Lake Merwin, Washington – World Atlas
Lake Merwin is a reservoir formed by the construction of Merwin Dam on the Lewis River at the boundary between the Clark and Cowlitz Counties in the US State of Washington. The lake has 51 km of shoreline, numerous inlets, and a peaceful and tranquil upper arm. The upper arm is actually a section of the original Lewis River, which used to flow freely through the valley before the construction of the Merwin Dam. The waters of Lake Merwin are renowned for being extraordinarily deep, and the Kokanee fishing here is among the greatest in the Pacific Northwest. Being an oligotrophic lake, the waters of Lake Merwin have a high concentration of dissolved oxygen and few accumulated nutrients.

Brief History Of Lake Merwin
The bottom of Lake Merwin used to be rich farmland with pear orchards and old-growth forests. Generations of people have lived in and grown their families in the valley since it was first inhabited in 1870. Families listed their farms for sale as the cities expanded, and the Northwestern Electric Company gradually acquired them. In 1931, the construction of the Merwin Dam was completed leading to the creation of the Merwin Lake. After the valley’s old-growth trees were felled and the dam’s gates were closed in 1950, the river started to rise. Homes were flooded first, and then the blooming locust trees vanished. The locust trees are claimed to stand still at the lake’s bottom today.

One of the most fantastic spots in Southwest Washington for catching kokanee is Lake Merwin, which is also the only location close to Portland and Vancouver where you can capture a huge tiger muskie. In 1995, tiger muskies were planted to aid squaw fish population management. Kokanee, bull trout, coho, chinook, northern pike, and minnow are among the fish species found in the lake. Early spring is the ideal time to go fishing in Lake Merwin.

Lake Merwin is a stunning and tranquil reservoir where boaters can observe both the sunrise and sunset.
