Revise exempt water right laws

This bill revises Montana's ground water laws by clarifying when permits are required and updating rules for water rights. It directly affects landowners, water users, and local fire agencies by modifying the process for appropriating groundwater outside of controlled areas. Key changes include allowing local fire agencies to use groundwater for emergency purposes without permits, requiring water users to notify landowners 30 days before construction, and mandating measuring devices on facilities in chronically dewatered watercourses. The bill also gives the Department of Natural Resources broader authority to set fees and adopt rules for well construction, monitoring, and temporary emergency appropriations.
