What Tenmile Lake offers and when to fish it

Tenmile Lake sits in the coastal range of southwestern Oregon, about 30 miles inland from Coos Bay. The lake runs roughly 8 miles long and holds warmwater species — largemouth bass, smallmouth bass, crappie, and catfish — in a setting that feels removed from the coast despite being close to it. The water stays relatively clear year-round, and the lake has enough depth and structure to hold fish through summer.

Spring (March through May) and fall (September through November) are the strongest seasons. Bass move shallow in spring to spawn, and crappie bite heavily in both seasons. Summer fishing is possible but slower; the lake warms and fish move deeper, though early morning and evening hours still produce. Winter is coldest and least productive, though some anglers still work the deeper channels.

The lake has two public boat ramps — one at the north end near the town of Lakeside and one at the south end — and both are maintained year-round. Bank access exists at several spots, though much of the shoreline is private. A day-use fee applies at the ramps; check with the Coos County Parks Department for current rates.

Key Takeaways

  • Tenmile Lake holds largemouth and smallmouth bass, crappie, and catfish in clear water that stays fishable through most of the year.
  • Spring and fall are peak seasons; summer requires early morning or evening fishing, and winter is slow but not impossible.
  • Two public boat ramps provide access, one at Lakeside on the north end and one at the south end, both with day-use fees.
  • Structure matters here — fish the rocky points, submerged timber, and weed edges rather than open water.

Bass fishing the points and timber

Largemouth bass in Tenmile Lake respond well to the rocky points that jut into the lake, especially where those points drop off into deeper water. Work a crankbait or jerkbait along the break in 8 to 12 feet of water during spring and fall. In summer, the same points hold bass early and late in the day, but you may need to go deeper — 15 to 20 feet — during midday.

Submerged timber and deadfall are scattered throughout the lake, particularly on the western shore and in the southern basin. A Texas-rigged soft plastic or a jig-and-craw combination works well around these snags. Smallmouth bass often hold tighter to the wood than largemouths do, so don't hesitate to fish close to the cover.

The lake has a healthy population of both species, and the size distribution favors numbers over trophy fish. Expect to catch plenty of 10- to 14-inch fish with occasional 16- to 18-inch fish mixed in. Catch-and-release is common and helps maintain the fishery.

Crappie and catfish in spring and summer

Black crappie spawn in Tenmile Lake in April and May, moving into shallow water (3 to 6 feet) around brush, fallen trees, and the edges of weed beds. A small jig tipped with a minnow or a live minnow under a bobber will produce steady action during this window. The bite slows considerably once water temperatures climb past 70 degrees.

Fall crappie fishing (September through October) mirrors spring — fish return to shallower water as temperatures drop, and the same presentations work. Crappie in Tenmile tend to run 8 to 11 inches, which is solid for the region.

Channel catfish are present year-round but bite most reliably from late spring through early fall. Fish cut bait or chicken liver on the bottom in deeper holes (15 to 25 feet) during the day, or move to shallower flats (6 to 10 feet) at night. The south basin and the deeper channels between the north and south ends hold the most catfish.

Weed beds and shallow-water structure

Tenmile Lake has scattered aquatic vegetation — mostly pondweed and some lily pads — that thickens in summer. These weed beds hold bass, crappie, and panfish and are worth exploring with a weedless presentation. A spinnerbait or a weedless soft plastic works well; you can also flip a jig into the thicker mats.

The weed growth is heaviest on the eastern shore and in the southern third of the lake. In spring, before the weeds fully develop, focus on the edges where vegetation meets open water. By midsummer, the beds can become thick enough to make fishing difficult, so early morning or late evening trips are more productive than midday.

Getting to Tenmile Lake and what to bring

From Coos Bay, take Highway 101 north about 20 miles, then turn east on Highway 42 toward Lakeside. The north boat ramp is right in Lakeside; the south ramp is accessed via County Road 2 from the same highway. Both ramps have parking and basic facilities. The drive from Coos Bay takes roughly 45 minutes to the north ramp and an hour to the south ramp.

