Okla. Stat. tit. 82, § 82-1020.5: Determination of maximum annual yield

A. After completing the hydrologic survey, the Board shall make

a tentative determination of the maximum annual yield of groundwater

to be produced from each ground water basin or subbasin therein.

Such determination must be based upon the following:

1. The total land area overlying the basin or subbasin;

2. The amount of water in storage in the basin or subbasin;

3. The rate of recharge to the basin or subbasin and total

discharge from the basin or subbasin;

4. Transmissibility of the basin or subbasin; and

5. The possibility of pollution of the basin or subbasin from

natural sources.

B. The maximum annual yield of each major ground water basin or

subbasin shall be based upon a minimum basin or subbasin life of

twenty (20) years from the effective date of the order establishing

the final determination of the maximum annual yield.

C. For minor groundwater basins or subbasins therein, the

tentative determination of the maximum annual yield shall be based

upon present and reasonably foreseeable future use of groundwater

from such basin or subbasin, recharge and total discharge, the

geographical region in which the basin or subbasin is located and

other relevant factors.
