As a lifelong angler and outdoor writer, I’ve spent countless hours on the water, and few experiences rival the thrill of hooking into a truly massive fish. In Washington State, that often means targeting walleye, and specifically, the pursuit of a 20 pound fish. While not common, these behemoths do exist, and the Columbia River and its reservoirs, particularly Lake Wallula, are known hotspots. This guide will delve into everything you need to know about catching a trophy walleye, from understanding the fishery to the techniques and resources that will maximize your chances of landing a 20 lb fish. We’ll also touch on the current Washington State record walleye and how it stacks up against the US record walleye.
Walleye (Sander vitreus) are a popular game fish in Washington, originally introduced from the Midwest. They’ve thrived in the Columbia River system, offering anglers consistent action and the potential for truly impressive catches. The Columbia River and Lake Wallula, formed by the McNary Dam, provide ideal habitat – deep, slow-moving water with plenty of structure. Understanding their behavior is key. Walleye are primarily bottom feeders, preferring to ambush prey in low-light conditions. This makes them particularly active during dawn and dusk, and even at night. They are also highly sensitive to water temperature and clarity, influencing their location and feeding habits. You can find more information on walleye biology and habitat from the Washington Department of Fish and Wildlife (WDFW).
Lake Wallula consistently produces some of the largest walleye in Washington State. Its unique structure, created by the dam, provides excellent holding areas for these fish. The lake’s depth, combined with submerged islands and channels, creates a complex ecosystem that supports a healthy walleye population. Many anglers specifically target the areas near the McNary Dam and the confluence of the Snake and Columbia Rivers. The Columbia River Walleye Anglers Association (CRWAA) is a fantastic resource for up-to-date fishing reports, tournament information, and conservation efforts related to walleye in the region.
Knowing how to estimate a fish’s weight based on its length is helpful, especially when practicing catch and release. While there’s variation, a general rule of thumb is that a 28-30 inch walleye will typically weigh around 10-12 pounds. To reach a 20 pound fish, you’re looking at lengths exceeding 32-34 inches – truly exceptional specimens. Remember that girth also plays a significant role in weight. A thicker walleye will weigh more than a slender one of the same length. REI’s Expert Advice section offers a helpful guide to fish weight estimation.
Landing a 20 lb fish requires the right gear and a strategic approach. Here’s a breakdown of what I recommend:
Several techniques are particularly effective for targeting large walleye:
Don't be afraid to experiment with different colors and presentations until you find what the fish are responding to on a given day. Pay attention to water clarity and depth, and adjust your tactics accordingly.
The current Washington State record walleye, as of October 26, 2023, is a massive 25.15-pound fish caught from Lake Roosevelt in 1991. This fish measured 36.1 inches in length. While Lake Wallula has produced many large walleye, it hasn’t yet yielded a record-breaker. The US record walleye, recognized by the International Game Fish Association (IGFA), is a 25 pounds 14 ounces fish caught from Fort Peck Reservoir, Montana, in 1960. These records demonstrate the incredible potential size that walleye can reach.
| Record | Weight | Location | Date |
|---|---|---|---|
| Washington State | 25.15 lbs | Lake Roosevelt | 1991 |
| US (IGFA) | 25 lbs 14 oz | Fort Peck Reservoir, MT | 1960 |
As anglers, we have a responsibility to protect the resource for future generations. Practicing responsible angling is crucial. This includes:
The USDA Forest Service (fs.usda.gov) also provides valuable information on responsible recreation in national forests, which often border prime walleye fishing areas.
If you’re planning a trip to Lake Wallula specifically to target trophy walleye, here are a few tips:
Landing a 20 pound fish is a challenging but rewarding goal. With the right knowledge, gear, and a little bit of luck, you can increase your chances of experiencing the thrill of catching a true giant.
