This bill aims to modify the process of updating and revising the public water inventory in Minnesota. Key aspects of the bill include:

1. Updating Public Water Maps: The bill requires the commissioner to maintain and update county maps showing public waters. These maps must be available to county auditors when revisions occur.

2. Reclassifying Wetlands: Special focus is on changing the classification of certain wetlands (types 3, 4, and 5) that were previously marked as public waters wetlands. They can only be reclassified as public waters if they meet specific criteria such as being in shoreland management areas, being identified as lacustrine wetlands or deepwater habitats, or if the government owns the land and deems it necessary for public use.

3. Notifying and Objecting: If there are changes or reclassifications, the commissioner must notify local government units and relevant conservation districts. These entities have 60 days to object to the changes, and if objections are received, the changes do not become effective.

4. Prioritizing Reclassifications: Preference is given to reclassifying wetlands that could impact public works projects.

5. Additional Map Revisions: Aside from reclassifying wetlands, the commissioner can adjust the maps to correct mistakes, account for changes in trout stream tributaries, and add or remove certain large water bodies or public waters affected by permits.

6. Funding: The bill appropriates $1,000,000 annually from 2025 to 2032 to support these activities.

Overall, the bill sets out to improve the accuracy and relevance of public water classifications and maps in Minnesota, enhancing environmental management and preserving natural resources.
