Okla. Stat. tit. 19, § 19-645: Cities and towns of less than 5,000 - Designation as

treasurer - Reimbursement of county - Ordinance - Powers and duties.

The board of trustees, the city council, or the board of city

commissioners of any incorporated town or city having a population

of less than five thousand (5,000) inhabitants according to the last

Federal Decennial Census, shall have the authority to designate the

county treasurer as the official treasurer of such incorporated town

or city having a population of less than five thousand (5,000)

inhabitants according to the last Federal Decennial Census, who

shall serve in such capacity without additional compensation,

provided, however, that the board of trustees, the city council, or

the board of city commissioners shall pay into the general revenue

fund of the county, upon a claim filed by the county clerk an amount

which the board of trustees, the city council, or the board of city

commissioners and the board of county commissioners estimate will

reasonably reimburse the county for supplies which the county

treasurer might need to serve as treasurer of any incorporated town

or city in the state. The designation of the county treasurer as

treasurer of the city or town shall be by ordinance and the voters

of the city or town shall not elect a treasurer while the ordinance

remains in effect. When so designated, the county treasurer shall

exercise all the powers and perform all of the duties of the office

of treasurer of the city or town and his official bond as county

treasurer shall stand for any and all moneys and securities

belonging to the city or town which come into his hands.
