PENNSYLVANIA RESERVOIR LEVELS

April 26 2025
       

In Pennsylvania, the monitoring of reservoir and dam storage levels is a critical aspect of water resource management, particularly in periods of abnormal environmental conditions. Recent observations from the state's major reservoirs, such as the Prompton Reservoir, General Edgar Jadwin Reservoir, Beltzville Lake, Blue Marsh Lake, Indian Rock Dam, and Lake Arthur at Moraine State Park, indicate varied water surface elevations. For instance, as of April 26, 2025, the Prompton Reservoir's water surface elevation slightly dipped below the average of 1125.36 feet to 1125 feet. Similarly, Indian Rock Dam's current water level is at 371 feet, noticeably lower than the usual 375.38 feet. Conversely, the General Edgar Jadwin Reservoir and Blue Marsh Lake are both experiencing water levels above their respective averages, with current measurements at 991 feet and 290 feet, exceeding the average by 1.8 feet and 2.11 feet. This mix of above and below-average water levels could be attributed to varied factors such as precipitation patterns, watershed runoff, and possibly the effects of regional wildfire smoke as reported by the Department of Environmental Protection and local news sources.

Concerning abnormal conditions, Blue Marsh Lake and General Edgar Jadwin Reservoir have elevated water levels, possibly a consequence of recent precipitation events or altered river flows. The ongoing Michaux State Forest fire, as reported by local news, could contribute to atmospheric changes affecting precipitation patterns. Conversely, the lower water level at Indian Rock Dam may point to decreased inflows or increased water usage downstream. It's vital to cross-reference these observations with multiple data sources, such as government reports and news articles, to ascertain the reasons behind these discrepancies. For example, the DEP's alerts about enhanced air quality levels due to wildfire smoke could indicate atmospheric conditions that may influence local weather and hydrology. Consideration of such multifaceted data sources is critical for a comprehensive understanding of the water resources in Pennsylvania's reservoirs and dams, ensuring effective management and preparedness for any potential water-related issues.
