Okla. Stat. tit. 11, § 11-37-103

A. The municipal governing body may dam any river or stream

which is not navigable, and condemn, appropriate and divert the

water from such river or stream, or so much thereof, as may be

deemed necessary; and may condemn and appropriate in the name of and

for the use of the municipality any land located in or outside of

the corporate limits of the municipality as may be necessary for the

construction and operation of waterworks. The appropriation of land

or of water rights by any municipality shall be governed by the

procedure prescribed for the condemnation of land for railway

purposes. The water and the right to divert the water may be

described, at the option of the municipality, in capacity by a given

number of gallons daily, or as a quantity sufficient for the

purposes. Upon the payment made or deposit of the award of the

commissioners to the clerk of the district court, the municipality

shall be vested with the perpetual right to use the land so

condemned and the right to divert the water so condemned for the

purposes mentioned herein. The exercise of this power shall be a

continuing right and not exhausted by one or more exercises thereof.

B. The provisions of this section and Sections 37-104 and 37-105 of

this title shall be construed as cumulative to the rights and powers

already possessed by municipalities to purchase, take and condemn

land for public uses.
