Most people driving through Jennings County don't even realize they're passing one of the weirdest, most productive bodies of water in the state. Brush Creek Reservoir Indiana isn't some massive, glitzy resort lake like Monroe or Patoka. It’s smaller. Quiet. It’s got that heavy, silt-bottomed vibe that makes some boaters turn their noses up, but if you’re looking for fish—real, chunky Indiana bass—you’re in the right place. Honestly, if you want a place where you can actually hear the dragonflies and not the roar of a jet ski, this is it.
The reservoir sits tucked away inside the Muscatatuck County Park and Brush Creek Fish & Wildlife Area. It covers about 167 acres, though that number fluctuates a bit depending on how much rain the southern part of the state has been getting. It was originally created as a water supply for the Muscatatuck State Developmental Center. Since that facility closed down, the lake has basically transitioned into a playground for anglers and kayakers who don't mind a little muck on their boots.
What Actually Makes Brush Creek Reservoir Indiana Different?
If you're expecting crystal clear Caribbean blue water, you’re going to be disappointed. Very disappointed. The water here is stained. It’s "tea-colored" on a good day and "chocolate milk" after a heavy storm. But here’s the thing: that turbidity is actually a blessing for the ecosystem. The Indiana Department of Natural Resources (DNR) has managed this area for decades, and they’ve let the natural cover—fallen trees, stump fields, and lily pads—stay put.
This creates a massive amount of structure.
Fish love structure.

Because the visibility is low, the fish aren't as "spooky" as they are in the clear-water quarries nearby. You can get a lure right in front of a largemouth's face without him seeing your boat shadow from ten feet away. It's a shallow lake for the most part, with an average depth that stays under 10 feet, though it drops down toward 20 near the dam.
The Low-Horsepower Rule
One thing that catches people off guard is the motor restriction. You aren't going to see any 200-horsepower bass boats screaming across the surface here. It’s an electric-trolling-motor-only lake. This keeps the water calm and the "peace and quiet" factor high. If you bring a gas motor, keep it tilted up. Better yet, leave the big rig at home and bring a kayak or a jon boat. The ramp is decent, located on the north end, but it’s definitely geared toward smaller watercraft.
Fishing Brush Creek: What You’re Actually Catching
Let’s talk about the biological makeup. The DNR conducts periodic surveys here, and the data consistently shows a healthy population of largemouth bass, bluegill, and crappie. But the real "secret sauce" of Brush Creek Reservoir Indiana is the channel catfish.
Because the bottom is so soft and silty, catfish thrive here.
You’ll find people sitting on the banks near the dam at dusk with stink bait or nightcrawlers, and they rarely leave empty-handed. For the bass hunters, the game is all about weedless setups. If you throw a crankbait with exposed trebles into the middle of the lake, you're going to spend half your day pulling up weeds.
- Topwater Action: Summer mornings are incredible for frogs. Cast right into the lily pads.
- Flipping Jigs: Target the submerged timber along the eastern bank.
- Panfish: Kids love this place because the bluegill are aggressive. A simple bobber and a worm usually do the trick near the shoreline.
There was a rumor a few years back about walleye being stocked, but honestly, don't hold your breath for them. The habitat just doesn't quite suit them like it does the "bucketmouth" bass. The bass here have a slower growth rate than in some southern reservoirs, but they are hardy. You’re looking at a lot of 14-to-16-inch fish, with the occasional 5-pounder lurking under the old pier structures.
The Ghost of Muscatatuck: A Bit of History
It’s hard to talk about Brush Creek Reservoir Indiana without mentioning the old Muscatatuck State Developmental Center. For a long time, this lake was the lifeline for that massive institution. When the center was active, the area was much more "manicured." Now that nature has started taking it back, there’s a slightly eerie, beautiful quality to the surrounding woods.
You might see some old concrete foundations or overgrown paths near the water's edge.
The state took over the management of the land to ensure it didn't just turn into a private housing development. This is why we still have public access today. It’s part of a larger 12,000-acre complex if you count the nearby National Wildlife Refuge, which creates a massive corridor for migratory birds.
Birdwatching and Wildlife
If you aren't into fishing, bring binoculars. Seriously. Because of the proximity to the Muscatatuck National Wildlife Refuge, Brush Creek sees a ton of overflow.

