Abstract:

This report presents hydrologic information and analysis relative to flood problems on Beaver Brook located in the Ashuelot River watershed in Keene, New Hampshire. The study was performed under authority contained in Section 205 of the 1948 Flood Control Act and analysis was directed specifically to flooding on Beaver Brook in the reach approximately 1,800 feet in length between Marlboro and Water Streets. Also investigated were modifications to the outlet at the upstream Three Mile Swamp for purposes of increased flood control storage. Included are sections on watershed description, general climatology, flood history and frequencies, standard project flood, flood profiles, and plans of improvement. Beaver Brook flooding has been the subject of several past studies. Earlier studies by the Corps of Engineers lead to Congressional authorization in 1968 of Beaver Brook Lake, a multipurpose water supply and flood control dam and reservoir. However, due to escalating costs and lack of local support the project was not constructed. Current studies reported herein, dealt with the hydrologic analysis of selected small scale structural improvements for inclusion, if feasible, in a primarily nonstructural flood control plan for the city of Keene. The token improvements analyzed were identified in a nonstructual flood damage reduction report completed in 1980 for the city of Keene.
