Revise laws related to considerations for measuring of streamflow
SB 61 updates Montana's water policy to require accurate, real-time streamflow measurement for determining water availability. It affects water rights holders and state water managers by ensuring new water uses can only be approved when legally and physically available, protecting existing rights. The bill integrates these measurement standards into Montana's existing water law framework under Title 85. This policy change aims to improve the accuracy of water distribution decisions.

MINOR
The bill text shows minor formatting and punctuation adjustments rather than substantive policy changes. The title line was slightly modified by removing a period at the end, and the document was restructured with the committee request moved to a different location. These appear to be administrative edits for consistency in the final version.
TECHNICAL
Minor punctuation adjustment removed a period at the end of the act title line.
Document structure was reorganized with the Water Policy Interim Committee request moved to a different position in the text.
