Idaho Code § 67-4201
Wherever any lands are owned by the state of Idaho, bordering on or in the vicinity of any lake, waterfall, spring or other natural curiosity, the park and recreation board of the department of parks and recreation may withdraw the premises from sale. If in the opinion of the park and recreation board it is desirable, the lands may be platted into lots and blocks, parks, streets and public places, and the lots and blocks may be appraised and an annual rental fixed thereon. No lease of the premises shall be made for a longer period than ten (10) years, and every lease shall specify that no disorderly house shall be kept on the premises; that the premises shall be kept in good condition, and that no waste shall be committed thereon. Notwithstanding the foregoing, the board may, in its discretion, extend or renew an existing lease of a float home moorage site for a period of up to thirty (30) years, on terms and conditions as the board deems appropriate. The board may require a bond against waste, and may prescribe additional rules for leasing of the premises for the use thereof and for construction of buildings or other improvements thereon, and the removal thereof.
