Cottonwood Creek is a tributary of Rock Creek that enters about five kilometers below the outlet of Rock Lake. A total of 55 locations along Cottonwood Creek and its two main tributaries, Kamiache and Pleasant Valley Creeks, were electrofished to determine relative abundance of each species present. Eight species were collected throughout the drainage. Native minnows dominated the fish fauna, comprising 52% of all species collected. Two nonindigenous species, the brook stickleback, Culaea inconstans and fathead minnow, Pimephales promelas, were recorded for the first time in the Cottonwood Creek drainage. Rainbow trout, Oncorhynchus mykiss were also collected from this drainage. Rainbow trout in Cottonwood Creek could have come from 1) hatchery plants into Rock Lake (Washington Department of Fish and Wildlife has stocked the lake with rainbow trout from the Spokane and Lyons Ferry hatcheries); 2) wild (naturally reproducing) fish derived from these hatchery stocks, or 3) an indigenous population of wild (naturally reproducing) interior redband trout. The fish appeared to be wild (naturally reproducing) because they did not bear characteristic markings of a hatchery fish, such as stubby fins. Rainbow trout collected during sampling efforts were analyzed using microsatellite DNA analysis for stock identification. Nei's genetic distance was used to measure the relationship between Cottonwood Creek rainbow trout and six other eastern Washington trout populations: two populations derived from plants of coastal rainbow trout, a population of cutthroat trout and three redband rainbow trout populations. Cottonwood Creek rainbow trout most closely resembled those from Buck Creek in the Spokane River drainage. The Buck Creek rainbow population is a coastal variety that was planted into Buck Creek from the Spokane Fish hatchery and subsequently began to naturally reproduce in the wild. Thus, it is probable that the Cottonwood Creek rainbow trout were derived from Spokane hatchery plants into Rock Lake that subsequently began to reproduce in the wild"--Document.
