What You'll Find at Williams Lake

Williams Lake is a shallow desert reservoir about 30 miles south of Spokane that holds walleye, northern pike, largemouth bass, and perch. The lake sits at roughly 2,200 feet elevation in sagebrush country, and it warms quickly in summer — which makes it good for pike and bass but can slow the bite in July and August. The water is moderately clear to murky depending on wind and season, and the bottom is mostly soft mud with some rocky points on the north end.

The lake covers around 1,000 acres when full, but water levels drop through summer as irrigation demands pull from the reservoir. That drawdown concentrates fish in the deeper holes and channels, which can actually improve fishing in late summer if you know where to look. The shoreline is mostly open sagebrush and grassland with a few cottonwoods near the boat launch, so there is little shade and few trees to cast around — this is a sight-fishing and structure-fishing lake, not a timber lake.

Key Takeaways

  • Williams Lake holds walleye, pike, bass, and perch, with walleye and pike being the most consistent targets for visiting anglers.
  • The lake warms and becomes shallow in midsummer, so spring and fall offer better fishing than July and August.
  • Water levels drop through the season as irrigation pulls from the reservoir, concentrating fish in deeper channels and holes.
  • The boat launch is on the west side near the dam, and the lake has no developed shoreline access beyond that point.
  • Walleye bite best at dawn, dusk, and night; pike hunt throughout the day but prefer low-light periods and structure.

When to Fish Williams Lake

Spring (April through May) is the strongest season. Walleye move shallow to spawn in April and early May, and they stay active through the month as water temperatures climb from the 40s into the 50s. Pike are also aggressive in spring, hunting in the shallows and around any hard structure. The water is still cool enough that fish stay active all day, not just at dawn and dusk.

Fall (September through October) is the second-best window. Water temperatures drop back into the 50s and 60s, walleye and pike become active again, and the lake cools enough that you can fish the middle of the day without dead zones. Summer (June through August) can work, but plan to fish early morning, late evening, and night — the midday bite shuts down as the lake warms. Winter is possible but the lake can freeze solid, and access becomes difficult.

Walleye Fishing Tactics

Walleye at Williams Lake respond to live bait and jigs. The most reliable approach is a jig head (1/4 to 3/8 ounce) tipped with a live minnow or leech, worked slowly along the bottom in 8 to 15 feet of water. Cast toward the deeper holes and channels, let the jig settle, and work it with short lifts and pauses. Walleye here are not aggressive strikers — you will feel a tap or a steady weight, not a hard pull.

Trolling live bait rigs (a three-way rig with a sinker and a trailing minnow) along the deeper channels also produces, especially in spring and fall. Fish the north end and the deeper water along the dam. Walleye bite best from one hour before sunset through the first two hours after dark, and again from an hour before sunrise through mid-morning. Night fishing with a headlamp and a jig is often the most productive approach in summer.

Pike and Bass Fishing

Northern pike at Williams Lake hunt in shallow water and around any hard structure — rocky points, old pilings, or the shallow flats on the west side. Throw large swimbaits (4 to 6 inches), spinnerbaits, or crankbaits and work them with a steady retrieve or with pauses and jerks. Pike are less picky than walleye and will chase a lure across open water. Early morning and late evening are best, but pike will bite throughout the day if the water is not too warm.

Largemouth bass are present but less abundant than pike. They hold in the same shallow structure and respond to the same lures — swimbaits and spinnerbaits work better than finesse presentations. The lack of heavy cover (trees, weeds, brush) means bass are more exposed and less predictable than in a timber lake, so you will cover more water and catch fewer fish per cast.

Access and Boat Launch

The only public boat launch is on the west side near the dam. The launch is a concrete ramp with parking for about 20 vehicles and a small gravel lot. There is no fuel dock, no tackle shop, and no services at the lake — bring everything you need from Spokane. The launch fee is modest (check with the local ranger district or county for current rates), and the ramp is usually open year-round unless ice or maintenance closes it.

There is no developed shoreline access beyond the launch area. The entire shoreline is either private land or sagebrush country with no trails or parking. If you do not have a boat, you are limited to fishing from the launch area itself, which is not productive. A small boat (14 to 18 feet) is ideal — the lake is shallow and the wind can pick up in afternoon, so a heavy bass boat is overkill and a canoe is risky.

Gear and Tackle for Williams Lake

Bring a medium-power spinning rod (6 to 6.5 feet) for walleye and perch, and a medium-heavy rod for pike. Spool with 6 to 8-pound monofilament or braided line for walleye, and 10 to 15-pound for pike. A small tackle box with jig heads (1/4 to 3/8 ounce), live minnows or leeches, swimbaits (4 to 6 inches), spinnerbaits, and a few crankbaits covers most situations.

Bring sunscreen, a hat, and water — the lake is exposed and the sun reflects hard off the water. A depth finder is useful but not essential; the lake is small enough that you can learn the structure in a few trips. A net is helpful for pike, which can thrash and throw hooks. If you plan to fish at night, bring a good headlamp and extra batteries.

Regulations and Licensing

Washington State requires a fishing license for anyone 16 and older. You can purchase a one-day, three-day, or annual license online through the Washington Department of Fish and Wildlife website or at sporting goods stores in Spokane. Check the current regulations for Williams Lake — walleye, pike, and bass have different season dates and bag limits that change year to year. Perch usually have a generous limit and no closed season.

The lake is managed by the local irrigation district or county, so there may be additional local rules about hours, motor restrictions, or seasonal closures. Call ahead or check the access point for posted regulations. Most years the lake is open year-round, but water level and ice can make access difficult in winter.

Frequently Asked Questions

Is Williams Lake good for beginners?

Yes, if you have a boat. The lake is small, the fish are straightforward (walleye and pike respond to simple jig-and-minnow presentations), and there are no complicated weed beds or timber to navigate. Without a boat, access is very limited.

What is the best time of day to fish?

Dawn and dusk are most reliable for walleye and pike. In summer, fish early morning (before 9 a.m.) and late evening (after 7 p.m.). In spring and fall, the bite is more consistent throughout the day.

Can I catch perch at Williams Lake?

Yes. Perch are abundant but small (mostly 6 to 9 inches). Fish for them with small jigs and live minnows in 10 to 20 feet of water. They are good for a fun afternoon if the walleye and pike are slow.

How far is Williams Lake from Spokane?

About 30 miles south. From downtown Spokane, take I-90 south toward the Tri-Cities, then exit onto local roads toward the lake. The drive is roughly 45 minutes to an hour depending on traffic and which part of Spokane you start from.

What should I do if water levels are very low?

Low water concentrates fish in the deeper channels and holes, which can actually improve fishing. Focus on the deepest areas near the dam and the north end. The launch may become difficult if the ramp is exposed, so check conditions before you go.
