This launch sits on Little Thunder (West Bay); look for other public access points, marinas and shoreline fishing spots along the same water, and check the Minnesota DNR for the full list of access sites nearby.

The bay offers shelter, but it is shallow in places and the open mouth can pick up wind and chop. Mind your prop in the shallows and follow marked channels.

Carry U.S. Coast Guard–required safety gear, wear your life jacket, file a float plan for longer trips, and remember that spring and fall water is cold enough to cause hypothermia quickly.

A Minnesota fishing license is required for anglers 16 and older. Follow the Minnesota DNR's seasons, size and creel limits, which vary by water and species.

Clean, Drain and Dry: remove all aquatic plants and animals, drain every compartment, and never move live fish or bait between waters — this is how invasive species like zebra mussels and invasive carp spread.

Observe posted launch rules, no-wake and idle zones near the ramp, and any local watercraft controls.

Stage your gear before backing down to keep the lanes moving, especially on busy mornings. Check the ramp depth for your boat's draft, and rig the trailer lights to handle a dunk.

Arrive early on summer weekends for parking, and have a plan for wind direction before you launch on open water.
