What You'll Find at Tenmile Lake

Tenmile Lake is a 1,200-acre reservoir in Douglas County, about 30 miles south of Roseburg, that holds largemouth bass, black crappie, channel catfish, and bluegill. The lake sits in a mix of coniferous forest and open shoreline, with several developed access points and a marina. Water levels fluctuate seasonally—the lake fills through winter and spring, then drops through summer as irrigation demands increase—which affects where fish hold and how accessible certain areas become.

The lake's primary draw is largemouth bass fishing, particularly in spring and early summer when fish move shallow to spawn. Crappie fishing peaks in late spring through early fall, especially around structure like fallen trees and dock pilings. Catfish are present year-round and respond well to cut bait fished on the bottom at night or early morning. The lake is also popular with families because it has a swimming area, picnic facilities, and a boat ramp that stays open through the main season.

Key Takeaways

  • Tenmile Lake has a developed marina with a boat ramp, fuel, and rentals, making it accessible for anglers without their own boat.
  • Largemouth bass fishing is best from March through June when fish are spawning and feeding in shallow water near the shoreline.
  • Black crappie bite consistently from May through September around submerged trees, docks, and brush piles in 8 to 15 feet of water.
  • Oregon fishing regulations require a valid fishing license for anyone 12 and older, and Tenmile Lake follows statewide bass and crappie bag limits.
  • Water levels drop significantly from July onward, which narrows the usable shoreline and concentrates fish in deeper channels and the main basin.

Seasons and When Fish Bite Best

Spring (March to May) is the most productive season for largemouth bass at Tenmile Lake. Water temperatures climb from the low 50s into the 60s, triggering spawning behavior. Bass move into shallow bays and along the shoreline to build nests, and they feed aggressively before and after spawning. Focus on areas with sandy or gravelly bottom, fallen trees, and emergent vegetation. Early morning and late evening produce the most strikes, though overcast days often bring steady action throughout the day.

Summer (June to August) shifts the bite deeper as water temperatures exceed 70 degrees. Bass retreat to deeper structure—channel ledges, submerged humps, and the edges of drop-offs in 15 to 25 feet of water. Crappie fishing peaks during this period, particularly in early morning and at dusk. Catfish remain active and are often easier to catch than bass in midsummer heat; fish for them after dark with chicken liver, cut shad, or stink bait on the lake bottom. Water levels begin dropping noticeably in July, concentrating fish in the main basin and deeper channels.

Fall (September to November) brings cooler water and renewed bass activity as fish move back toward shallower structure. Crappie fishing remains good through October. By November, water temperatures drop into the 50s and fishing slows considerably. Winter (December to February) sees minimal recreational fishing pressure, though some anglers pursue catfish during mild spells. The lake is open year-round, but access can be limited by weather and water level fluctuations.

Access, Facilities, and Boat Ramps

Tenmile Lake Marina is the primary access point and sits on the north shore near the town of Lakeside. The marina operates a paved boat ramp, fuel dock, and rental fleet (including bass boats and pontoons), making it the easiest entry for anglers without their own vessel. The ramp is typically open from spring through fall, though hours vary seasonally—call ahead to confirm winter availability. Parking is available at the marina, and there is a day-use fee for launching.

A second public access area exists on the south shore, though it is less developed and has limited parking. This spot works well for kayak and canoe anglers or those launching smaller boats. The lake also has several day-use picnic areas and a swimming beach managed by Douglas County Parks, which provide additional parking and facilities but no boat ramp.

Lodging options near Tenmile Lake include the marina's own cabins and RV sites, plus motels and vacation rentals in nearby Lakeside (about 5 miles away). Lakeside also has restaurants, a grocery store, and gas stations. The nearest larger town is Roseburg, about 30 miles north, which has more dining and lodging variety but requires a longer drive to the lake.

Regulations, Licenses, and Bag Limits

Oregon requires a valid fishing license for anyone 12 years old and older. Licenses are available online through the Oregon Department of Fish and Wildlife (ODFW) website, at sporting goods stores, and at the Tenmile Lake Marina. A one-day license costs less than a full-year license and is useful if you are visiting for a short trip. Youth (ages 12–17) and seniors (ages 70+) have reduced-price options.

