CONNECTICUT RESERVOIR REPORT

Last Updated: December 24, 2025

The latest observations of the nation's dams and reservoirs present a mixed picture of water storage levels, with some areas experiencing surpluses due to recent inflows, while others face drought conditions with below-average water levels. Notably, major reservoirs such as Lake Powell in Arizona and Lake Mead in Nevada reveal a concerning trend, with storage levels falling significantly short of their historical averages, reflecting extended periods of drought and increased water demand in the Southwest. Conversely, California's Lake San Antonio has seen a surge in water levels, exceeding its average and demonstrating the variability of water supplies across different regions.

For water management researchers and hydrologists, the data underscores the importance of monitoring and adaptive management strategies to address the challenges posed by climate variability and human impact on water resources. Reservoirs like Lake Powell, currently at only 44% of average storage, and Lake Mead with less than half its average, are stark reminders of the long-term water scarcity issues facing the Colorado River Basin. Meanwhile, reservoirs such as California's Lake San Antonio, which now holds over twice its average storage, showcase the benefits of effective catchment during periods of heavy precipitation. The contrasting conditions highlight the need for dynamic management approaches that consider both the immediate and future water needs, in addition to the environmental and economic impacts of fluctuating water levels.

Connecticut has numerous reservoirs and dams used for water supply, flood control, and recreational purposes. Some of the major reservoirs in the state include the East Branch Reservoir, West Branch Reservoir, and Saugatuck Reservoir. These reservoirs are fed by streams and rivers such as the East Branch of the Saugatuck River and the West Branch of the Saugatuck River. The water supply is heavily influenced by seasonal snowpack, particularly in the mountains of northern Connecticut. Connecticut generally experiences a humid continental climate with cold winters and warm summers. There have been instances of record drought conditions in the state, particularly during the summer months. Overall, the hydrology of the area is complex and dependent on a variety of factors including precipitation, snowpack, and land use.
