Sustainable Solutions

The level of water in reservoirs rises and falls throughout the year. Reservoirs are at their highest levels in the spring when they fill with rain and snowmelt. That water is used throughout the summer and early fall. Water levels begin to rise again in November when leaves are off the trees and people are using less water outdoors. The RWA has records of water levels dating back almost 100 years, and we use that information to calculate a long-term average for the amount of water in the reservoirs for each month.

Water Supply Status as of August 31, 2019

Current Status:
Our reservoirs are at 87% of capacity.

Normal Status for Time of Year:
Reservoirs are usually at 74% of capacity.

Storage by System:

North Branford 86%
Saltonstall 90%
West River 90%
Whitney 84%

To make sure we have enough water for public health and fighting fires, we have a drought response plan based on the long-term average. The drought response plan calls for specific actions that the RWA and consumers can take at each level. The RWA makes changes to its operations to increase the amount of water available and to save as much water as possible. As a drought becomes more serious, there will be requests to reduce water consumption at each level, starting with 10 percent at the Advisory Threshold and continuing to water rationing if we’re in a state of emergency.
