Fishing season is officially in full swing! With so many lakes, rivers, and marine areas to choose from, it can be hard to pick your next adventure. If you’re never fished Riffe Lake before, or if it’s been a while, you should put it at the top of your list. It’s one of my favorite fishing destinations, and I make it a point to fish it as much as I can every year. Not only is the fishing top notch, but the scenery is beautiful and the surrounding towns are well worth visiting. I can’t think of many other lakes that offer such a wide variety of fish, let alone with such a good opportunity. You can catch brown trout, cutthroat trout, smallmouth bass, chinook salmon, coho salmon, crappie, and brown bullhead. The lake is simply packed with fish, and they’re willing biters. You can take the boat out or shore fish, and finish out the day with a Dam Burger from Pioneer Bar & Grill in Mossyrock before heading home to grill your catch. It’s a bit of a drive, but it’s a great way to spend a day!
Located in Lewis County, Tacoma Power created RIffe Lake by constructing Mossyrock Dam on the Cowlitz River in 1968, flooding the communities of Riffe, Nesika, and Kosmos. It has a maximum depth of 360 feet and is about 23.5 miles long. Not only does the lake boast good populations of land-locked coho salmon, but you can also catch triploid trout! Back in 2020, Tacoma Power bought about 400,000 Rufus Woods strain triploid trout and released them into the lake for anglers to catch. The fish have had plenty of time to grow and they are a ton of fun to catch. If you’re lucky, you may even hook into a steelhead or a chinook salmon on the same day! Tacoma Power releases these fish into the lake as well, once they’ve met their stocking quotas. With such a plethora of fish to catch, you can see why Riffe Lake is a favorite of many northwesterners.
Trolling Techniques
Riffe Lake has plenty of room for boats of all shapes and sizes. It is almost 24 miles long and up to 360 feet deep, which can sound intimidating. Not to worry, there are thousands of fish in the lake, and most days they are willing biters. There have been many days when we can’t even put the planer boards out because the two downrigger poles or lead lines are constantly going off! Early in the season, lead lines, divers, and dropper weights work just fine. The fish are still feeding on the surface and haven’t been driven down to the depths by the hot sun. As the season progresses, however, a good fish finder is a must, particularly for the land-locked coho. Troll until you find a school, mark where you get bites, and don’t be afraid to put a little scent on your lure. I find that the land-locked coho are particularly attracted to pink lures and dodgers. You can use corn or maggots to bait your hooks. Spinners, plugs, spoons- they all catch fish at this lake. I tend to use whatever I already have rigged up for kokanee fishing at other lakes. As for locations, you really can’t go wrong on Riffe Lake- you can start trolling almost as soon as you launch at Mossyrock Park and will usually start catching fish right away. If the fish are being stubborn, try targeting points and coves. Keep an eye on your fish finder if you’re using downriggers, the lake can shallow up surprisingly quickly.
In recent years, it’s been difficult to keep the triploid trout off your hooks if you want to target the land-locked coho salmon in the reservoir. The salmon and trout tend to bite on the same lures and hang out at the same depths in the early season, so you can expect to catch a mixed bag. In general, the coho hang out deeper than the trout in the later season, making downriggers and a good fish finder almost a necessity for targeting them. The salmon tend to like a faster troll, so don’t be afraid to bump it up to 1.9 or 2.2 MPH. However, the trout taste great on the grill and put up a great fight, so most anglers don’t mind catching them.
As a word of caution to boaters, check the water levels at Tacoma Power’s website or give them a call before heading out. The lake’s level fluctuates throughout the year and launching can be difficult when water levels are low. The launch at Mossyrock Park is usually your best bet year-round. It has a large dock with 2 lanes to launch at, which is nice when the ramp is busy. Don’t sweat the crowds too much though, the lake is massive and there is plenty of room for everyone. The other boat launches, Taidnapam and Kosmos, are unsuitable for low water conditions. Check the wind forecast before hitching up the boat- the afternoon winds at Riffe Lake can kick up and create nasty white caps, catching unprepared boaters off guard.
Still Fishing Techniques
Don’t have a boat? No worries, Riffe Lake has plenty of shore access! You can fish at the dam in Mossyrock or at the fishing bridge at Taidnapam Park. These spots can get crowded on nice weekends though. Most shore anglers cast out shrimp or worms under a bobber with a sliding weight. Experiment with setting your bobber stopper anywhere from 3ft to 15 ft until you figure out where the fish are at.
If you can’t get a spot at the dam or fishing bridge, fishing at nearby Lake Mayfield or Swofford Pond is a good alternative. Lake Mayfield is stocked with tiger muskies, which are difficult but extremely rewarding to catch. WDFW also stocks decent numbers of rainbow trout there every year. Swofford Pond has good populations of panfish, stocked rainbow trout, and brown bullhead. There is a boat launch at both lakes, and good shore access. Many folks fish Swofford Pond with inflatables and kayaks, as there is an internal combustion motor ban.
Before you grab those poles and hook up the boat, keep in mind that Riffe Lake has a 5 fish limit. They can be any combination of landlocked salmon and trout, so you cannot legally keep 5 coho and 5 trout. The land locked coho don’t tend to survive catch and release very well, particularly in the summer heat. The lake is large and deep, and those afternoon winds can kick up unexpectedly, so make sure that everyone on your boat has a life jacket. Keep these rules in mind, hook up the boat, and have fun!
