Eddy reads the gauge, the trend, and the forecast and writes a fresh take a few times a day. Use it as one input alongside your own judgment, the outfitter you’re renting from, and the most recent NPS advisories.
Why the Meramec is different
The Meramec is St. Louis's home float. One of the longest free-flowing rivers in Missouri, it runs about 90 minutes down I-44 to the outfitter towns of Steelville and Sullivan — the closest quality float water to the city. It's rain-fed, not spring-fed, which makes it one of the flashiest rivers in the Ozarks: gorgeous and lively when the water's up, and unlike the Current, never guaranteed to be floatable just because it's summer.
- Closest quality float to St. Louis. About 90 minutes to Steelville or Sullivan on I-44. No other Ozark float this good is this close to the metro.
- Caves everywhere. Onondaga Cave and Meramec Caverns are show caves right on the river, and Fisher Cave runs lantern tours from Meramec State Park. The bluffs are riddled with them.
- Rain-fed and flashy. The Meramec can spike 5–10 feet in hours after a hard rain and drop fast in a dry spell. There's no spring base flow to fall back on — the gauge is everything.
- Three rivers in one. A narrow, trout-tinged upper river; a bluff-and-cave middle that's the prettiest water; and a wide, gentle lower river built for tubes and big groups.
Pick your float
The Meramec divides cleanly into character zones. Pick by how much time you have, who you’re paddling with, and what you want to see.
Upper Meramec — Maramec Spring to Onondaga
The headwaters reach near St. James and Steelville: narrower, scenic, and trout-tinged. The Woodson K. Woods-to-Scotts Ford stretch is a Red Ribbon Trout Area. Needs more water than the lower river, and rewards it with solitude and bluffs.
Middle Meramec — Onondaga to Meramec State Park
The finest water on the river: about 20 miles of towering limestone bluffs, cave mouths, springs, and wide gravel bars. Most Steelville-area outfitters run this stretch, with 5- and 9-mile options.
Lower Meramec — the park to the metro
Below Meramec State Park the river widens and gentles. The Meramec Caverns stretch draws big summer tube crowds; farther down toward Robertsville and Eureka it's a quieter, wider metro-edge paddle.

Water levels & gauge
Check the gauge before you load the truck. The trend over the last week matters more than today’s number — a falling river after a flood is fine; a rising river isn’t.

Before you launch & on the water
- PFDs (legally required — one per person, worn by anyone under 7).
- Dry bag for keys, phone, ID, and a layer. Riffles flip beginners.
- Drinking water (a gallon per person per day in summer) — there's no potable water on the river.
- Reef-safe sunscreen and a hat — the lower river has long, shadeless stretches.
- Hard-soled water shoes, not flip-flops. Gravel bars are rocky.
- A cooler tied securely into the boat.
- Trash bag — the Meramec sees heavy use; pack out everything.
- It's rain-fed — check the gauge that morning. One of the flashiest rivers in the Ozarks. It can spike 5–10 ft after a storm and drop fast in a dry spell. There's no spring base flow like the Current's.
- Match the gauge to your section. Steelville (USGS 07013000) and Cook Station read the upper river, Sullivan (07018500) the middle, Eureka (07019000) the lower. Conditions differ a lot over 100+ miles.
- Upper for scenery, lower for tubes. Onondaga to Meramec State Park is the prettiest water; below the park is wider and better for big raft and tube groups.
- Book Steelville weekends ahead. The state park and Meramec Caverns stretches fill up. Reserve outfitter shuttles in advance for summer Saturdays.
