Purpose of Rule

This rule protects the state’s navigable lakes by setting standards for encroachments.

Following Executive Order 2020-01, Zero-Based Regulation this rule chapter is scheduled for a comprehensive review in 2025 with the goal of simplifying the rules for increase clarity and ease of use.
