Work from this project allows users to identify a stream reach of interest in the Connecticut River basin and obtain estimated continuous daily, unregulated or “natural” streamflow at the selected location. The application spans the entire Connecticut River basin, including the states of Connecticut, Massachusetts, New Hampshire and Vermont. This work expands on a method developed for Massachusetts to estimate daily streamflows at ungaged locations. The project is divided into two tasks: 1) the refinement of the methods to include gages in the northern portion of the Connecticut River Basin, and 2) the development of a seamless, multi-state point-and-click GIS application to interactively estimate streamflow at ungaged locations in the Connecticut River Basin.  This project integrates current work being completed in cooperation with the Massachusetts Department of Environmental Protection and the Connecticut Department of Environmental Protection.

UPDATES (April 2012)

To date, all project work has been completed. The development of the multi-state tool is complete; the software tool and user manual has been published on the publically-available website: http://webdmamrl.er.usgs.gov/s1/sarch/ctrtool/index.html. The manuscript has been published in the international journal Geoscientific Model Development and can be downloaded for free here and is available below. The report describes the software tool and functionality as well as the underlying methods and the utility of the software tool to estimate daily streamflow at ungauged locations in the Connecticut River Basin. A powerpoint presented in an April webinar discussing the software is available here.
