Maple Lake Overview
Maple Lake is a small impoundment in Middle Tennessee, roughly 40 miles east of Nashville near the town of Smithville. The lake covers about 150 acres and sits in a rural setting with limited development, making it a quieter alternative to the state's larger reservoirs. It holds largemouth bass, bluegill, and catfish, with seasonal patterns that shift between spring spawning runs and summer heat-driven deeper water.
The lake is managed by the Tennessee Wildlife Resources Agency (TWRA) and is open to public fishing year-round. Access is straightforward — a single public boat ramp and parking area serve most visitors, and the shoreline is accessible from several points. The water is relatively shallow in most areas, averaging 15 to 25 feet, which means structure like fallen trees and vegetation matter more than depth changes.
Maple Lake draws fewer anglers than Cordell Hull Lake or Old Hickory to the west, which can be an advantage if you prefer quieter water. The tradeoff is fewer amenities nearby — no tackle shop on-site, limited food options within a few miles, and no lodging directly at the lake. Most visitors day-trip from Smithville or Nashville.
Key Takeaways
- Maple Lake is a 150-acre impoundment near Smithville, Tennessee, holding largemouth bass, bluegill, and catfish in shallow water averaging 15 to 25 feet deep.
- The public boat ramp is the main access point; shore fishing is possible but limited to a few designated areas along the perimeter.
- Spring (March through May) is the most productive season for bass, when fish move shallow to spawn; summer requires deeper presentations and early morning or evening fishing.
- Tennessee fishing regulations apply: you need a valid fishing license, and bass have a 12-inch minimum length with a 5-fish daily limit.
- No tackle shop, fuel, or food service operates at the lake itself, so bring supplies from Smithville or plan a day trip from Nashville.
When to Fish Maple Lake
Spring (March through May) is the peak season at Maple Lake. Water temperatures climb from the low 50s into the 60s and 70s, triggering largemouth bass to move from deeper winter holes into the shallows to spawn. Bluegill also become aggressive during this window, and catfish feed heavily as water warms. Early morning and late afternoon produce the most consistent action, though overcast days can extend the bite throughout the day.
Summer (June through August) slows the bite considerably. Bass retreat to deeper water and shade during midday heat, making dawn and dusk the only reliable windows. Catfish remain active at night, and bluegill can still be caught in deeper channels. Many anglers shift to night fishing for catfish or focus on early morning topwater presentations for bass.
Fall (September through November) brings a secondary peak as water cools and bass return to shallower feeding zones. October and early November are particularly productive. Winter (December through February) is slowest — bass are deep and lethargic, and most casual anglers stop visiting. Catfish remain catchable year-round but require patience and the right bait.
Access and Boat Ramp Details
The public boat ramp at Maple Lake is located off County Road 141, roughly 3 miles south of Smithville. The ramp is a single-lane concrete launch with a small parking area holding about 15 to 20 vehicles. There is no fee to launch, and the ramp is maintained by TWRA. Water depth at the ramp is adequate year-round for most boats, though during drought years (which occur periodically) the approach can become shallow — call the Smithville ranger station ahead of time if water levels have been low.
The parking area has no restroom facilities, no shade structures, and no fuel dock. Launching and retrieving are straightforward for small to mid-size boats; jet skis and very large pontoons can launch but may require care during low-water periods. The ramp is open dawn to dusk, and overnight parking is not permitted.
Shore fishing is limited. A small area near the boat ramp allows foot access, and a few spots along the eastern shoreline are reachable from County Road 141, but most of the perimeter is private property or inaccessible. If you do not have a boat, ask locally about private land access or plan to fish the ramp area only.
Fish Species and What to Target
Largemouth bass are the primary target. The population is healthy but not large — expect fish in the 1 to 4 pound range most often, with occasional 5 to 7 pounders. Spring spawning runs concentrate fish in 2 to 8 feet of water around vegetation, fallen trees, and the shoreline. Summer requires moving to deeper channels (12 to 20 feet) and fishing early or late. Topwater lures, soft plastics, and crankbaits all produce, depending on season and time of day.
Bluegill are abundant and provide consistent action, especially in spring and early summer. They school in shallow water (2 to 6 feet) around vegetation and structure. Small jigs, crickets, and live minnows work well. Bluegill are not regulated by size or bag limit in Tennessee, so they are a good option for children or anglers wanting a high catch rate.
Catfish (channel and flathead) are present and underutilized by most visitors. They feed year-round, especially at night. Cut bait, chicken liver, and live bluegill all work. Fish the deeper channels and holes after dark for the best results. Catfish have no size or bag limit in Tennessee, making them a good option for a full cooler.
Regulations and Licensing
Tennessee requires a valid fishing license for anyone 13 years old or older. You can purchase a license online through the TWRA website, at most sporting goods stores, or at some convenience stores in Smithville. A one-day license costs less than a week-long option, and a full-year license is available if you plan multiple trips. Children under 13 do not need a license but must follow all other regulations.
Largemouth bass have a 12-inch minimum length limit and a 5-fish daily bag limit. Bluegill and catfish have no size or bag limits. Creel limits and size restrictions can change, so check the current TWRA regulations before you go — the agency publishes an annual fishing guide available online and at license vendors.
Fishing hours are 30 minutes before sunrise to 30 minutes after sunset. Night fishing for catfish is permitted. Live baitfish (minnows and bluegill) are allowed, as are artificial lures and natural baits like worms and crickets. Trotlines and setlines are not permitted without a separate permit.
Nearby Towns and Supplies
Smithville is the closest town, about 3 miles north of the boat ramp. It has a small grocery store, a couple of gas stations, and a few restaurants, but no dedicated tackle shop. If you need fishing gear, your best option is to bring it from Nashville (40 miles west) or order online before your trip. Smithville has a few motels if you want to stay overnight, though most anglers day-trip from Nashville.
Nashville is 40 to 45 minutes away by car and has full services — multiple tackle shops, sporting goods stores, hotels, and restaurants. If you are planning a longer trip or need specialized gear, Nashville is worth the drive. The route from Nashville to Maple Lake is straightforward via I-40 East and US-70 East toward Smithville.
