MARYLAND RESERVOIR REPORT

Last Updated: December 24, 2025

Maryland's dams and reservoirs are essential components in the state's water management system, serving multiple purposes, from water supply and recreation to flood control and environmental protection. The latest dataset concerning these structures reveals notable variations in storage levels, which are key indicators of their operational status. Atkisson Reservoir near Bel Air, for instance, currently lacks a reliable measurement, as indicated by the placeholder value of -999999, suggesting either a malfunction in the data recording equipment or a lapse in reporting as of the last observed date on December 24, 2025. Without updated figures, it's difficult to assess its condition accurately. On the other hand, Bloomington Lake near Elk Garden and Savage River Reservoir near Bloomington are showing water surface elevations below their respective averages, with Bloomington Lake at 1414 feet and Savage River Reservoir at 1418 feet, compared to their usual averages of 1446.73 and 1446.98 feet.

These abnormal conditions could be a result of several factors. The lower-than-average levels at Bloomington Lake and Savage River Reservoir suggest potential issues such as decreased snowpack melting into the watersheds, reduced river flows, or increased water consumption or release protocols. Typically, reservoirs in Maryland would rely significantly on winter snowpack and spring runoff to replenish their levels. If the region experienced a mild winter with less snowfall, this could account for diminished inflow into the reservoirs. Additionally, river flows feeding into these reservoirs could have been affected by upstream water usage or diversions. It is also possible that planned or emergency releases from these reservoirs have been carried out to manage downstream flood risks or to maintain ecological balance, further influencing water levels. A cross-reference with multiple data sources, including local water authorities, meteorological reports, and hydrological data, would be essential to confirm the reasons behind these observations and to evaluate the full impact on water resource management in the state. As of now, the precise cause of the abnormal conditions at these key Maryland dams remains uncertain without additional context or data.

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.
