The Colorado River is one of the principal rivers in the Southwestern United States and in northern Mexico. The 1,450-mile-long (2,330 km) river, the 5th longest in the United States, drains an expansive, arid watershed that encompasses parts of seven U.S. states and two Mexican states. The name Colorado derives from the Spanish language for "colored reddish" due to its heavy silt load. Starting in the central Rocky Mountains of Colorado, it flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the Arizona–Nevada border, where it turns south toward the international border. After entering Mexico, the Colorado approaches the mostly dry Colorado River Delta at the tip of the Gulf of California between Baja California and Sonora.
The Merced River, in the central part of the U.S. state of California, is a 145-mile (233 km)-long tributary of the San Joaquin River flowing from the Sierra Nevada into the San Joaquin Valley. It is most well known for its swift and steep course through the southern part of Yosemite National Park, where it is the primary watercourse flowing through Yosemite Valley. The river's character changes dramatically once it reaches the plains of the agricultural San Joaquin Valley, where it becomes a slow-moving meandering stream.
The Salt River is a river in Gila and Maricopa counties in Arizona, United States, that is the largest tributary of the Gila River. The river is about 200 miles (320 km) long. Its drainage basin covers about 13,700 square miles (35,000 km2). The longest of the Salt River's many tributaries is the 195-mile (314 km) Verde River. The Salt's headwaters tributaries, the Black River and East Fork, increase the river's total length to about 300 miles (480 km). The name Salt River comes from the river's course over large salt deposits shortly after the merging of the White and Black Rivers.
The Qu'Appelle River is a river in the Canadian provinces of Saskatchewan and Manitoba that flows 430 kilometres (270 mi) east from Lake Diefenbaker in south-western Saskatchewan to join the Assiniboine River in Manitoba, just south of Lake of the Prairies, near the village of St. Lazare. It is in a region called the Prairie Pothole Region of North America, which extends throughout three Canadian provinces and five U.S. states. It is also within Palliser's Triangle and the Great Plains ecoregion.
Lake Oroville is a reservoir formed by the Oroville Dam impounding the Feather River, located in Butte County, northern California. The lake is situated 5 miles (8 km) northeast of the city of Oroville, within the Lake Oroville State Recreation Area, in the western foothills of the Sierra Nevada. Known as the second-largest reservoir in California, Lake Oroville is treated as a keystone facility within the California State Water Project by storing water, providing flood control, recreation, freshwater releases to assist in controlling the salinity intrusion into the Sacramento-San Joaquin Delta and protecting fish and wildlife.
Alameda Creek is a large perennial stream in the San Francisco Bay Area. The creek runs for 45 miles (72 km) from a lake northeast of Packard Ridge to the eastern shore of San Francisco Bay by way of Niles Canyon and a flood control channel. Along its course, Alameda Creek provides wildlife habitat, water supply, a conduit for flood waters, opportunities for recreation, and a host of aesthetic and environmental values. The creek and three major reservoirs in the watershed are used as water supply by the San Francisco Public Utilities Commission, Alameda County Water District and Zone 7 Water Agency. Within the watershed can be found some of the highest peaks and tallest waterfall in the East Bay, over a dozen regional parks, and notable natural landmarks such as the cascades at Little Yosemite and the wildflower-strewn grasslands and oak savannahs of the Sunol Regional Wilderness.
The Klamath Basin is the region in the U.S. states of Oregon and California drained by the Klamath River. It contains most of Klamath County and parts of Lake and Jackson counties in Oregon, and parts of Del Norte, Humboldt, Modoc, Siskiyou, and Trinity counties in California. The 15,751-square-mile (40,790 km2) drainage basin is 35% in Oregon and 65% in California. In Oregon, the watershed typically lies east of the Cascade Range, while California contains most of the river's segment that passes through the mountains. In the Oregon-far northern California segment of the river, the watershed is semi-desert at lower elevations and dry alpine in the upper elevations. In the western part of the basin, in California, however, the climate is more of temperate rainforest, and the Trinity River watershed consists of a more typical alpine climate.
The humpback chub is a federally protected fish that lived originally in fast waters of the Colorado River system in the United States. This species takes its name from the prominent hump between the head and dorsal fin, which is thought to direct the flow of water over the body and help maintain body position in the swift currents of the Colorado river. The body is almost entirely scaleless, retaining only about 80 mid-lateral scales along the lateral line. The fish is very streamlined, with a thin caudal peduncle and a deeply forked tail. The back is a light olive gray, the sides silver, and the belly white. The dorsal fin usually has nine rays, and the anal fin 10 or more. Maximum recorded length is 38 cm.
The Little River is a tributary of the Red River, with a total length of 217 miles (349 km), 130 miles (210 km) within the Choctaw Indian Reservation in southeastern Oklahoma and 87 miles (140 km) in southwestern Arkansas in the United States. Via the Red, it is part of the watershed of the Mississippi River. Six large reservoirs impound the Little River and its tributaries. The drainage basin of the river totals 4,204 square miles (10,890 km2), 2,204 square miles (5,710 km2) in Oklahoma and 2,036 square miles (5,270 km2) in Arkansas. The Little River and its upper tributaries are popular for recreational canoeing and kayaking.
The Imperial Reservoir is an artificial lake formed by the construction of the Imperial Diversion Dam across the Colorado River in the Lower Colorado River Valley of Imperial County, California, and Yuma County, Arizona. It is 16 miles (26 km) northeast of Yuma, Arizona.
Woods Canyon Lake is a small lake located in northern Arizona, United States, about 30 mi (48 km) east of the city of Payson. It is one in a series of small, canyon-bound lakes located on the Mogollon Rim, collectively referred to as the Rim Lakes. It is among the more developed and accessible of the Rim Lakes. It is also the first reservoir on Chevelon Creek, upstream from Chevelon Canyon Lake.

Rainbow Lake is a 116-acre manmade lake near the town of Pinetop-Lakeside and the community of Lake of the Woods in southern Navajo County, Arizona, United States. The lake was created in 1903 when Mormon settlers dammed Walnut Creek, a tributary of the Little Colorado River, to impound water for irrigation.
Parker Canyon Lake is located in southeastern Arizona, 28 miles (45 km) southwest of Sierra Vista around the Huachuca Mountains and about 5 miles (8.0 km) north of the border with Mexico. The lake is a reservoir formed by a dam in Parker Canyon in the south end of the Canelo Hills in southwestern Cochise County. Parker Canyon is a tributary to the Santa Cruz River in the San Rafael Valley. The facilities are maintained by Coronado National Forest division of the USDA Forest Service.
Catostomus latipinnis is a North American fish identified by its enlarged lower lips. It belongs to the genus Catostomus, commonly known as suckers. Historically, the flannelmouth sucker ranged in the Colorado River Basin, including parts of Wyoming, Utah, Colorado, New Mexico, Nevada, California, and Arizona; however, this species has been entirely extirpated from the Gila River Basin in Arizona.
Moore Dam is a major hydroelectric dam on the Upper Connecticut River between Grafton County, New Hampshire and Caledonia County, Vermont in the northeastern United States. The dam is located near Littleton, New Hampshire, and forms the 3,490-acre (1,410 ha) Moore Reservoir. The Moore Station is the largest conventional hydroelectric plant in New England, in terms of installed capacity and average power generation. The dam and reservoir also provide flood control, recreational boating and fishing.
