Bottom Moose Put-in provides access to one of the most challenging whitewater runs in the Northeast, featuring Class IV-V rapids including Fowlersville Falls and multiple technical drops.

The put-in is located upstream of Fowlersville Falls on Fowlersville Road near Lyons Falls, with parking available at the bridge; boaters should note that scheduled water releases occur in May and October, and all paddlers must sign in at the power station office before accessing the river.

This expert-only run requires advanced whitewater kayaking skills and is best tackled during release weekends when adequate water flow is guaranteed.
