The legislature may provide for the formation of water management districts for the establishment of works of improvement for the drainage of wet, swamp, and overflowed lands of the state, and for flood prevention or the conservation, development, utilization, and disposal of water within the state; confer the right of eminent domain for such purposes, provide for the taxing of the whole or part of the cost of such improvements against the lands and property in such district to the extent of the increased value thereof by reason of special benefits derived from such improvements; and provide for the issuance of bonds for such districts with or without an election; provided, however, that nothing herein shall authorize any such water management districts to engage in or finance, directly or indirectly, the production, transmission or sale of electric power.
