MARYLAND RESERVOIR REPORT

Last Updated: January 1, 2026

In Maryland, the state of dams and reservoirs is critical for water supply, flood control, and environmental health. Recent observations indicate variable conditions across major facilities. Atkisson Reservoir near Bel Air, typically at an average water surface elevation of 119.43 feet above the North American Vertical Datum of 1988 (NAVD 88), is currently not reporting data, which could indicate sensor issues or other reporting problems as of the last observation on January 1, 2026. Bloomington Lake near Elk Garden, usually at 1446.62 feet, is slightly below normal at 1418 feet. Similarly, Savage River Reservoir near Bloomington, with a typical average of 1446.88 feet, is also experiencing lower levels at 1421 feet. These measurements provide an overview of reservoir conditions, potentially highlighting areas needing attention or further investigation.

The deviations from average levels in Bloomington Lake and Savage River Reservoir may be attributed to various factors, such as reduced snowpack leading to lesser spring runoff, below-average precipitation, or increased water usage. The absence of data for Atkisson Reservoir warrants concern and requires immediate attention to ensure accurate monitoring. These abnormal conditions, particularly the reduced water levels at Bloomington and Savage River, could have implications for local water supply and ecosystem health if they persist. With these observations, Maryland authorities may need to review water management policies, consider conservation measures, and prepare for potential impacts on water-related activities. It is vital to continue cross-referencing with multiple data sources to ensure the reliability of these findings and to promptly address any abnormal reservoir conditions.

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.
