On April 17, 2025, the Montana Legislature introduced Senate Bill 174, a significant piece of legislation aimed at regulating water rights and subdivision development in the state. The bill seeks to address the complexities surrounding water rights management, particularly in subdivisions where lot sizes average less than five acres.

One of the key provisions of SB 174 mandates that subdividers reserve a portion of the water rights owned by the landowner and transfer these rights to a single entity. This entity would manage water usage for landowners within the subdivision who have legal access to the water. Additionally, the bill requires the establishment of landowner water use agreements to clarify the rights and responsibilities of those entitled to the water.

Another notable aspect of the bill is the requirement for subdividers to create ditch easements within the subdivision. These easements are intended to facilitate the delivery of irrigation water, ensuring that the necessary infrastructure is in place for maintenance and access. However, the bill provides exceptions for subdivisions with average lot sizes of one acre or less, where disclosure to potential buyers about the irrigation status of the land is deemed sufficient.

The introduction of SB 174 has sparked discussions among lawmakers and stakeholders regarding its implications for land development and water resource management in Montana. Proponents argue that the bill will enhance water rights clarity and promote responsible land use, while opponents express concerns about potential restrictions on property development and the administrative burden it may impose on subdividers.

As the legislative process unfolds, experts suggest that the bill could have far-reaching economic and social implications, particularly in areas where water scarcity is a growing concern. The outcome of SB 174 will likely influence future subdivision practices and water management strategies across the state.

The Montana Legislature will continue to review and debate the provisions of SB 174 in the coming weeks, with potential amendments and discussions expected as stakeholders weigh in on the bill's impact on local communities and the environment.
