    Lake Details


    What you need to know about fishing Riffe Lake

    Riff Lake is a reservoir formed by the Mossyrock Dam on the Cowlitz River in Washington. The lake is 23.5 miles long with over 11,000 total surface acres and a maximum depth of 360 feet at full pool. The deep cold waters support healthy and diverse trout populations. The Lake is a popular for smallmouth bass but another angler favorite is the land locked coho salmon. Chinook salmon, brown trout, catfish, crappie, and panfish are also present. Coho can be caught closer to the surface using trolling blades and other live bait rigs in the spring but as the summer warms the water and the thermocline builds, the coho will move to much deeper depths and can be caught by trolling deep spoons or crankbaits with leadcore or using slip bobbers and live bait from shore. Bank fishing is available at the fishing bridge on the north end of Riffe Lake.
