WATER SUPPLY BANK – Amends existing law to provide that the forfeiture period restarts upon removal of a water right from the water supply bank.

This Idaho bill (S 1084) amends water rights law to clarify how the five-year nonuse forfeiture period works for rights held in the state's Water Supply Bank. It directly affects water rights owners who temporarily place their rights into the bank. The key change states that if a water right was not already subject to a nonuse period before being added to the bank, the five-year forfeiture clock restarts when the owner removes the right from the bank. If the right had an existing nonuse period before entering the bank, that period continues uninterrupted. The bill takes effect July 1, 2025.
