RESERVOIR LEVELS AS OF JANUARY 31, 2023
MDC reservoirs are at 99.9% of capacity.
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 (39.8 billion gallons) equivalent to 664 days, or 22 months of typical water use with zero rainfall..
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.
The MDC has specific drought protocols as part of our Water Supply Plan approved by the Connecticut Department of Public Health. A Drought Advisory is triggered when the reservoir capacity reaches 75%.
