PENNSYLVANIA RESERVOIR LEVELS

April 12 2025
       

Pennsylvania's reservoirs and dams play a crucial role in water supply, flood control, and recreation for the state. A recent overview of the latest observations, dated April 12, 2025, indicates that most reservoirs are at or near their average water surface elevations. Prompton Reservoir, for instance, is slightly below its average elevation of 1125.36 feet, currently sitting at 1125 feet. General Edgar Jadwin Reservoir is experiencing slightly higher than average water levels, currently at 991 feet compared to its average of 989.2 feet. Beltzville Lake near Parryville and Blue Marsh Lake are also marginally above their average levels, with current elevations of 628 and 288 feet, respectively. Meanwhile, Lake Arthur at Moraine State Park is nearly in line with its average at 1190 feet. These figures suggest that, in general, Pennsylvania reservoirs are maintaining stable conditions, which is essential for the reliable operation of dam infrastructure and downstream water management.

However, one anomaly in the dataset is the Indian Rock Dam, which shows a current elevation of 371 feet, significantly lower than its average of 375.38 feet. This deviation could be indicative of abnormal conditions such as reduced snowpack leading to lower inflows or increased water usage upstream. The lower than expected levels at Indian Rock Dam may require close monitoring and potential management adjustments to address any water supply or ecological concerns that could arise from such a disparity. It’s also important to cross-reference these observations with other data sources, such as river flow measurements and weather patterns, to assess the broader implications of these levels. Ensuring the accuracy of these observations is critical, as they have direct implications on water management strategies and could be reflective of larger environmental trends that need to be addressed both in the short and long term.
