Generally, off-channel habitats are small tributaries, frequently spring or ground water-fed, that flow into larger channels. Their diminutive size has caused them to be overlooked in prior inventories and they don't often appear on topographic maps. Although small, these waters can be very productive for salmonids especially coho salmon and trout.  These species actively seek these sites for both spawning and juvenile rearing for the multiple benefits they provide. As small waters with minimal drainage areas, they are usually protected from winter freshet activity that prevents incubating eggs from being scoured out of the gravel or desiccation from siltation leading to high levels of fry production. Additionally, since they are frequently fed by spring or ground water, they usually stay wetted throughout the summer preventing summer stranding losses of parr common in more principal river channels that are surface-fed. The mapped sites are located in the Bogachiel, Callawah, Dickey, Clearwater, Hoh, Quilayute, and Sol Duc basins on the Olympic Peninsula, and all of the Skagit River basin and a portion of the Stillaguamish River basin that are considered "off-channel" habitats for native salmonids.
