Niangua River
Float Trip Guide.

Upper Niangua — above Bennett Spring

Above Bennett Spring the river is smaller and rain-dependent. Pretty, quiet half-day water from Moon Valley toward the spring, but it can get low in summer before Bennett's flow joins.

Bennett Spring to Prosperine — the outfitted heart

Below Bennett Spring's ~100 million gallons a day the Niangua runs cold, clear, and reliable. This is the busy, beginner-friendly stretch where nearly every outfitter and riverside campground sits.

Lower Niangua — Prosperine to Tunnel Dam

Quieter water past limestone bluffs toward the historic Tunnel Dam and the Lake of the Ozarks. Fewer people and good smallmouth fishing — but know your take-out: the lower river ends at a hydroelectric diversion dam.

• PFDs (legally required — one per person, worn by anyone under 7).
• Dry bag for keys, phone, ID, and a layer — the spring water is cold.
• Drinking water (a gallon per person per day in summer) — there's no potable water on the river.
• Reef-safe sunscreen and a hat.
• Hard-soled water shoes for rocky gravel bars.
• A plan for your lower-river take-out if you're floating toward Tunnel Dam.
• Trash bag — pack out everything you bring in.

• Reliable when others are low. Bennett Spring's base flow keeps the Niangua floatable when the Meramec, Huzzah, and Jacks Fork have dropped too low. A smart summer fallback.
• Take out above Tunnel Dam. The lower river runs to a privately owned hydroelectric diversion dam near mile 66. Take out at the marked access; never approach the dam.
• Base at Bennett Spring. Most outfitters, rentals, and riverside campgrounds cluster between Bennett Spring and Prosperine — the easiest place to set up a first trip.
• Mind the trout water up top. Bennett Spring State Park is a busy trout park; the cold park water is fly- and tag-only and separate from the float zone.
