Maryland Drought Emergency Water Use Authority

Under the Environment Article and the Maryland Drought Plan, the Maryland Department of the Environment performs monthly evaluations of precipitation, stream flow, groundwater levels, and reservoir storage. MDE issues drought watches, warnings, and emergencies based on hydrologic indicators. When the Governor declares a Drought Emergency by executive order, mandatory statewide restrictions on outdoor water use, lawn watering, vehicle washing, and similar activities take effect and supersede less restrictive local rules. Local water utilities may always impose stricter conservation measures but cannot loosen state emergency requirements.

During a declared drought emergency, violating mandatory water use restrictions can result in civil penalties enforced by MDE and local water suppliers, including fines and service penalties.
