Graphical representation of flood inundation for NWS flood categories are based on steady state hydraulic modeling of water surface elevations for incremented discharges. Map shows approximate inundation areas for given water surface elevations and should not be used for navigation or permitting or other legal purposes, but strictly as a planning reference tool.

428 There will be widespread devastating flooding in and around Waterbury. Homes and businesses on lower elevations of Main Street will flood, along with Elm Street, Parker Court, Park Row, and Randall Streets. Areas along Graves Brook will flood as it approaches Rowe Park. Water will approach lower level parking of the State Office complex. There will be extensive flooding downstream in Richmond. This stage is equivalent to the FEMA 1 Percent Annual Chance Flood.
