PENNSYLVANIA RESERVOIR LEVELS

April 7 2025
       

In Pennsylvania, the status of dams and reservoirs is continuously monitored to ensure water levels are within safe and operational ranges. As of the latest observations dated April 7, 2025, there have been noticeable variances in water surface elevations across several key water bodies when compared to average historical data. Prompton Reservoir and Beltzville Lake near Parryville are slightly below their average levels, recording 1125 feet and 628 feet respectively, against their averages of 1125.36 feet and 627.58 feet. General Edgar Jadwin Reservoir is marginally above its average at 991 feet, compared to an average of 989.2 feet. Blue Marsh Lake and Indian Rock Dam are experiencing more significant deviations from their average levels, with Blue Marsh Lake at 287 feet (average 287.89 feet) and Indian Rock Dam at 371 feet (average 375.38 feet). Lake Arthur at Moraine State Park is nearly at its expected average with a current level of 1190 feet against an average of 1190.19 feet.

The abnormalities in water levels can be attributed to various environmental factors. Notably, Western Pennsylvania has been experiencing more rounds of rain according to WTAE, which may contribute to higher water levels in the General Edgar Jadwin Reservoir. On the other hand, areas such as Blue Marsh Lake and Indian Rock Dam could be influenced by lower precipitation or other factors such as snowpack conditions and river flows. Snow accumulation totals from a recent weekend event from Michigan to Buffalo, New York, reported by AOL.com, suggest that snowpack may not have significantly contributed to the reservoir levels in Pennsylvania. It is important to cross-reference these observations with long-term climate data and ongoing weather patterns to understand the full scope of these variances. Seasonal trends, such as those discussed at the 2025 Philadelphia Flower Show, highlight the broader shifts in eco-friendly gardening that could also be indirectly impacting water usage and reservoir levels. Monitoring will continue to ensure any potential risks associated with these abnormal conditions are mitigated and that water resources are managed effectively.
