Ohio Rev. Code § 6101.73
Irrigation districts may be formed under this chapter by a substantial compliance as near as possible with its provisions. No irrigation district in its construction or operation shall, in any manner, interfere with works for the prevention of floods or the drainage of lands or materially diminish the works' protective value. The court organizing the irrigation district shall require a statement in the petition and proof to the effect that the organization and operation of the irrigation district will not materially interfere with any works or plans for flood prevention or the drainage or protection of lands. No improvement under this chapter shall deprive the owners of lands lying upon any stream of water of the ordinary flow in the stream without compensation.
Subject to this section, the board of directors has the same powers as are conferred generally by this chapter insofar as applicable.
Assessments shall be levied and bonds issued as provided in this chapter, using the words "Conservancy Assessments" or "Conservancy Bonds."