Bring a depth finder if you have one — the lake bottom is irregular, and structure that holds fish isn't always obvious from the surface. A map of the lake is useful; the Coos County Parks Department and local tackle shops in Lakeside and Coos Bay have them. Water conditions are generally stable, but wind can pick up in the afternoon, so plan to fish early if you're in a small boat.

The nearest services are in Lakeside (gas, food, lodging) and Coos Bay (full services). No services exist directly at either ramp, so fill up before you arrive.

Tackle and techniques that work year-round

A 6- to 7-foot medium-power spinning rod with 8- to 10-pound monofilament or braided line covers most situations on Tenmile Lake. For bass, crankbaits (1/2 to 3/4 ounce), jerkbaits, and soft plastics (4 to 6 inches) all produce. A 5- to 7-foot medium-light rod works better for crappie and panfish, with 4- to 6-pound line and small jigs or live minnows.

Topwater lures can be effective in early morning and late evening, especially in spring and fall. The lake isn't so large that you need to cover huge distances; focus on working specific structure thoroughly rather than running the entire shoreline.

Local tackle shops in Lakeside and Coos Bay stock standard lures and live bait. Shiners and crawfish are usually available, though calling ahead during off-season is wise. Many anglers bring their own bait to avoid the trip into town.

Seasonal patterns and water temperature

Tenmile Lake warms from roughly 45 degrees in January to a peak of 72 to 75 degrees in August, then cools back down through fall and winter. This temperature swing drives fish behavior more than anything else on the lake. In spring (50 to 60 degrees), bass move shallow to spawn and crappie follow. By early summer (65 to 70 degrees), fish begin moving deeper, and by midsummer (72+ degrees), most species are in 15 to 25 feet of water during the day.

Fall cooling (60 to 50 degrees from September through November) triggers another shallow bite, and this period rivals spring for overall productivity. Winter (below 50 degrees) slows everything down, but fish don't disappear — they concentrate in the deepest holes and respond to slow presentations like jigging or dead-sticking live bait.

A simple thermometer or a depth finder with temperature readout helps you dial in where fish should be. If the surface is 72 degrees in August, fish are likely 18 to 25 feet down; if it's 55 degrees in October, they're moving back to 8 to 12 feet.

Frequently Asked Questions

Do I need a boat to fish Tenmile Lake?

No. Bank access exists at several public spots, though much of the shoreline is private. The north ramp area near Lakeside has some bank fishing opportunity, and the south end has limited access as well. A boat gives you more options and lets you reach deeper structure, but you can catch fish from shore, especially during spring and fall when fish move shallow.

What's the best time of day to fish Tenmile Lake?

Early morning (sunrise to mid-morning) and late evening (two hours before sunset onward) are most productive year-round. In spring and fall, the entire day can be good. Summer midday fishing is slow unless you're fishing deep structure; winter fishing is best during the warmest part of the day, usually midday.

Are there size or catch limits on Tenmile Lake?

Oregon Department of Fish and Wildlife sets the regulations, which change periodically. Generally, bass have a 12-inch minimum with a daily limit, and crappie have a 7-inch minimum. Check the current Oregon fishing regulations before you go, as rules vary by species and can change season to season.

Can I fish Tenmile Lake in winter?

Yes, though the bite is slower. Fish concentrate in the deepest holes (20 to 30 feet) and respond to slow presentations like jigging or live bait fished on the bottom. Winter water temperatures (40 to 50 degrees) slow fish metabolism, so expect fewer bites but the possibility of larger individual fish.

What should I do if the boat ramps are crowded?

Bank fishing at Lakeside or the south end is an alternative, though less productive. You can also try fishing early morning before crowds arrive, or visit on weekdays when pressure is lighter. The lake is large enough that even on busy days, you can find less-crowded areas if you're willing to explore.
