MARYLAND RESERVOIR REPORT

Last Updated: March 4, 2026

Maryland's reservoirs are essential for water supply, flood control, and recreational activities. Among the notable ones, Atkisson Reservoir near Bel Air, Bloomington Lake near Elk Garden, and Savage River Reservoir near Bloomington play significant roles. The latest data shows that Bloomington Lake's water surface elevation is currently 1452 feet above the North American Vertical Datum of 1988 (NAVD 1988), which is slightly higher than its average of 1446.2 feet. On the other hand, Savage River Reservoir's current level is 1441 feet, a bit lower than its average of 1446.33 feet. Unfortunately, the current storage level data for Atkisson Reservoir is unavailable, as indicated by an invalid entry (-999999). These findings are based on observations last made on March 4th, 2026.

The deviations from average levels in these reservoirs can signal abnormal conditions. Bloomington Lake's elevated levels could be the result of recent above-average precipitation, snowmelt, or increased inflow from upstream sources. Conversely, the lower than average water level at Savage River Reservoir suggests potential concerns such as reduced snowpack, lower river flows, increased water usage, or leakage issues. The lack of updated data for Atkisson Reservoir prevents an accurate assessment, but such a data gap itself could be a point of concern and necessitates further investigation to ensure the reservoir's integrity and operational status. It's crucial to cross-reference these findings with multiple data sources, including local water authorities and environmental agencies, to confirm the reliability of the observed data and to understand the implications of these abnormal conditions for water management and regional ecology.

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.
