Wetland Science

It is the policy of the Natural Resources Conservation Service to use the
biological sciences (a) to develop and improve soil and water conservation measures that
help maintain fish and wildlife as integral components of all ecosystems such as
forest, range, cropland, and aquatic ecosystems; (b) to protect the habitat of threatened
and endangered species of plants and animals; (c) to safeguard unique ecosystems; (d) to
develop and maintain an esthetically pleasing, high quality environment.
The information provided below is to assist NRCS, it's partners
and clients with documents that are used for wetland determinations and
compliance issues.

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). Please note that some of
these files are large and may required additional time to load.
