The single most useful skill in Ozark paddling is knowing, before you load the car, whether your river actually has water. Our rivers are mostly rain-fed and free-flowing, so a creek that was perfect last weekend can be a gravel hike today. Here's how to read the water - the way this site does it, and the tricks for the spots we can't measure directly.
Live USGS gauges (CFS and feet).
Most of our rivers have a U.S. Geological Survey gauge in the water, reporting two numbers every 15 minutes. This site reads them live.
CFS - cubic feet per second
How much water is moving past the gauge. It's the best single number for floatability. Each river has an ideal CFS range: too little and you scrape gravel; too much and it runs fast and pushy. Our color badges turn that range into Too Low, Good to Float, High / Fast, and Flood.
Gauge height - feet
How deep the water is at the gauge's own marker. It's a local number - 4 feet on the Kings is not 4 feet on War Eagle - so it's useful per-river (and it's how most outfitters talk), but CFS is the number that compares across rivers. We show both.
Proxy gauges & rainfall.
Plenty of good creeks have no gauge in them. You can still read them - you just borrow a number from nearby.
Borrow an upstream or nearby gauge
Find a USGS gauge in the same watershed - upstream on the same creek, or on a neighbor that drains the same hills - and assume your ungauged creek is doing something similar. It won't be the exact CFS (the drainages differ), but the rise-and-fall tracks closely, especially right after rain. We already do this on the site: Big Sugar Creek is read off the neighboring Indian Creek gauge.
Watch the last 24-48 hours of rain
Flashy creeks live and die by recent rain. No rain in a week? The little creeks are bony. A two-inch overnight soaking? They're up - and dropping fast, so go soon. Pair a rain-radar app with the nearest gauge's trend (rising or falling) for the full picture.
Spring-fed, dam-controlled & lakes.
Some water ignores the forecast entirely - handy to know when everything else is too low.
Spring-fed streams
Fed by big constant springs, these run clear and cold year-round no matter the rain. Roaring River (Cassville, MO) pours from a state-park spring; the Spring River at Mammoth Spring/Hardy is a famous year-round float (it's gauged at Hardy, but it's a 2.5-3 hour drive - a worth-it outlier).
Dam-controlled tailwaters
The White River below Beaver Dam runs cold and steady on the Corps' release schedule rather than the weather - reliable, if chilly, water.
Lakes don't need a gauge at all
Small no-motor lakes are the same friendly flatwater every day of the year - the rain-proof answer when the rivers read "Too Low." The big reservoirs (Beaver, Table Rock) publish pool elevation through the U.S. Army Corps of Engineers if you ever need it. See the lakes guide →
Outfitter gauges & a phone call.
The people who run a river every day are the best gauge of all.
Many outfitters post their own staff-gauge reading and a plain-English difficulty chart - Turner Bend on the Mulberry, for instance, publishes a feet-by-feet table from "too low" to "too much water." And nothing beats a quick call: an outfitter will tell you straight whether it's worth the drive today, which boats are running, and what the water's been doing. When in doubt, call ahead.
Floatable, but no live number - and how to read them.
A handful of genuinely good runs near NWA have no gauge of their own. They're not on our live levels for that reason - but here's how to know when they're up. Most are flashy or expert water; check the proxy gauge and recent rain, and when in doubt, don't.
A genuine floatable Buffalo tributary with no live discharge gauge. Read it off the nearby Buffalo at Ponca in the same watershed - if the upper Buffalo is up after rain, the Little Buffalo usually is too. Spring and after-rain only.
Steep Class III-IV expert whitewater with no live CFS feed. Paddlers read it off the Richland Creek gauge next door - if Richland is running, Falling Water likely is too. Experts only, after heavy rain.
Tiny Buffalo headwater creeks that only run briefly after a big rain. Read them off the Buffalo at Boxley / Ponca and a fresh radar check. High-water windows close fast.
A small spring-season run near Devil's Den with no gauge at the float reach. Read it off Lee Creek-area levels and recent rain; it's in and out quickly.
Proxy gauges show the trend, not the exact flow - the ungauged creek will read differently than its neighbor. Treat these as "is it worth a look" signals, scout on arrival, and never paddle expert water beyond your skill or in rising flood conditions.
