Okla. Stat. tit. 82, § 82-631: Abandonment of project - Sale of lands and property

In case any such project, or any part thereof, be abandoned as a

flood control project, or in the event any land and property

acquired by purchase or condemnation in fee simple shall no longer

be necessary for the purposes of the district, the same shall not

revert to the former owner or owners or their subsequent grantees of

the property but shall be sold at public sale to the highest bidder

by the board of directors subject to confirmation by the court, with

the proceeds to be paid into the improvement fund created by Section

630 of this title; provided, however, members of the board of

directors and agents, servants and employees of the district shall

have no right to acquire such lands. The former owner shall be

given thirty days (30) notice by certified or registered mail of the

sale, and of his right within ten (10) days after the sale to file

an election with the court to buy the land at the highest bid price.

If the address of such owner is unknown then said notice shall be

given by publication for two (2) consecutive weeks in a newspaper of

general circulation in the county in which the land is located. Such

former owner shall have ten (10) days after such sale to file an

election to take such land at the highest bid price; and unless such

election is filed within said ten-day period, such rights shall

expire and the court shall confirm the sale free of such right. Such

preference right and the requirement that a public sale be held

shall not apply if the sale is made to any agency, department or

instrumentality of the State of Oklahoma; and a district may sell,

transfer or assign property of the district, subject to confirmation

of the court, to the State of Oklahoma or any agency department or

instrumentality thereof by resolution of the board of directors of

said district.

Where lands or interests therein are acquired by the district

and not utilized for the purposes for which it was acquired, or

which have been utilized but such utilization has ceased, then,

after ten (10) years from the date of acquisition, or ten (10) years

from the date utilization ceased, as the case may be, such land must

be sold at public auction to the highest bidder; and mandamus by any

interested party will lie to require such sale.
