SDCL § 46-5-37.2: Exceptions to forfeiture for nonuse.

The provisions of § 46-5-37 notwithstanding, no water right or permit may be forfeited for nonuse if land authorized for irrigation by a permit or right is placed under an acreage reserve or production quota program or otherwise withdrawn from use as required for participation in any federal program, if the water source is not fully appropriated, if the withdrawal from use does not prevent approval of new permits from the same source, and if the appropriated water has been applied to beneficial irrigation use prior to participation in a federal program.
