What Radnor Lake Offers Anglers

Radnor Lake is a 684-acre reservoir about 10 miles south of downtown Nashville, managed by the Tennessee Wildlife Resources Agency as a natural area and fishing destination. The lake holds largemouth bass, bluegill, crappie, and catfish in a setting that feels removed from the city despite its proximity. The shoreline is mostly wooded, with limited development, and the water stays relatively clear year-round because the lake is fed by springs and small streams rather than urban runoff.

The lake's depth varies significantly—shallow coves near the inlet reach 8 to 12 feet, while the main basin drops to 60 feet or more. This depth variation means different species use different zones depending on season and time of day. Spring and fall are the most reliable seasons for consistent action, though summer early mornings and winter afternoons can produce well if you know where to look.

Access is limited by design. There is one public boat launch on the north end, and a walking trail circles much of the lake for bank fishing. The lake prohibits gas-powered motors—only electric motors and paddle craft are allowed—which keeps the water quiet and the fish less pressured than on many Tennessee lakes.

Key Takeaways

  • Radnor Lake holds largemouth bass, bluegill, crappie, and catfish in a 684-acre reservoir managed by the Tennessee Wildlife Resources Agency.
  • The single public boat launch is on the north end; electric motors only, no gas engines allowed.
  • Spring and fall produce the most consistent fishing, though early summer mornings and winter afternoons can be productive.
  • A walking trail circles the lake and provides bank fishing access without a boat.
  • A Tennessee fishing license is required; check current regulations for season dates and creel limits before you fish.

How to Reach the Boat Launch and Parking

The boat launch is located at Radnor Lake State Park's main access area on Otter Creek Road, on the north side of the lake. From downtown Nashville, take I-440 south toward Franklin, then exit onto Granny White Pike heading south. Turn right onto Otter Creek Road and follow it to the parking area. The drive takes about 20 minutes from central Nashville.

Parking is available at the launch, though it fills on weekends during spring and fall. There is no fee to launch or fish. The parking area has a restroom and a small picnic area. Arrive early on Saturdays and Sundays if you want a spot close to the ramp.

If you do not have a boat, the walking trail that circles the lake begins at the same parking area. The full loop is about 10 miles, but you can fish shorter sections from any point where the trail approaches the water. The trail is well-maintained and open year-round during daylight hours.

Bass Fishing Patterns by Season

Largemouth bass are the primary target for most anglers at Radnor. In spring (March through May), bass move shallow to spawn in the coves on the north and east sides of the lake. Shallow-running crankbaits, soft plastics in the 4- to 6-inch range, and topwater lures work well in 3 to 8 feet of water. Early morning and late afternoon are most productive.

Summer (June through August) pushes bass deeper and into shade. Fish the main channel drop-offs, submerged timber, and the deeper coves. Early morning before the sun clears the trees is your best window. Deeper-diving crankbaits, jigs, and live shiners fished on the bottom produce better than shallow presentations.

Fall (September through November) brings another shallow bite as water cools and bass move back toward the shallows to feed before winter. This is often the most consistent season. Crankbaits, spinnerbaits, and soft plastics work across a range of depths. Winter (December through February) requires patience; fish the deepest holes and move slowly, using live bait or small jigs.

Bluegill, Crappie, and Catfish Opportunities

Bluegill and other panfish are abundant at Radnor and provide reliable action year-round, especially for anglers without a boat. Fish the shallow areas near the inlet and along the walking trail where the water is 2 to 6 feet deep. Small jigs, live crickets, and worms work well. Spring and early summer are peak seasons, but bluegill bite throughout the year.

Crappie (both black and white) school in deeper water and are most active in spring and fall. Fish the main channel and the deeper coves with small minnows or crappie jigs. Early morning and dusk are most productive. Crappie fishing can be excellent in March and April when they move shallow to spawn.

Catfish are present but less commonly targeted than bass and panfish. They bite best at night and in early morning, especially in summer. Fish the deeper holes with cut bait, chicken liver, or stink bait. The inlet area and the main basin hold the most catfish.

Regulations and Licensing Requirements

A valid Tennessee fishing license is required for anyone 16 and older. You can purchase a license online through the Tennessee Wildlife Resources Agency website, at most sporting goods stores, or at the launch area. Licenses are available as one-day, three-day, or annual options.

Radnor Lake follows standard Tennessee creel limits: largemouth bass have a 5-fish daily limit with a 15-inch minimum length; bluegill and other panfish have a 25-fish daily limit; crappie have a 30-fish daily limit; catfish have no daily limit. Seasons vary by species—check the current Tennessee fishing guide before you go, as dates change year to year.

The lake is catch-and-release only for certain species during specific periods. Confirm current regulations with the Tennessee Wildlife Resources Agency or at the launch area, where posted signs display the rules.

What to Bring and What to Expect

If you are launching a boat, bring a cooler, life jackets for all passengers, and a working kill switch on your electric motor. The lake is small enough that you can cover most productive water in a few hours, so a half-day trip is typical. Bring sunscreen, water, and snacks—there are no concessions at the lake.

For bank fishing from the walking trail, wear sturdy shoes because the trail can be muddy, especially after rain. Bring a headlamp if you plan to fish early morning or dusk. The trail is popular with walkers and runners, so expect to share the space, particularly on weekends.

Radnor Lake is a natural area, not a developed resort. There are no restaurants, bait shops, or fuel docks nearby. The closest services are on Granny White Pike, about 5 minutes away. Plan accordingly and bring what you need before you arrive.

When to Fish and Weather Considerations

Spring (March through May) and fall (September through November) are the most reliable seasons. Water temperatures are moderate, fish are active, and the weather is usually pleasant. Spring offers the bonus of spawning bass in shallow water, which appeals to many anglers. Fall can be even better because fish are feeding aggressively before winter.

Summer mornings are productive if you arrive before sunrise and leave by mid-morning. Afternoon heat pushes fish deep and slows the bite. Winter fishing is possible but requires patience and a willingness to fish slowly in deep water. Midday is often better than early morning in winter because the sun warms the water slightly.

Wind affects fishing more at Radnor than at larger lakes because the lake is relatively small. A light breeze is ideal; strong wind makes boat control difficult with an electric motor and can push fish into deeper water. Check the forecast before you go, especially if you are launching a small boat.

Frequently Asked Questions

Can I fish Radnor Lake without a boat?

Yes. The walking trail circles the lake and provides access to the water at multiple points. Bank fishing for bluegill and panfish is productive, especially in spring and early summer. You will not reach the deepest water or the main channel, but the shallow coves and inlet areas hold plenty of fish.

Are there any restrictions on boat size or type?

Gas-powered motors are not allowed. Only electric motors and paddle craft (kayaks, canoes) are permitted. There is no official size limit, but the lake is small and shallow in places, so large boats are impractical. Most anglers use 16- to 20-foot boats with electric trolling motors.

What is the best time of day to fish Radnor Lake?

Early morning (sunrise to mid-morning) and late afternoon (two hours before sunset) are most productive. Spring and fall offer the longest productive windows. Summer requires an early start to avoid the midday heat. Winter midday can be better than early morning because the sun warms the water.

Do I need to bring my own bait, or can I buy it at the lake?

There are no bait shops at Radnor Lake. Bring your own bait or lures. The closest sporting goods stores are on Granny White Pike, about 5 minutes away, so you can stop on the way if needed.

Is there a fee to launch a boat or fish at Radnor Lake?

No. Launching and fishing are free. You only need a valid Tennessee fishing license, which you can purchase online or at most sporting goods stores.
