Generally revise ground water laws
HB 704 seeks to revise Montana's groundwater laws by establishing temporary "closure" and "monitoring" areas in specific regions. In designated closure areas, including the Gallatin, Helena, Bitterroot, and Missoula Valleys, new groundwater use generally requires a permit, with limited exceptions for small-scale uses like individual homes or stockwater. All new groundwater appropriations in both closure and monitoring areas (such as Flathead and Billings) would require metering and annual reporting of water usage. These provisions are intended to gather data and manage groundwater resources pending a comprehensive study, directly affecting individuals and entities seeking to use groundwater in these regions.

MINOR
The bill was renumbered from LC 4169 to HB 704.1, indicating it has moved from a committee version to a formal House bill. The primary substantive change is the addition of four sponsors (M. Vinton, S. Vinton, S. Fitzpatrick, C. Glimm), which expands the coalition supporting the legislation. The core content of the groundwater law revision remains unchanged, with only formatting and header information updated.