- Great Blue Herons: They stand like statues in the shallows.
- Bald Eagles: They’ve been nesting in the tall pines nearby for years.
- River Otters: They were reintroduced to Indiana in the 90s, and they absolutely love the quiet coves of Brush Creek.
Logistics: Getting There and Staying There
Brush Creek is located about 2 miles north of Butlerville. If you’re coming from Indy, it’s about an hour and twenty-minute drive down I-65 and then cutting across on Highway 50.
Parking and Access:
The parking lot isn't huge. On a holiday weekend, it can get a bit cramped, but since the lake is electric-only, it rarely feels "crowded" once you're on the water. There are no fees to launch, which is a nice change of pace from some of the state parks that charge you just to look at the water.
Where to Stay:
You can't camp right on the shoreline of the reservoir itself, but the Muscatatuck County Park is just down the road. They have primitive sites and some electric hookups. If you want a real bed, North Vernon is your closest bet for hotels. Honestly, most people just make it a day trip.
A Note on Safety
The mud is no joke. I’ve seen people try to wade out to get a better cast and sink up to their knees in that grey, sticky Indiana clay. Stay on the designated paths or in your boat. Also, because it’s a heavily wooded area, the ticks can be brutal in the late spring. Wear the long socks. You’ll thank me later.
The Environmental Reality
Is the water polluted? No. Is it "dirty"? Well, that depends on your definition. It’s a high-nutrient lake. This means it gets algae blooms in the late summer when the heat hits its peak. The DNR monitors the water quality, and while it's safe for swimming (though most people don't because of the weeds), it's primarily a fishing and boating lake.
One thing the experts at the Indiana DNR have noted is the pressure from invasive species. Like many Indiana lakes, they have to keep an eye on Eurasian watermilfoil. This stuff can choke a lake out if it’s not managed. This is why it’s super important to wash your boat and trailer before moving to a different body of water. Don't be that person who brings zebra mussels into a pristine environment.
Why Most People Overlook This Place
Everyone wants the big water. They want the speed. Brush Creek Reservoir Indiana offers the opposite. It offers a chance to see Indiana the way it looked before everything was paved over. It’s dense, green, and a little bit wild.

If you go during the middle of the week, you might be the only person there.
There’s something about the way the mist sits on the water at 6:00 AM that makes the drive worth it. It’s a "working" lake—it doesn't try to be pretty for the cameras. It just provides a solid habitat for fish and a quiet place for people to disappear for a few hours.
Actionable Steps for Your Visit
To get the most out of a trip to Brush Creek, don't just wing it. Southern Indiana weather is fickle, and the lake responds quickly to changes.
- Check the Water Levels: If there has been a massive downpour in the last 48 hours, the reservoir will be muddy and the fishing will be tough. Wait for a three-day dry spell.
- Gear Up: Bring a kayak or a small boat with a 12V or 24V trolling motor. If you’re bank fishing, head toward the dam or the small clearing near the boat ramp.
- Lure Selection: Pack dark colors. Since the water is stained, black/blue jigs or dark purple worms create a better silhouette for the fish to strike.
- Explore the Surroundings: After you're done on the water, drive ten minutes over to the Muscatatuck National Wildlife Refuge. The "Auto Tour" there is a great way to see more deer and migratory birds without having to hike five miles.
- Prepare for No Signal: Cell service is spotty at best once you get down into the hollows near the water. Download your maps ahead of time or just enjoy being "unplugged" for a bit.
Brush Creek Reservoir Indiana isn't for everyone. It’s for the person who values a quiet cast over a loud engine. It’s for the photographer who wants a shot of an eagle without ten other people in the frame. It’s a humble piece of Indiana’s natural history that continues to provide for anyone willing to slow down and look.
