What Capitol Lake Offers and When to Fish It

Capitol Lake is a 1,000-acre reservoir in downtown Olympia created by the Deschutes River dam. It holds largemouth bass, smallmouth bass, walleye, crappie, and catfish, with seasonal runs of salmon and steelhead. The lake sits within the city limits, making it one of the most accessible saltwater-adjacent fisheries in the Puget Sound region, though it is technically freshwater.

Spring (March through May) brings the strongest fishing. Largemouth bass move into shallow water after spawning, walleye become active in the evening, and spring chinook salmon enter the system. Summer slows the bite as water warms and bass move deeper, though early morning and dusk remain productive. Fall (September through November) sees another strong period as water cools and steelhead begin their run. Winter is slow but possible for walleye and catfish in deeper holes.

Access is straightforward: the lake has public boat launches, shore access at several parks, and a walking path that runs most of the perimeter. Parking is free at the main launch near the Deschutes River dam. No reservation is needed for day use.

Key Takeaways

  • Capitol Lake holds largemouth and smallmouth bass year-round, with spring and fall offering the most consistent action.
  • The lake sits in downtown Olympia with free public boat launches and shore access, making it accessible without a long drive.
  • Washington fishing license and catch record card are required; check current regulations for species-specific rules before you fish.
  • Walleye fishing is best in evening hours, while bass respond to early morning and dusk presentations.
  • Spring chinook and fall steelhead runs add seasonal variety, though timing varies year to year.

Largemouth and Smallmouth Bass Patterns

Largemouth bass dominate the shallow bays and weed edges on the north and west sides of the lake. In spring, fish the 4- to 8-foot zone near submerged timber and cattail edges with soft plastics, crankbaits, or spinnerbaits. Early morning and late afternoon are most productive. By mid-June, bass retreat to deeper structure—look for them around the dam face and in the central basin in 15 to 25 feet of water.

Smallmouth bass are scattered throughout but concentrate on rocky points and the dam structure itself. They respond well to tubes, drop-shot rigs, and small crankbaits. Smallmouth bite consistently through the day better than largemouth, making them a reliable option when the sun is high.

Fall cooling brings both species back to shallower water. September and October are excellent for sight-fishing in clear water and for topwater action at dawn. Throw along the shoreline vegetation and near the boat launch areas where baitfish congregate.

Walleye and Evening Fishing

Walleye in Capitol Lake are most active from one hour before sunset through two hours after dark. Fish live bait (shiners or shad) on a simple slip-sinker rig in 12 to 20 feet of water, or cast small jigs tipped with minnows along the dam face and the deeper central basin. The walleye bite is steady but not explosive—expect to work for each fish.

Spring and fall are best for walleye. Summer heat pushes them deep and makes them sluggish. Winter walleye fishing is possible but requires patience and knowledge of the deepest holes; many anglers skip it in favor of other species.

Bring a headlamp and plan to stay after sunset. The lake is well-lit near the downtown area, but the fishing grounds themselves are dark. A GPS or sounder helps locate the structure where walleye hold.

Salmon and Steelhead Runs

Spring chinook enter Capitol Lake from March through May, though timing varies by year. They move through quickly on their way upstream, so the window is narrow. Fish near the dam face and in the lower lake with spinners, spoons, or small plugs. Most anglers use a boat to cover water efficiently, though shore fishing near the launch is possible.

Fall steelhead arrive September through November. These fish are more aggressive than chinook and will take a wider range of presentations. Drift small spoons or spinners, or cast and retrieve in the deeper sections. Steelhead fishing requires patience—some days produce nothing, while others yield multiple fish.

Check the Washington Department of Fish and Wildlife website for current run forecasts and any special regulations before the season. Salmon and steelhead rules change annually and sometimes mid-season based on run strength.

Regulations and Licensing

You need a valid Washington fishing license and a catch record card (also called a Puget Sound Salmon and Steelhead Catch Record Card if you plan to keep salmon or steelhead). Both are available online through the WDFW website or at sporting goods retailers in Olympia. The license is good for one year from the date of purchase.

Bass, walleye, and crappie have daily catch limits that vary by species. Bass limits are typically 5 per day with a 12-inch minimum size, but check the current regulations—they can change. Walleye limits are usually 5 per day. Salmon and steelhead have separate daily limits and size requirements that depend on the run and the year.

Capitol Lake is open year-round for most species, but salmon and steelhead seasons are defined by WDFW and posted on their website. Barbless hooks are not required on Capitol Lake, but they are encouraged to reduce injury to fish you plan to release.

Access Points and Facilities

The main public boat launch is at the Deschutes River dam, accessible from the Capitol Lake Loop Trail parking area. The launch has a two-lane ramp, parking for about 30 vehicles, and restroom facilities. There is no fee. A second launch exists at the north end of the lake near the Yauger Park area, though it is smaller and less developed.

Shore fishing is possible at several parks around the lake. Priest Point Park on the north shore has a small beach and trail access. The Capitol Lake Loop Trail itself allows walking access to the water at multiple points, making it useful for anglers who want to fish from shore without a boat. The trail is about 3.5 miles and is open year-round.

Facilities are limited. Bring your own water and snacks. The nearest restaurants and shops are in downtown Olympia, a short drive from the lake.

Boat and Tackle Considerations

A small to medium bass boat or jon boat works well on Capitol Lake. The water is calm most days, but afternoon wind can pick up, especially in summer. The lake is only about 75 feet deep at its deepest point, so a standard depth finder is helpful but not essential for bass fishing. For walleye and salmon, a sounder makes a real difference in locating structure and fish.

Bring a net if you plan to land larger bass or salmon. The shoreline is muddy in many spots, making it hard to beach fish safely. A good pair of polarized sunglasses helps sight-fish for bass in spring and fall.

Tackle should include soft plastics (4- to 6-inch worms and crawfish), crankbaits, spinnerbaits, and jigs for bass. For walleye, bring live bait rigs and small jigs. Salmon and steelhead anglers should carry spinners, spoons, and small plugs. All of these are available at local tackle shops in Olympia.

Frequently Asked Questions

Do I need a boat to fish Capitol Lake?

No. The Capitol Lake Loop Trail provides shore access at multiple points, and Priest Point Park has a small beach. Shore fishing is productive for bass and walleye, though a boat lets you cover more water and reach deeper structure where fish hold in summer.

What is the best time of year to fish Capitol Lake?

Spring (March through May) and fall (September through November) are most productive. Water temperatures are moderate, fish are active, and seasonal runs bring variety. Summer is slower due to heat and deeper fish, while winter is possible but requires more effort.

Are there size or catch limits on bass at Capitol Lake?

Yes. Check the current Washington fishing regulations on the WDFW website, as limits can change. Typically, largemouth and smallmouth bass have a 5-fish daily limit with a 12-inch minimum size, but verify before you fish.

Can I keep salmon and steelhead from Capitol Lake?

Yes, during open seasons. You must have a catch record card and follow the daily limit and size rules for that year's run. Seasons and limits are set by WDFW and posted on their website before each season begins.

Is there a launch fee at Capitol Lake?

No. The main boat launch at the Deschutes River dam is free and open to the public. Parking is also free.
