Baltimore City Department of Public Works Director Rudolph S. Chow, P.E., announced today that Baltimore’s three raw-water reservoirs will enter autumn with an abundant supply of water for our 1.8 million customers.

As of the last week of August the reservoir storage totals are:

Liberty            36.80  billion gallons           100% full

LochRaven      21.20  billion gallons           100% full

Prettyboy         17.48  billion gallons           98% full

Total                 75.85  billion gallons           99% full

Full reservoirs mean that our customers in metropolitan Baltimore should continue to have an ample water supply through the fall, winter, and spring. The very wet summer, especially the wettest July on record, has provided us with this very positive outlook.

Baltimore’s drinking water comes from the three reservoirs listed above, and these are replenished by rainfall and snowmelt. When droughts occur, the reservoir storage amounts decrease, sometimes to the point where water must be drawn from the Susquehanna River to blend with reservoir water at our Montebello Treatment Facilities. A third facility at Ashburton processes water from Liberty, the largest of the three reservoirs.

Our Reservoir Natural Resources staff work diligently to protect the watersheds around these reservoirs to ensure the health and stability of natural vegetation, which in turn protects the water quality as well as the native wildlife. They also work to remove and prevent harmful invasive species from the land and water, and they maintain the fisheries and operate the dams.

A lot of work goes in to just collecting, storing, and protecting our raw water supply!  

Help protect our water resources by following all posted rules and regulations when visiting reservoir property. And, please remember to always use water wisely.