Tenmile Lake follows statewide bass and crappie regulations. Largemouth bass have a daily bag limit of five fish with a 12-inch minimum length. Black crappie have a daily bag limit of 25 fish with a 7-inch minimum. Channel catfish have no daily limit. These rules apply year-round, though ODFW occasionally issues temporary closures or changes—check the current regulations on the ODFW website or call the Roseburg office before your trip.

Catch-and-release fishing is allowed and encouraged, especially for undersized fish. Use of live baitfish (shiners, shad) is permitted. Artificial lures and flies work well for bass and crappie. Night fishing is allowed, which is useful for catfish anglers.

Tackle and Techniques for Each Species

Largemouth bass respond to a mix of artificial and live bait. Soft plastic worms (4 to 6 inches) rigged Texas-style work well around shallow structure. Crankbaits that mimic shad are effective in spring when bass are feeding actively. Spinnerbaits and buzzbaits produce strikes in low-light conditions. Live shiners (4 to 6 inches) are also productive, particularly in spring. Fish slowly along the shoreline, around fallen trees, and in shallow bays. A 6 to 7-foot medium-action rod with 10 to 15-pound monofilament or braided line is standard.

Black crappie are caught on small jigs (1/16 to 1/8 ounce) tipped with minnows or soft plastics, or on live minnows suspended under a bobber. Vertical jigging over submerged brush piles and around dock pilings is highly effective. A light spinning rod (5 to 6 feet) with 4 to 8-pound line is ideal. Fish slowly and deliberately; crappie often bite gently, so pay close attention to your line.

Channel catfish are best caught on the bottom with cut bait (shad, mackerel, or chicken liver), stink bait, or prepared dough balls. Use a simple three-way rig or slip sinker rig to keep bait on the bottom. Fish after dark or in early morning, and be patient—catfish may take 30 minutes or more to find and eat your bait. A medium-action rod and 15 to 20-pound line are adequate.

Water Levels and Seasonal Changes

Tenmile Lake's water level is managed for irrigation and flood control, which means it rises through winter and spring and drops significantly from July through September. This cycle affects fishing in several ways. In spring, rising water floods shallow areas and creates new habitat for spawning bass and feeding crappie. By midsummer, water levels may drop 10 to 15 feet, exposing previously submerged structure and concentrating fish in the main basin and deeper channels.

Low water levels in late summer can make some shallow bays inaccessible to larger boats, though kayaks and canoes can still reach them. The south shore access point may become unusable if water drops too far. Check current water levels before planning your trip, especially if you are launching a larger boat. The Tenmile Lake Marina can provide up-to-date information on water conditions and which areas are accessible.

Nearby Fishing and Recreation

If you fish Tenmile Lake and want to explore other waters, several options are within an hour's drive. Umpqua Lake, about 15 miles south, is smaller and shallower, with good crappie and bluegill fishing. The North Umpqua River, near Roseburg, offers steelhead and salmon fishing in season. Lemolo Lake, in the Cascade foothills about 45 minutes east, is a larger reservoir with kokanee salmon, rainbow trout, and largemouth bass.

Tenmile Lake itself offers non-fishing recreation as well. The swimming beach is popular in summer, and the surrounding forest has hiking trails and picnic areas. Lakeside has a small downtown with shops and restaurants, making it a reasonable base for a weekend trip that combines fishing with other activities.

Frequently Asked Questions

Do I need a boat to fish Tenmile Lake?

No. The shoreline is accessible from several day-use areas, and kayaks or canoes can reach productive fishing spots. However, a boat gives you access to deeper water and structure that holds more fish, especially in summer. The marina rents boats if you do not have your own.

What is the best time of year to catch largemouth bass at Tenmile Lake?

March through June is peak season. Water temperatures in the 55 to 70-degree range trigger spawning and aggressive feeding. Spring mornings and evenings produce the most consistent action.

Can I fish at night for catfish?

Yes. Night fishing is allowed year-round. Catfish are most active after dark, and many anglers fish from dusk through midnight or set out lines and return in the morning. Bring a headlamp and use caution around the water in low light.

What happens to fishing when water levels drop in summer?

Fish concentrate in deeper channels and the main basin, so you need a boat to reach them effectively. Shallow bays and the south shore access point may become inaccessible. Crappie fishing around docks and submerged structure remains good, and catfish are easier to catch than bass during hot months.

Where do I buy a fishing license?

Online through the Oregon Department of Fish and Wildlife website, at the Tenmile Lake Marina, or at sporting goods stores in Roseburg and Lakeside. A one-day license is the most affordable option for short visits.
