Okla. Stat. tit. 82, § 82-547

Districts may be formed under the provisions of this act for

irrigation, or partly for irrigation, by a substantial compliance

with the terms as near as possible. But no such 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 their protective value. And the court

organizing such irrigation district shall require a statement in the

petition and proof to the effect that the organization and operation

of the same will not materially interfere with any work or plans for

flood prevention, the drainage or protection of lands, or the flow

of waters covered by the terms of a contract. Nor shall any

improvement under this act deprive the owners of lands lying upon

any stream of water of the ordinary flow in said stream sufficient

for domestic and stock uses, without compensation therefor.

Subject to the above, the board of directors shall have the same

powers as are herein conferred generally by its provisions as far as

applicable.

Special assessments shall be levied and bonds issued as already

provided, using the words "Conservancy Special Assessments," or

"Conservancy Bonds."
