What is the floodway?

The Floodway is defined in IC 14-8-2-102 as:

  1. The channel of a river or stream; and
  2. The parts of the floodplain adjoining the channel that are reasonably required to efficiently carry and discharge the flood water or flood flow of a river or stream

Requirements for the floodway portion of the floodplain:
The DNR Division of Water has jurisdiction in Indiana's floodways for most development activities. Typical examples of floodway projects subject to DNR review and approval are fills, excavations, bridges, utilities, and non-residential structures. See the Statutes/Rules section for specific information on the DNR's permitting jurisdiction.
