Reservoir Data

The Drinking Water Section monitors reservoir levels submitted by the 34 public water systems that utilize surface water supplies. Current reservoir capacity levels are compared to historical records, noting any trends that may be indicative of approaching drought conditions.  This information is collected monthly and detailed data can be viewed below. Water resources are generally ample in Connecticut. Prolonged droughts are infrequent; however, considerable weather changes can occur over short periods of time. During periods of low precipitation you should follow recommendations from your public water supplier for appropriate levels of water use.  Always use water wisely to help: Save Water, Save Money, and Save Energy.
