PENNSYLVANIA RESERVOIR LEVELS

April 1 2025
       

Pennsylvania's dams and reservoirs play a crucial role in water supply, flood control, and recreation. As of the latest observations on April 1, 2025, there are notable variances in water levels when compared to historical averages. Prompton Reservoir is slightly below its average elevation of 1125.36 feet, currently at 1125 feet. Similarly, Blue Marsh Lake is under its average of 287.89 feet, at 286 feet, and Indian Rock Dam is significantly below its norm, with a current level of 371 feet against an average of 375.38 feet. Conversely, General Edgar Jadwin Reservoir is above its average by 1.8 feet, and Beltzville Lake near Parryville is marginally above its typical elevation. Lake Arthur at Moraine State Park, however, is aligning closely with its average level.

The disparities in reservoir levels could be attributed to various environmental conditions such as precipitation patterns, snowpack melting rates, and river flows. The lower levels at Indian Rock Dam and Blue Marsh Lake might indicate reduced inflow or higher water usage, possibly related to less snowpack or lower rainfall. Conversely, the slight increase in General Edgar Jadwin Reservoir's level might suggest higher-than-expected runoff or precipitation in its watershed. It's critical for authorities to monitor these conditions, as reservoirs experiencing abnormal levels could have implications for water availability, ecological health, and flood risk management. Decision-makers must consider these variations for effective water resource planning and to ensure the safety and functionality of the dam structures. These observations, when cross-referenced with other data sources, can provide a comprehensive picture of the state's water resource status and help predict any potential challenges that might arise due to these abnormal conditions.
