The Legislature shall not pass any law authorizing nor shall any officer, agency, or employee transfer, use, or pledge any monies from the State Parks Fund, the Parks Revolving Fund, or any fund receiving revenues currently deposited in the State Parks Fund or the Parks Revolving Fund, and any monies currently designated by law and deposited into a public account for the use by the state parks system from being transferred to any other public account, fund or entity or used for any purpose other than the support, upkeep, and maintenance of the state parks system.

Notwithstanding, in the event that guest revenues to the State Parks Revolving Fund exceed the threshold of $50 million (as annually adjusted based on increases in the consumer price index) in a fiscal year, the sales and use and cigarette tax revenue distributed to benefit the State Parks System shall be reduced in the following fiscal year. The amount of the reduction shall correspond to the amount of guest revenue to the State Parks Revolving Fund exceeding the threshold. The amount of tax revenue not distributed to benefit the State Parks System shall be distributed to the General Fund.
