February 2018 Reservoir Levels
Normal storage refers to the volume that is useable for water supply. The full capacity of the two Patuxent reservoirs is 11.93 billion gallons, which is higher than normal storage (10.57 billion gallons); therefore, full capacity values can exceed 100 percent of normal storage. Note: The Triadelphia Reservoir storage level is low because of an ongoing project and will be kept low until 2019 or until the project is complete. |
