Regression equations to estimate selected peak-flow frequencies at ungaged streams was added to Connecticut StreamStats March 2021. The regional regression equations were derived from statistical analyses of peak-flow data and basin characteristics for 85 streamgages, incorporated a newly developed regional skew coefficient for New England, and followed guidelines for flood frequency analysis described in Bulletin 17C (link). Documentation for the development of the regression equations can be found in the associated Scientific Investigation Report (https://doi.org/10.3133/sir20205054). General information about the Connecticut StreamStats application, computed streamgage statistics, and methods for estimating streamflow statistics at ungaged locations can be at the through the information icon in StreamStats as well as the direct links for  Application page (https://streamstats.freshdesk.com/support/solutions/articles/9000054084-connecticut) and Application Information (https://streamstats.freshdesk.com/support/solutions/articles/9000055574-connecticutpage).
