Headwaters Access provides boat ramp access to the Castor River Diversion Channel, which connects to the Mississippi River near Cape Girardeau.

The facility features an expanded concrete parking lot with 33 spaces and an improved boat ramp designed for easier launching and landing.

Water access depends on river levels—the ramp is accessible when the Cape Girardeau gauge is between 6-8 feet, though higher water stages can flood the parking area.
