The Baltimore City Department of Public Works (DPW), in coordination with Baltimore County, Harford County, Howard County, and Carroll County, has issued a voluntary water restriction due to historically low levels at Liberty Reservoir—one of the region’s primary drinking water sources—which has dropped to its lowest point in nearly two decades.

To help protect our regional water supply, DPW has made operational changes at the Montebello and Ashburton Water Filtration Plants—reducing the amount of water drawn from Liberty Reservoir and increasing use of the Loch Raven Reservoir. To support this effort, voluntary water use restrictions are in place for the entire service area, including all surrounding counties. Everyone is encouraged to do their part to help conserve water and ensure enough supply for essential needs.

These voluntary restrictions apply to all customers in the Baltimore region who receive public water service. Those who rely on private wells are not affected but should consult their local county or city officials for any relevant guidance.

With rainfall levels significantly below seasonal averages, these voluntary restrictions are aimed at preserving the regional water supply as the Baltimore area approaches the high-demand spring and summer seasons. Liberty Reservoir, located in eastern Carroll County, has been notably impacted by below-average rainfall and increasing seasonal demand. Loch Raven and Prettyboy reservoirs are also experiencing declining water levels.

“We are urging all residents and businesses to voluntarily conserve water to help preserve our regional water supply,” said Mayor Brandon M. Scott. “By taking collective action now, we are trying to mitigate the need for more stringent measures in the future.”

“DPW is closely monitoring the situation and will continue to assess rainfall and reservoir levels over the coming weeks and months,” said DPW Director Khalil Zaied. “We are urging everyone to voluntarily conserve water now to help ensure the long-term sustainability of our regional supply.”

Recommended Water Conservation Measures
DPW and its regional partners request all residents and businesses to voluntarily reduce non-essential water use by:

Postponing lawn and garden watering

Avoiding car, boat, or equipment washing

Refraining from washing outdoor surfaces like sidewalks and driveways

Repairing or replacing leaking faucets, hoses, and sprinklers

Running only full loads in dishwashers and washing machines

Turning off taps while brushing teeth or shaving

Leaks are one of the largest sources of water waste. DPW is committed to doing its part by repairing watermain breaks and system leaks promptly. Residents are encouraged to help by reporting any signs of running water that may indicate a leak or watermain break.

Potential Use of Susquehanna River as Backup Supply
If conditions worsen, DPW may draw from the Susquehanna River—typically used only during drought conditions. While the water is treated and safe to drink, residents may notice a slight change in taste.

DPW will continue to monitor conditions and provide updates. The voluntary restrictions will be reassessed as the region progresses through spring and summer.
