The Indiana Department of Natural Resources regulates the use and diversion of surface waters. An entity that creates additional stream volumes by releases from impoundments built and financed by the entity for the entity's purpose may use the increased flowage at all times. Any entity may be required to report the volume of water used. Diversion of water out of the Great Lakes Basin is subject to permitting regulations, and may not occur except under the Great Lakes/St. Lawrence River Basin Water Resources Compact.
