Okla. Stat. tit. 11, § 11-37-127: Municipalities outside Oklahoma - Purchase of lands for

water in Oklahoma.

An incorporated municipality of a state adjoining the State of

Oklahoma is hereby granted permission, if authorized or empowered by

the laws of such adjoining state to do so, to acquire by purchase

from a private corporation which may be furnishing water to water

users in the municipality, or which may be furnishing water to the

municipality for resale to water users therein, the title to, or

lesser interest in, lands that the private corporation owns in the

State of Oklahoma. The municipality may also acquire any easements

or rights-of-way then owned by such corporation over and across

other lands within the State of Oklahoma necessary for pipelines to

convey water from a reservoir to a point or points outside the State

of Oklahoma. Such lands, easements and rights-of-way acquired by

the municipality may be used in connection with, but only used in

connection with, the establishment, betterment or expansion of a

municipally-owned water supply or system; the necessary protection

of the water supply from pollution; or the maintenance and operation

of the municipally-owned water supply or system. The municipality

may continue to hold lands, easements and rights-of-way so acquired

as long as the same are so used. In order to transfer or convey any

of its interests in Oklahoma lands, the private corporation shall

have owned the title to, or any lesser interest in, lands within the

State of Oklahoma as of April 25, 1957, upon which is located, in

whole or in part, a reservoir from which such water or portion

thereof is obtained, which reservoir has been in existence on the

lands for more than one (1) year prior to April 25, 1957, and which

land, or interest therein, has been owned by the corporation for

more than fifteen (15) years prior to April 25, 1957.
