What You'll Find at South Tenmile Lake

South Tenmile Lake is a shallow, weedy reservoir in Douglas County that holds largemouth bass, bluegill, and crappie. The lake sits about 30 miles southeast of Roseburg and covers roughly 180 acres when full. It's a warmwater fishery, meaning the water stays relatively warm through summer and supports species that thrive in those conditions rather than cold-water trout.

The lake's shallow depth and heavy aquatic vegetation make it ideal for bass fishing, especially if you're comfortable working around weeds and lily pads. Bluegill and crappie are abundant and willing, making this a solid choice if you want consistent action without a long drive from the Willamette Valley. The setting is quiet and undeveloped — you won't find resorts or marinas here, which means fewer people but also fewer services.

Key Takeaways

  • South Tenmile Lake holds largemouth bass, bluegill, and crappie in shallow, weedy water that rewards anglers who know how to fish vegetation.
  • Access is by boat launch only; there is no bank fishing, and the nearest services are in Roseburg, 30 miles away.
  • Oregon's warmwater fishing season runs year-round, but spring and early summer produce the most consistent catches.
  • You need an Oregon fishing license and must follow state regulations on bag limits and tackle, which differ between species.
  • The lake can drop significantly in late summer and fall as water is drawn down for irrigation, which affects both access and fish location.

Access and Boat Launch Details

The only public access to South Tenmile Lake is via the South Tenmile Lake Recreation Area boat launch on the north shore. The launch is a single-lane concrete ramp suitable for trailers, and parking is available for vehicles with trailers. There is no day-use fee, but the lot can fill on weekends during peak season.

The road to the launch is paved but narrow in places. From Roseburg, take Highway 138 east toward Diamond Lake, then follow signs for South Tenmile Lake Recreation Area. The drive takes roughly 45 minutes from Roseburg. There are no services at the lake itself — no fuel, food, or restrooms — so plan accordingly and bring what you need from town.

Bank fishing is not an option here. The shoreline is mostly private property or inaccessible, so you must have a boat. Even a small aluminum boat or canoe works well for this lake, and the shallow water means you don't need a large engine.

What Species to Target and When

Largemouth bass are the primary draw. They spawn in spring (April through June) when they move into shallow water near vegetation, making that the most productive season for sight-fishing and topwater lures. Summer fishing can be good early and late in the day, but midday heat pushes bass deeper into weeds. Fall and winter are slower, though bass remain present year-round.

Bluegill and crappie are abundant and bite consistently throughout the open season. Bluegill peak in late spring and early summer, and they're eager on small jigs, flies, and live crickets. Crappie fishing is often best in spring and again in fall, and they respond well to small minnows and crappie jigs around structure and vegetation.

The lake's shallow depth means water temperature swings widely with the seasons. In summer, the entire lake can warm to 75 degrees or higher, which concentrates fish in the deepest holes and thickest weed beds. In winter, the lake rarely freezes solid, but fishing slows considerably.

Tackle and Techniques That Work

For bass, bring weedless soft plastics, spinnerbaits, and topwater lures. The heavy vegetation demands weedless presentations — a Texas-rigged worm or a weedless jig will save you from constant snags. Topwater plugs and poppers work well in spring and early morning. Cast tight to lily pads and fallen timber, and be ready for aggressive strikes.

For bluegill and crappie, light spinning tackle with 4- to 6-pound line is ideal. Small jigs (1/32 to 1/16 ounce) in white, chartreuse, or black work year-round. Live crickets and small minnows are effective if you prefer live bait. A slow retrieve or vertical jigging near vegetation produces steady catches.

Bring polarized sunglasses — the shallow water and clear conditions often allow you to sight-fish, especially for bass in spring. A net is useful for landing bluegill and crappie, and a depth finder helps you locate the deeper holes and weed edges where fish congregate in summer.

Oregon Fishing License and Regulations

You must have a valid Oregon fishing license to fish South Tenmile Lake. Licenses are sold online through the Oregon Department of Fish and Wildlife website, at sporting goods stores, and at some convenience stores. A one-day license costs less than a full-year license if you're visiting just once.

Bag limits for warmwater species in this lake are set by the state and can change year to year. As of recent regulations, largemouth bass have a daily limit of five fish with a 12-inch minimum length. Bluegill and crappie typically have higher limits (often 25 fish per day combined), but always check the current Oregon Sport Fishing Regulations before you fish — regulations are posted on the ODFW website and in the printed guide available where licenses are sold.

Tackle restrictions are minimal for warmwater fishing. Artificial lures and live bait are both legal. There are no special restrictions on hook size or line type for this lake.

Seasonal Water Levels and What They Mean

South Tenmile Lake is a reservoir used for irrigation storage, which means water levels fluctuate significantly. In spring and early summer, the lake is usually full or near full. By late summer and fall, as water is drawn down for agricultural use, the lake can drop 10 to 15 feet or more. This drawdown affects both access and fishing.

When the lake is low, the boat launch may become difficult to use, and some shallow areas that hold fish in spring become inaccessible. Fish concentrate in the remaining deeper water, which can actually improve fishing if you know where the holes are. Check current water levels before you go — the U.S. Bureau of Reclamation publishes reservoir levels online, and local tackle shops in Roseburg can tell you whether the launch is usable.

Winter rains typically refill the lake by late fall or early winter, so the cycle repeats. Plan your trip accordingly: spring and early summer offer full water and active fish; late summer and fall offer lower water and concentrated fish but potential access issues.

Nearby Lodging and Services

Roseburg is the nearest town with lodging, restaurants, and tackle shops. It's 30 miles away, so plan on a 45-minute drive each way. Several motels and a few larger hotels operate in Roseburg, and you'll find grocery stores and gas stations there as well.

If you want to stay closer, the Diamond Lake area (about 20 miles further east) has resort lodging and campgrounds, though those are oriented toward trout fishing on Diamond Lake itself. South Tenmile Lake has no campground or overnight facilities on its shores.

Tackle and bait shops in Roseburg can provide current information on water levels, recent catches, and any changes to access or regulations. Calling ahead is worth the effort, especially if you're planning a trip during shoulder seasons when conditions change quickly.

Frequently Asked Questions

Can I fish South Tenmile Lake year-round?

Yes, Oregon's warmwater fishing season is open year-round for largemouth bass, bluegill, and crappie. However, winter fishing is slow, and water levels drop significantly in late summer and fall, which can affect access and fish location. Spring and early summer are the most productive times.

What's the best time of year to fish here?

April through June is ideal for bass, when they spawn in shallow water and are aggressive. Bluegill and crappie are also active during this period. July and August can be good early and late in the day, but midday heat pushes fish into thick cover. Fall fishing is slower but still possible.

Do I need a boat to fish South Tenmile Lake?

Yes, bank fishing is not available. The only public access is the boat launch on the north shore. A small aluminum boat, canoe, or kayak works fine — you don't need a large or powerful boat for this shallow lake.

What happens if the water level is too low to launch?

If the launch becomes unusable due to low water, you cannot fish the lake without private access. Check current water levels through the U.S. Bureau of Reclamation website or call a Roseburg tackle shop before driving out. Late summer and fall are the highest-risk times for access problems.

Are there any special regulations for this lake?

South Tenmile Lake follows standard Oregon warmwater regulations. Bag limits and minimum sizes vary by species and can change annually. Check the current Oregon Sport Fishing Regulations guide (available online or where licenses are sold) before your trip to confirm limits for bass, bluegill, and crappie.
