PENNSYLVANIA RESERVOIR LEVELS

April 13 2025
       

Pennsylvania's dams and reservoirs are integral components of water resource management, providing water supply, flood control, and recreation. As of the latest observations on April 13, 2025, the Prompton Reservoir, General Edgar Jadwin Reservoir, Beltzville Lake near Parryville, Blue Marsh Lake, and Lake Arthur at Moraine State Park are all reporting water surface elevations close to their average levels. Prompton Reservoir is a slight exception, with a current level of 1125 feet, marginally below its average of 1125.36 feet. The Indian Rock Dam, however, is showing an elevation of 371 feet, which is notably lower than its average of 375.38 feet. This summary provides a snapshot for non-specialists looking to understand the general status of Pennsylvania's water resources.

Upon detailed examination, while most reservoirs are maintaining expected levels, the Indian Rock Dam's lower than average water surface elevation might indicate potential concerns such as reduced inflow or increased water releases. In contrast, the General Edgar Jadwin Reservoir is slightly above its average level at 991 feet, possibly due to recent precipitation events or controlled water management activities. It's essential to cross-reference these findings with regional snowpack data and river flow records to determine if these conditions are part of normal seasonal fluctuations or if they signal more significant hydrological changes. For instance, a lower than normal snowpack could lead to reduced river flows and subsequently lower reservoir levels, as might be the case with Indian Rock Dam. Conversely, if the region has experienced above-average snowpack or precipitation, this could explain the higher water levels observed in the General Edgar Jadwin Reservoir. Continuous monitoring and cross-referencing with meteorological data are crucial to understanding these trends and predicting their implications for water management and potential flood risks.
