The Derby Runs in October and Welcomes Anglers of All Ages
The Lake Sammamish Issaquah Salmon Days Derby is an annual fishing event held on Lake Sammamish, typically in October, that draws families and experienced anglers to fish for coho and chinook salmon. The derby is free to enter and open to anyone with a valid Washington fishing license. You fish from the shore or from a boat, and the event runs for a set period — usually a weekend or a full week — with prizes awarded for the largest fish caught during that time.
The derby is organized by the Issaquah Salmon Days Festival, a community event that celebrates the return of salmon to local streams and the region's fishing heritage. The festival itself is a larger celebration with parades, food, and cultural events, but the derby is the fishing component that brings people to the water. Entry is straightforward: show up during the derby dates with your license, fish the designated waters, and weigh in any fish you want to enter for prizes.

What You Need Before You Fish
A valid Washington fishing license is required to fish in the derby. If you do not have an annual license, Washington offers short-term options — a one-day license or a three-day license — which you can purchase online through the Washington Department of Fish and Wildlife (WDFW) website or at sporting goods retailers throughout the state. The license is inexpensive and takes only a few minutes to obtain.
You will also need appropriate fishing gear for salmon. Most anglers use spinning rods with medium to medium-heavy action, spoons, spinners, or live bait depending on the conditions and their preference. If you are new to salmon fishing, renting gear or borrowing from someone experienced is a good way to start without a large upfront investment. The lake is accessible from several public access points, and parking is typically available near the water.
How the Derby Works and When Fish Are Weighed
During the derby period, you fish Lake Sammamish and keep any salmon you want to enter for prizes. When you catch a fish, you bring it to an official weigh station at a designated time and location — the festival provides these details on their website and at the lake. The fish is weighed, measured, and recorded, and you receive a receipt. Prizes are usually awarded for the largest fish in different categories, such as largest coho, largest chinook, and sometimes youth divisions.
The exact weigh-in schedule and locations vary from year to year, so check the Issaquah Salmon Days Festival website or call ahead to confirm where and when you can weigh fish. Some years weigh-ins happen daily at a central location; other years there may be multiple weigh stations. The festival staff can tell you the current setup and answer questions about how fish are handled and stored before weighing.
Fishing Techniques and Conditions on Lake Sammamish
Lake Sammamish is a large, shallow lake in King County that fills with salmon in the fall as they move toward spawning grounds. Coho salmon typically arrive in September and October, while chinook may be present earlier in the summer and fall. The lake has both shore access and boat launch facilities, so you can fish however you prefer. Shore anglers often have success casting from the public access areas, particularly near the inlet where fish concentrate.
Salmon in the lake respond well to spoons and spinners that mimic baitfish, as well as to live bait such as herring or anchovies if you are fishing from a boat. The water can be cold in October, so dress in layers and bring rain gear — fall weather in the Pacific Northwest is unpredictable. If you are fishing from a boat, make sure your vessel is in good condition and that you follow all boating safety rules. If you are shore fishing, wear a life jacket if you are wading, and stay aware of changing water levels and currents.
Where to Fish and Public Access Points
Lake Sammamish State Park offers the primary public access for the derby. The park has a boat launch, parking, and shore fishing areas. Pine Lake Park, also in the Sammamish area, is another option for shore fishing. Both locations are free or low-cost to access, and both have facilities such as restrooms and picnic areas. The Issaquah Salmon Days Festival website lists the specific access points that are open during the derby and any parking or access fees that may apply.
If you are bringing a boat, launch fees vary by location and year. Call ahead to confirm current fees and any restrictions on boat size or type. If you do not have a boat, shore fishing is productive during the derby, and you do not need special equipment beyond a rod, reel, and tackle. Many anglers fish the same spots year after year and are often willing to share information about where fish are holding.
Prize Categories and What Winners Receive
Prizes are typically awarded for the largest fish in each species category — usually largest coho and largest chinook — and there are often separate youth divisions for younger anglers. The exact prize structure changes each year and may include cash, fishing gear, or gift certificates to local businesses. The festival website publishes the prize list before the derby begins, so you know what you are fishing for.
Even if you do not win a major prize, the derby is a chance to catch salmon, learn from other anglers, and be part of a community event that celebrates the region's fishing culture. Many people fish the derby for the experience rather than the prizes, and the festival atmosphere — with food, music, and family activities happening alongside the fishing — makes it a full day out.
Planning Your Visit and Festival Context
The Lake Sammamish Issaquah Salmon Days Festival is a multi-day event in October that includes the fishing derby, a parade, craft vendors, food booths, and live music. The derby is one part of a larger celebration, so if you are traveling from out of town, you can combine fishing with other festival activities. The festival draws thousands of visitors, so parking and access can be busy on peak days — arriving early in the morning often means better parking and less crowded fishing spots.
Check the Issaquah Salmon Days Festival website for the exact dates of the current year's event, derby rules, weigh-in times, and any changes to access or facilities. The festival is free to attend, though some activities and food vendors charge separately. Bring cash for parking, food, and any gear you might need to purchase on-site.
Frequently Asked Questions
Do I need a fishing license if I am under 16?
Washington requires a fishing license for anglers 16 and older. Children under 16 can fish without a license as long as they are supervised by a licensed adult. The derby welcomes youth anglers, and many years there are prizes specifically for younger participants.
Can I keep the salmon I catch in the derby?
Yes. After your fish is weighed and recorded, you can take it home to cook or process. Many anglers fish the derby specifically to catch salmon for the table. Check current WDFW regulations for any limits on the number of salmon you can keep.
What if the weather is bad during the derby?
The derby typically runs for a full week or weekend, so bad weather on one day does not mean you cannot fish on another. October weather in Washington can include rain and wind, so plan to fish on multiple days if possible. Weigh-in stations remain open throughout the derby period regardless of weather.
Is there a fee to enter the derby?
The derby itself is free to enter. You need only a valid Washington fishing license. Some access points may charge a small parking fee, but the fishing and weigh-in process are free.
Where do I find out the exact dates for this year's derby?
The Issaquah Salmon Days Festival website publishes the derby dates, rules, and weigh-in details each year. You can also call the festival organizers or visit the Lake Sammamish State Park office for current information.
