CONNECTICUT FLOW REPORT

Last Updated: December 25, 2025

Connecticut's river systems are facing varied flow conditions, with many streams experiencing lower than usual streamflow, indicating a potential for flow droughts. For instance, the Housatonic River at Stevenson is reporting a dramatic percent normal decrease at -89.27%, with a current streamflow of just 463 cubic feet per second (cfs) and a minimal 24-hour change. Similarly, the Naugatuck River at Thomaston reveals a significant drop with a -75.92% from the percent normal, registering a flow of 113 cfs. This trend of reduced flow is echoed across major waterways, with the Connecticut River at Thompsonville and the Farmington River at Unionville also reporting streamflow decreases of -71.05% and -71.21% from their normal, respectively, which could influence recreational activities and ecological health.

However, there are anomalies in this pattern, such as the Connecticut River at Middle Haddam, where the current streamflow is a robust 17,100 cfs, although it is at -48.76% from the typical flow, indicating recent higher water levels that may catch the attention of whitewater enthusiasts and signal flood risks in surrounding areas. This river, along with the Salmon River near East Hampton and the Quinebaug River at Jewett City, is a key focus for both the recreational and ecological communities, as these water bodies have considerable influence over regional water dynamics. Gage heights, an indicator of potential flooding, have risen in several areas; the Connecticut River at Thompsonville is currently at 8.46 feet, which could have implications for nearby communities. These trends, marked by significant reductions in streamflow across most rivers and notable exceptions with higher flows, are critical for water management and recreational planning as they may impact river accessibility, fish habitats, and floodplain activities.
