Montana's House Bill 681, introduced on April 18, 2025, aims to streamline water rights management for appropriators who have historically used groundwater without formal documentation. The bill addresses a significant gap in water rights regulation, particularly for those who began using groundwater between January 1, 1962, and July 1, 1973, but failed to file a notice of completion as required by earlier laws.

Key provisions of HB 681 allow these appropriators to file a notice of completion with the state’s Department of Natural Resources and Conservation, thereby perfecting their water rights. This filing will establish a priority date based on when the notice is submitted, ensuring that these users are recognized legally. Notably, if the appropriation involves less than 35 gallons per minute or does not exceed 10 acre-feet annually, the department will issue a certificate of water right, simplifying the process for smaller users.

The bill also eliminates the need for permits for constructing small impoundments or pits for livestock water, provided certain conditions are met, such as the capacity being under 15 acre-feet and the land being at least 40 acres. This provision is expected to ease the regulatory burden on ranchers and farmers, promoting agricultural sustainability in the region.

Debate surrounding HB 681 has centered on its potential impact on existing water rights holders. Critics express concerns that easing regulations could lead to over-appropriation of water resources, particularly in areas already facing water scarcity. Proponents argue that the bill is essential for recognizing the rights of long-time users and supporting agricultural practices.

The implications of HB 681 extend beyond legal recognition; it could significantly affect Montana's agricultural economy by providing more straightforward access to water resources for livestock and crop irrigation. As the state grapples with ongoing drought conditions, the bill's passage could be pivotal in balancing the needs of agricultural stakeholders with environmental conservation efforts.

As the legislative process unfolds, stakeholders will be closely monitoring the bill's progress and its potential to reshape water rights management in Montana. The outcome could set a precedent for how water resources are allocated and managed in the future, highlighting the ongoing tension between development and conservation in the state.
