Objectives Develop an easy-to-use, screening-level tool to estimate continuous
unimpacted streamflow at ungaged locations in the Connecticut River basin (excluding the mainstem of the Connecticut River)
POINT-AND-CLICK GIS USER-INTERFACE COUPLED WITH
MICROSOFT EXCEL SPREADSHEET
APPROACH REQUIRES SIMPLIFYING ASSUMPTIONS AND
FEW PARAMETERS
Existing tools to estimate daily, unregulated and water-use adjusted streamflow in southern New England had already been developed [Archfield et al., 2010 and Archfield and Vogel, 2010] (aka MA SYE)
This project leverages these existing methods to create the CRUISE tool, which provides estimates of daily, unregulated streamflow across the entire Connecticut River Basin.
The Connecticut River UnImpacted Streamflow Estimation (CRUISE) tool

The Connecticut River Basin UnImpacted Flows tool
Locate and select stream reach of interest
Begin with an overview of the entire basin

The Connecticut River Basin Unimpacted Flows Tool
The user can export a shapefile of the delineated basin and obtain the
basin characteristics needed to calculate daily streamflow
Basin is delineated
Basin characteristics are computed and summarized
The spreadsheet program uses the basin characteristics to complete the calculation of daily streamflow
This process balances the flexibility needed to customize the tool to meet the user needs while removing the complex
desktop setup process and problems encountered due to version control.

Application of the CRUISE tool The CRUISE tool was applied to
approximately 300 stream locations in the Connecticut River Basin.
These locations were dam locations and/or nodes of ecological interest.
Streamflow data at these nodes are being used in simulation and optimization models of the basin.
Streamflow data is available through the Army Corps of Engineers DSS software
