Ohio Rev. Code § 1546.06
The chief of the division of parks and watercraft shall prepare and submit to the director of natural resources maps and descriptions of the areas of lands and waters which the chief intends to designate as state park purchase areas. Such state park purchase areas may include lands and waters at the time belonging to the state, together with lands and waters not belonging to the state but which for reasons of protection, utilization, and administration should be subject to purchase by the state for park purposes. If such area is approved by the director of natural resources, it shall be known as a state park purchase area, and the map and description thereof, with the approval of the director of natural resources indorsed thereon, shall be filed in duplicate with the director of administrative services and the attorney general.
All moneys appropriated for the purchase of lands and waters by the state for park purposes, unless specifically appropriated for the purchase of particular tracts or areas, may be expended for the purchase of lands or waters within any legally established state park purchase area. If, after the purchase of specifically designated tracts or areas, moneys from such appropriations remain unexpended, upon the request of the director of natural resources, the controlling board shall release such funds, in whole or in part, for the purchase of lands or waters within any state park purchase area.
