The Owyhee River is a tributary of the Snake River located in northern Nevada, southwestern Idaho and southeastern Oregon in the United States. It is 280 miles (450 km) long. The river's drainage basin is 11,049 square miles (28,620 km2) in area, one of the largest subbasins of the Columbia Basin. The mean annual discharge is 995 cubic feet per second (28.2 m3/s), with a maximum of 50,000 cu ft/s (1,400 m3/s) recorded in 1993 and a minimum of 42 cu ft/s (1.2 m3/s) in 1954.
The Feather River is the principal tributary of the Sacramento River, in the Sacramento Valley of Northern California. The river's main stem is about 73 miles (117 km) long. Its length to its most distant headwater tributary is just over 210 miles (340 km). The main stem Feather River begins in Lake Oroville, where its four long tributary forks join—the South Fork, Middle Fork, North Fork, and West Branch Feather Rivers. These and other tributaries drain part of the northern Sierra Nevada, and the extreme southern Cascades, as well as a small portion of the Sacramento Valley. The total drainage basin is about 6,200 square miles (16,000 km2), with approximately 3,604 square miles (9,330 km2) above Lake Oroville.
The San Jacinto River is a 42-mile-long (68 km) river in Riverside County, California. The river's headwaters are in Santa Rosa and San Jacinto Mountains National Monument.

Trampas Canyon is a short tributary of San Juan Creek in southern Orange County the U.S. state of California. It rises in forks on steep slopes of the southern Santa Ana Mountains, and flows north to where it is dammed by Trampas Canyon Dam. Trampas Canyon 1795-006 Dam (33.498359°N 117.587548°W) forms a small lake that branches into four forks running east–west. Exiting the dam, the creek flows north and turns slightly to the west, where it joins San Juan Creek on the left bank, near the confluence of Cañada Gobernadora. Trampas Canyon Creek is ephemeral and only flows during storm events or while Trampas Canyon Dam is releasing, and is not a primary tributary of San Juan Creek.
Temescal Creek is an approximately 29-mile-long (47 km) watercourse in Riverside County, in the U.S. state of California. Flowing primarily in a northwestern direction, it connects Lake Elsinore with the Santa Ana River. It drains the eastern slopes of the Santa Ana Mountains on its left and on its right the western slopes of the Temescal Mountains along its length. With a drainage basin of about 1,000 square miles (2,600 km2), it is the largest tributary of the Santa Ana River, hydrologically connecting the 720-square-mile (1,900 km2) San Jacinto River and Lake Elsinore watersheds to the rest of the Santa Ana watershed. However, flowing through an arid rain shadow zone of the Santa Ana Mountains, and with diversion of ground water for human use, the creek today is ephemeral for most of its length, except for runoff from housing developments and agricultural return flows.
