STATION PLANNED LAKE DRAWDOWN STARTING ON TUESDAY, SEPTEMBER 3, 2024
On Tuesday, September 3, 2024, York Haven Power Company (YHPC) plans to slowly lower Lake Frederic, the reservoir upstream of the York Haven main dam, for maintenance required by the Federal Energy Regulatory Commission (FERC). Lake Frederic will be lowered for up to 6 weeks (weather dependent). Boaters should use caution on Lake Frederic due to low water levels. Some of the access ramps may not be suitable for use by larger vessels. Water levels are expected to go below 277 ft elevation by about 14 inches. Required minimum flows at the main dam will be maintained.

***********************
York Haven Power Company, LLC (YHPC), began construction of a nature-like fishway (NLF) on the southwest bank of Three Mile Island in August 2024. The purpose of the NLF is to improve fish passage and connectivity in the Susquehanna River. This involves some construction noise. As required by the Federal Energy Regulatory Commission (FERC), we are restricting construction to 7 a.m. to 7 p.m., Monday through Saturday. We hope you will please excuse any noise, as it is part of an exciting project to improve the environment through better fish passage on the Susquehanna River. Throughout September and October 2024 we are stripping and stockpiling topsoil, modifying the crest of the dam adjacent to the future fishway, and installing a sheet pile wall. Excavation of the fishway is scheduled to begin in November 2024.
York Haven Power Company, LLC (YHPC), comenzó la construcción de una vía para peces similar a la naturaleza (NLF) en la orilla suroeste de Three Mile Island en agosto de 2024. El propósito del NLF es mejorar el paso de peces y la conectividad en el río Susquehanna. Esto implica algo de ruido de construcción. Como lo requiere la Comisión Federal Reguladora de Energía (FERC), estamos restringiendo la construcción de 7 a.m. a 7 p.m., de lunes a sábado. Esperamos que disculpen cualquier ruido, ya que es parte de un proyecto emocionante para mejorar el medio ambiente a través de un mejor paso de peces en el río Susquehanna. A lo largo de septiembre y octubre de 2024 estamos desmontando y acopiando la capa superficial del suelo, modificando la cresta de la presa adyacente a la futura NLF, y instalando un muro de tablestacas. Está previsto que la excavación de la vía para peces comience en noviembre de 2024.
