06 / Boating & fishingGuides & regulations.

Wake Boat Guidance

Grace Lake Recommended Wake Boat Area

Wake surfing and wake boating should be done in water at least 20 feet deep and at least 500 feet from shore. This minimizes shoreline erosion, sediment disturbance, and property impacts. The map was purchased through Minnesota Lakes & Rivers Association and shows the recommended area for Grace Lake — the purple zone covers the central deeper water.

Large wakes produced at certain speeds can cause shoreline erosion, impair water quality, damage docked boats, and create safety hazards. You are responsible for your wake.
