New England Water Use
Background The U.S. Geological Survey has compiled the Nation's water-use data at the county, State, and national levels every 5 years between 1950 and 2015. The most recent estimated water-use compilation was completed in 2015. A summary for New England is presented on this web page. Issue Comprehensive water-use data analysis is needed to quantify the stress on existing supplies, particularly...
The Connecticut Streamflow and Sustainable Water Use Estimator: A Decision-Support Tool to Estimate Streamflow and Water Availability at Ungaged, User-Defined Stream Locations in Connecticut
The Connecticut streamflow and sustainable water use estimator is a decision-support tool that provides estimates of daily unaltered streamflow, water-use adjusted streamflow (for the portions of the state where water-use data are available), and water availability for ungaged, user-defined sites in Connecticut.
