HB580

Clarify water right abandonment

Complete·5/8/25

Montana HB580 clarifies water right abandonment laws to protect rights during droughts.

Montana HB580 amends water right abandonment laws to ensure that a reduction in use or nonuse of an appropriation right during droughts does not automatically constitute abandonment. The bill specifies that nonuse does not represent abandonment if it occurs due to a conservation set-aside program, drought conditions, or compliance with a drought plan. It also clarifies that temporary changes in appropriation rights or leases do not create a presumption of abandonment. The changes apply to existing rights once they are finally determined.
