Flood of April 2007 and Flood-Frequency Estimates at Streamflow-Gaging Stations in Western Connecticut [open pdf - 3MB]
"The study area in western Connecticut-primarily Fairfield and Litchfield Counties--includes 28 active streamflow-gaging stations for reporting peak stages and peak discharges (fig. 1 and table 1). The data collected and analyzed from this storm enhance the scientific understanding of flood characteristics and are critical for reducing deaths, injuries, and property damages from floods. Current estimates of the magnitude and frequency of floods provide key information for updating Flood Insurance Studies, mitigating losses associated with future floods, and designing bridges and culverts. This report includes information on rainfall that led to the flooding, peak stages and peak discharges for the April 2007 flood for rivers with active streamflow-gaging stations, and updated flood-frequency estimates for streamflow-gaging stations in western Connecticut. Also included in this report is a comparison of flood-frequency estimates using (1) reported data through water year 2007 (ending September 30, 2007) to (2) flood-frequency estimates in community Flood Insurance Studies prepared for communities by FEMA [Federal Emergency Management Agency]. The changes in flood stages at the stations attributed to changes in the recurrence interval values are described."
