So, you’re looking for a map of Little Miami River. Honestly, most people just pull up Google Maps on their phone, see a blue line, and think they’re good to go. Big mistake. If you’ve ever been stuck in a logjam near Milford or realized the "shortcut" you took involves a three-mile trek against a 4-mph current, you know that a standard digital map doesn't tell the whole story.
The Little Miami is Ohio’s first National Wild and Scenic River. It’s 107 miles of shifting sandbars, limestone cliffs, and—depending on the season—some pretty annoying strainers. You need a map that actually understands the topography.
The Problem With Modern Navigation
Most digital maps are flat. They show you where the water is, but they don't show you the low-head dams. They don't show you the private property lines where a grumpy landowner might have words with you if you pull your kayak over for a sandwich. A real map of Little Miami River needs to highlight the access points, specifically the ones managed by the Ohio Department of Natural Resources (ODNR) and various county park districts like Hamilton County or Greene County.
Take the stretch near Clifton Gorge. It’s beautiful. It’s also largely unnavigable by boat because the river narrows into a literal crack in the ground. If you’re looking at a map and think you’re going to kayak from Yellow Springs down to the Ohio River in a single afternoon, you’re in for a very long, very wet surprise.
Breaking Down the River Sections
Let’s talk about the North vs. the South. The upper river, near the headwaters in Clark and Greene Counties, is much narrower. It’s twisty. You’ll find more downed trees here. If you’re using a map to plan a trip, look for the "Little Miami State Park" corridor. This is a 50-mile long "linear" park that follows an old railroad right-of-way.
The trail runs right alongside the water for huge chunks of the trip. This is a massive safety net. If your boat pops or you just get tired of paddling, you can literally hike out to the bike path. You won't find that on most generic river maps.
Further south, once you hit Warren County and move toward Loveland and Milford, the river opens up. It gets wider. It gets deeper. This is where the commercial liveries live. Places like Morgan’s Canoe Livery or Loveland Canoe & Kayak have their own proprietary maps. These are often better than the official state maps because they mark the "trouble spots" that changed during last week’s rainstorm.

Why the USGS Gauges Matter More Than the Lines
A map is a static image of a moving thing. That's a paradox, right? To truly understand a map of Little Miami River, you have to overlay it with real-time data from the USGS stream gauges.
Check the gauge at Kings Mills or Milford.
If the water is under 2 feet, you’re going to be dragging your boat over rocks half the time.
If it’s over 7 feet, you probably shouldn't be out there unless you’re an expert.
The river looks different at every stage. A gravel bar that’s a perfect lunch spot at 3 feet is a dangerous underwater hazard at 6 feet.
You’ve gotta be smart about it. Don't just look at the blue line. Look at the contour lines. The river drops about 5 feet per mile on average, but some sections are much steeper. That’s where you get the "riffles"—not quite whitewater, but enough to flip a canoe if you’re distracted by a Great Blue Heron.
Misconceptions About Public Access
One of the biggest headaches for locals is the "Purple Paint Law." In Ohio, purple paint on trees or fence posts means "No Trespassing." Your map might show a nice flat bank, but if it’s private land, you can’t legally land there unless it’s an emergency.
Stick to the designated access points.
- Constitutional Park
- Oregonia
- Caesar Creek
- Morrow
- Foster’s
- Milford
Each of these has its own quirks. Some have concrete ramps; some are just muddy slides where you’ll probably lose a flip-flop. The ODNR provides a downloadable PDF map that is fairly decent, but it hasn’t been updated in years. The best way to navigate is to cross-reference the official state map with local trail maps from the Little Miami Conservancy.

Wildlife and Landmarks You’ll See
If you’re following your map of Little Miami River correctly, you’ll pass some pretty cool landmarks. Keep an eye out for the remains of old mills. There used to be dozens of them. You’ll see old stone abutments that look like ancient ruins.
And the eagles. Man, the eagles are everywhere now. Ten years ago, seeing a Bald Eagle on the Little Miami was a "call your friends" event. Now? You’ll probably see three or four between Corwin and Morrow. They nest in the massive Sycamore trees that line the banks. Those Sycamores are actually a great navigational tool—their white upper branches stand out against the sky, helping you spot the river corridor from a distance if you’re hiking the nearby hills.
Safety First (The Stuff People Ignore)
Let's get real for a second. The Little Miami is a "Class I" river mostly, but people drown in it every year. Why? Usually, it’s a low-head dam or a strainer.
A strainer is a fallen tree in the current. The water goes through the branches, but you and your boat do not. The pressure can pin you under. On your map, pay close attention to the bends in the river. Trees almost always fall on the "outside" of a bend where the current is fastest and erodes the bank. If your map shows a sharp right turn, stay to the inside.
Also, the dam at South Lebanon. Don't mess with it. There’s a portage for a reason. Maps usually mark these with a little "!" or a red line. Do not think you can "shoot the gap." You can't.
Actionable Steps for Your Next Trip
Stop relying solely on your phone. Batteries die. Screens get wet. Sunlight makes them impossible to read.

First, go to the ODNR website and print the official Little Miami State Scenic River map. It's free. Laminate it or put it in a Ziploc bag.
Second, download the "WaterData" app from the USGS. Mark the Milford and Kings Mills gauges as favorites. Before you even put your car in drive, check the flow rate (measured in CFS—cubic feet per second). For a casual trip, you’re looking for something between 200 and 800 CFS.
Third, check the "Little Miami River Information" groups on social media. These are run by locals who post photos of new logjams. A map from 2022 won't show you the massive oak tree that fell across the channel last Tuesday.
Finally, plan your shuttle. The Little Miami doesn't loop. If you start at Fort Ancient and want to end at Morrow, that’s about a 2-hour paddle, but you need a way to get back to your car. Most people use the bike trail for this. Drop your boat at the launch, drive your car to the takeout, and bike back up to your boat. It’s a workout, but it’s the most efficient way to do it without two cars.
The river is a living thing. It changes every time it rains. Use your map as a guide, not a rulebook. Stay observant, keep your life jacket on, and actually look up from the map once in a while to enjoy the limestone cliffs. They've been there a lot longer than the GPS satellites have.
