MARYLAND RESERVOIR REPORT

Last Updated: December 28, 2025

Maryland, known for its diverse range of landscapes and waterways, is home to several critical dams and reservoirs that serve as important resources for water supply, recreation, and flood control. Recent observations reveal varied water storage levels in these structures. The Atkisson Reservoir near Bel Air, which typically averages a water surface elevation of 119.43 feet above the North American Vertical Datum of 1988 (NAVD 1988), is currently experiencing a data gap, with the last recorded surface elevation showing as unavailable. This lack of data creates uncertainty regarding its current status. On the other hand, the Bloomington Lake near Elk Garden and the Savage River Reservoir near Bloomington are reporting water elevations of 1416 feet and 1420 feet above NAVD 1988, respectively. These levels are notably lower than their average elevations of 1446.68 feet and 1446.92 feet, which may be indicative of abnormal conditions.

The reduced water levels in Bloomington Lake and Savage River Reservoir could be attributed to factors such as lower-than-average snowpack, decreased river flows, or increased water usage. The absence of data for Atkisson Reservoir hinders analysis, but the deviation from average levels in the other two reservoirs raises concerns about potential water shortages or the need for conservation measures. As the reservoirs are integral to Maryland's water management, authorities may need to investigate and address the underlying causes of these discrepancies. It is essential for local stakeholders and residents to remain informed about their water resources, particularly in light of these abnormal conditions. Cross-referencing with additional data sources would further clarify the situation, but the provided dataset does not include such references. Nonetheless, the current observations suggest that close monitoring and perhaps strategic management are required to ensure the continued health and efficacy of Maryland's dams and reservoirs.

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.
