Okla. Stat. tit. 11, § 11-37-104: Acquiring lands - Protection from contamination

Any municipality may purchase or condemn and hold the perpetual

right to use any lots or lands, either within or without the

corporate limits of the municipality, which the municipal governing

body determines by resolution to be necessary for acquisition by the

municipality in order to locate and build or enlarge, at the time or

in the future, waterworks and every auxiliary part thereof,

including reservoir site or sites to be flooded, and the lands

adjacent thereto and within six hundred sixty (660) feet of the

margin of the reservoir at maximum high water. The governing body

may protect from possible contamination or pollution and police any

such lands in order to protect any reservoir already constructed or

proposed to be constructed or enlarged as a part of any municipal

waterworks plant or water supply, the waters thereof, and the waters

flowing therein or percolating or seeping thereto. The property and

land so acquired before and after the passage of this subarticle,

insofar as such lands are within six hundred sixty (660) feet of the

margin of a reservoir at maximum high water and necessary for

natural drainage into the reservoir, shall not be used by the

municipality, its lessees or assigns, or other persons or

corporations, for any purpose other than the protection of the

reservoir and the waters thereof from contamination and pollution.

No structures shall be placed on such lands by the municipality,

individual or corporation, except as are necessary in the

furtherance of the protection of the reservoir from contamination or

pollution, and in the use of the water.
