The Salmon River is a tributary of the Queets River in U.S. state of Washington.
The river flows roughly from east to south, with the North Fork Salmon River, Middle Fork Salmon River, South Fork Salmon River, combining to form the Salmon River, which empties into the Queets River. The river's length, including its longest source tributary, the Middle Fork, is 18miles. The main stem Salmon River, below the North Fork, is about 13miles long.[1] The Salmon's drainage basin is 56sqmi in area.[2]
The North, Middle, and South Fork watersheds are composed of shale, and sandstone, both sedimentary rocks, while the watershed of the lower Salmon River is composed of "coastal piedmont consisting of porous, unconsolidated deposits of Olympic alpine glaciers, including gravels, sands, silts and clays."[3]
More than 80% of the watershed is covered by coniferous forests (including Sitka spruce, western hemlock, and Douglas-fir), with the remainder being hardwood stands and unforested wetlands.[3]
There is a hatchery on the river that breeds Coho salmon and Chinook salmon. Some number of hatchery Winter steelhead smolts are planted in the river every year.[4] Sea-run cutthroat trout[5] and Chinook salmon also inhabit the river.
