MARYLAND RESERVOIR REPORT

Last Updated: December 21, 2025

In Maryland, several key dams and reservoirs play a critical role in water storage, flood control, and recreation. Recent observations reveal varying conditions across these water bodies. Atkisson Reservoir near Bel Air, typically with an average surface elevation of 119.43 feet, is currently unreported due to a data error indicated by the placeholder value of -999999, making it difficult to assess its status. However, Bloomington Lake near Elk Garden and Savage River Reservoir near Bloomington show a decrease from their average levels of 1446.78 feet and 1447.02 feet to 1413 feet and 1418 feet, respectively. As of the last observed date on December 21, 2025, these deviations suggest a lower water intake, which could be a matter of concern if they continue to stray from their typical ranges.

A closer look at Bloomington Lake and Savage River Reservoir indicates that they are experiencing lower than average water surface elevations. This decline could potentially be related to factors such as below-average snowpack, reduced river flows, or increased water usage and evaporation rates. Without normal replenishment from snowmelt and river inflows, reservoirs may struggle to maintain their capacity, potentially affecting water supply and ecological health. The abnormal reading for Atkisson Reservoir requires additional investigation to determine its status. It's crucial for local authorities to monitor these conditions, as prolonged discrepancies could lead to water restrictions or impact the ecosystems reliant on these water bodies. Cross-referencing with multiple data sources and further on-site inspections will be essential to validate these observations and understand the broader implications for Maryland's water management strategy.

Maryland has numerous reservoirs and dams, with the largest being Loch Raven Reservoir, Prettyboy Reservoir, and Liberty Reservoir. The streams, rivers, and creeks that provide water to these reservoirs include the Gunpowder Falls, Patapsco River, and the North Branch Potomac River. The mountains and snowpack in the western part of the state are relevant as they contribute to the streamflow in these rivers. The hydrology in the area is influenced by the Chesapeake Bay and its water levels, which are affected by tidal cycles and precipitation. In recent years, Maryland has experienced drought conditions and record low streamflow levels, leading to water restrictions and conservation efforts. Seasonal trends include higher water levels in the spring due to snowmelt and increased precipitation, followed by lower levels in the summer and fall. Overall, reservoirs and dams play an important role in providing water to Maryland's population and supporting various industries, including agriculture and tourism.
