The Charlotte River is a tributary of the St. Marys River, which forms the border between Michigan's Upper Peninsula and Ontario, Canada, and connects Lake Superior to Lake Huron. The ramp at the Charlotte's mouth provides direct access to the St. Marys — a major Great Lakes shipping corridor and fishery. The launch is near the Sugar Island ferry crossing.
The Charlotte River is a shallow, flowing waterway — river current means ice conditions can be unpredictable and unsafe even in cold weather. The St. Marys River, which it feeds, also has areas of current and shipping traffic that affect ice quality. Exercise extreme caution.

The Charlotte River is a small tributary of the St. Marys River in Chippewa County — more river than lake, and used primarily as a launch point to access the St. Marys. The single boat ramp sits right in the river current near where it empties into the St. Marys, which means sand buildup and erosion are ongoing issues at the ramp. The mouth of the Charlotte is close enough to the shipping channel that freighters passing on the St. Marys create a dramatic tidal-bore effect — water pulls out of the Charlotte and then rushes back in as the ship passes. It's genuinely impressive to watch.
Locals use the ramp area as a fishing spot while waiting for the Sugar Island ferry, casting from the banks near Dunbar Park. The park is also a solid birdwatching spot. Upstream, the river splits into two branches — one rocky, one choked with fallen trees — making it an interesting kayak exploration if you don't mind navigating deadfall. This isn't a destination lake; it's a functional access point to the St. Marys River system and a quirky little spot with character.
