Flood Plain Information, Connecticut River, West River and Whetstone Brook, Brattleboro, Vermont.

This report covers in general, two phases of the flood situation along the Connecticut River, West River, and Whetstone Brook. The first phase relates to past floods in the area. The second phase discusses the probability of future floods of various magnitudes including the Intermediate Regional Flood and the Standard Project Flood. These flood magnitudes are determined from an analysis of past floods on the Connecticut and West Rivers and of floods on streams which have hydraulic characteristics similar to Whetstone Brook and are in the same general physiographic and geographic region. The Standard Project Flood is rare and on most streams is considered larger than any flood that has occurred in the past. However, a flood of this magnitude should be considered in planning for use of the flood plain. Maps and profiles which show the extent of flooding that might occur in the future in the Brattleboro area along with high-water marks of past floods are included in this report. From these, the depth of probable flooding at any location may be estimated. The report is intended to provide the basis for further study and planning on the part of the Town of Brattleboro in arriving at solutions to minimize vulnerability to flood damage.
