Emiquon Preserve Boat Ramp provides access to Thompson Lake at The Nature Conservancy's 6,000-acre Emiquon Preserve, featuring a concrete boat launch and canoe launch for recreational boating and fishing.

A valid Lake Access Permit and liability waiver (available at Dickson Mounds Museum) are required, and visitors must follow specific regulations including sunrise-to-sunset hours, prohibition of gas motors, and designated fish harvest limits.

The preserve offers excellent wildlife viewing and birding opportunities along with well-maintained visitor facilities including observation decks and hiking trails.
