Both Whites and Thomas creeks originate from the east side of the Carson Range at approximately 9,000 feet. At 6,000 feet, they depart from the Carson Range, flow onto the upper slopes of the Truckee Meadows, and ultimately empty into Steamboat Creek. On their way down the mountain, each creek runs through a matrix of U.S. Forest Service land and private property. By the time the creeks reach US 395, they are fairly channelized and provide poor habitat for trout. Current sport fish include brook and rainbow trout. Brook trout tend to be found in the higher elevations, while rainbow do better in the lower reaches. The tout population in the upper section of Whites Creek (above Timberline Drive) is fairly low, which is probably due to the high gradient and scarcity of pools. Thomas Creek exhibits abundant populations of both rainbow and brook trout. Dry fly fishing and anglers bait fishing with worms, salmon eggs, or Power Bait are popular angling methods. Primitive camping is allowed on public land.
