If a river or stream, whether navigable or not, opens itself a new bed by leaving its former channel, the owners of the soil newly occupied shall take, by way of indemnification, the former bed of the river, everyone in proportion to the quantity of land he has lost.\nThe said owners shall have the right to their former property if the river or stream returns to its former channel.\nHistory —Civil Code, 1930, § 306.
