Water Supply


RESERVOIR LEVELS AS OF MAY 22, 2017
MDC reservoirs are at 97% of capacity with over 38 billion gallons in storage representing 649 days of supply assuming typical water use and no precipitation.

The MDC’s water supply consists of a surface water supply system of reservoirs that includes the 30.3 billion gallon Barkhamsted Reservoir and the 9.5 billion gallon Nepaug Reservoir.  When full, these two reservoirs store a volume of water equivalent to 660 days, or 22 months of typical water use.

Because of the large size of its reservoirs relative to the amount of water typically used, the MDC is better able to meet water use demands during water use restriction conditions.
