SB 357 Montana Senate · 2025 Regular Session

Extend perfection deadline for certain Missouri River water reservations

Senate Bill 357 extends a deadline for the "perfection" of certain water reservations. This means it provides more time for entities, such as the state, political subdivisions, or U.S. agencies, to finalize their claims for specific water rights. The bill primarily affects those with water reservations on the Missouri River located above the Fort Peck Dam. It amends existing state law to implement this extension and also grants authority for the development of related rules.

MODERATE
The bill amends the Montana Water Code to clarify the legal definition of state water reservations, specifically addressing the Fort Peck Dam and out-of-state water transport. It updates the statutory text to ensure consistency with current legislative formatting and explicitly confirms that state water reservations issued for maintaining minimum flows are considered complete upon issuance, rather than requiring physical construction.
Scope change
The scope of the bill remains focused on water rights administration, but the amendment clarifies the legal status of 'maintenance' reservations and standardizes the application process for state water reservations.
DEFINITION

The text was updated to align with the official title of the bill, clarifying that the act extends deadlines for water reservations above Fort Peck Dam and provides rulemaking authority.

REQUIREMENT

The statutory language regarding the issuance of state water reservations was reorganized and slightly reworded to improve clarity on the evidence required for approval and the factors considered for out-of-state transport.

A specific provision was added confirming that water appropriations for maintaining minimum flow, level, or quality are legally complete immediately upon the department issuing the reservation, removing ambiguity about when the right is perfected.

TECHNICAL

Minor formatting changes were made to standardize the layout, numbering, and capitalization of the statute to match the official enrolled bill format.
