Wetland Determinations Aid - 7 and 15 Day Flood Data/Profiles
Tabular data and stream profiles that are provided for flooding where durations are sustained for periods of 7 and 15 consecutive days, at least once every two years (50% chance), during the growing season. Information should be used within a stream floodplain or riverine area in considering the potential for flooding to enhance or impact hydric soils and/or tree plantings in connection with programs falling within the USDA-NRCS Wetland Reserve Program (WRP) and Wetlands Reserve Enhancement Program (WREP).
