La. Stat. tit. 17 § 97.1
No proceeds derived from the sale, lease, or other disposition or use of any sixteenth section lands by a parish or city school board, no allocation of severance taxes, if any, to a parish or city school board, or school system and no portion of the proceeds derived from any sales tax levied and collected by a parish or city school board shall be used or taken into consideration in any formula adopted by the Louisiana State Board of Elementary and Secondary Education and submitted to the legislature for approval as required by Article VIII, Section 13(B) of the Constitution for the allocation of funds to insure a minimum foundation program of education in all public elementary and secondary schools.
Funds derived from the sale, lease, or use of sixteenth section lands heretofore charged against school systems in the minimum foundation program formula shall be replaced by equal amounts from revenues generated by lease or royalties of sixteenth section water bottoms claimed by the State; provided, however, that in the event such replacement revenues are insufficient for such purpose then, and in that event only, revenues generated by lease or royalties from other water bottoms claimed by the state shall be used as needed for the purposes of this Section.
