Historically, Rio Grande Cutthroat Trout occupied all cool waters in the Rio Grande drainage, including the Chama, Jemez and Rio San Jose drainages, along with suitable waters of the Pecos and Canadian drainages. They currently live in only about 100 headwater streams, occupying 10 percent of their former range. They have a yellowish green-gray to gray body with scattered black spots, and a densely spotted tail. Adults grow up to 12-13 inches long. The Rio Grande Cutthroat has officially been designated as the New Mexico State Fish.

The historic range of California golden trout (CGT) includes two watersheds draining the Kern Plateau of the southern Sierra Nevada Mountain Range in California. CGT are native to Golden Trout Creek (GTC) and the South Fork of the Kern River (SFKR), an area encompassing approximately 593 square miles (1,536 sq. km). They historically occupied GTC from the headwaters, with the possible exception of the upper reaches of some tributary streams and headwater lakes, downstream to a series of waterfalls near the mouth. In the SFKR, CGT were present from the headwaters downstream at least to the southern end of the present-day Dome Land Wilderness (Figure 1) and perhaps downstream of Lake Isabella. They may also be found...

The distribution of Coastal Cutthroat Trout (CCT) is broader than that of any other cutthroat trout sub-species. It extends along the Pacific coast of North America from the Eel River in northern California, to the Prince William Sound area of Alaska, extending to Gore Point on the Kenai Peninsula. The eastern range of the subspecies rarely extends farther inland than 160 km and usually is less than 100 km. The eastern range is generally bounded by the Cascade Mountain Range in California, Oregon, and Washington, and by the Coast Range in British Columbia and southeastern Alaska. In the Columbia Drainage CCT extend eastward to river km 309, almost to he mouth of the Deschutes River. This range coincides closely...

Greenbacks are native to the Arkansas and South Platte River basins in Colorado's Front Range mountains, and a few South Platte tributaries in extreme southeastern Wyoming. It was listed as endangered in 1973 but downlisted to threatened when a recovery plan began in 1978. The Greenback Cutthroat Trout's maximum size is 18 inches, and it has the largest spots of all cutthroats. Despite its name, the Greenback Cutthroat's back is not particularly green.

Arctic char have been documented in lakes and outlet streams in the Brooks Range, the Kigluaik Mountains, the Kuskokwim Mountains, the Alaska Peninsula, Kenai Peninsula, Kodiak Island, and in a small area of Interior Alaska near Denali National Park and Preserve. However, a comprehensive survey of Alaska water bodies that contain Arctic char is lacking. The vast majority of lakes and rivers where they have been surveyed and found are within Federal lands such as the National Petroleum Reserve-Alaska, Arctic National Wildlife Refuge, Gates of the Arctic National Park, Noatak National Preserve, Togiak National Wildlife Refuge, and others. Most populations of Arctic char are well off the road system. Throughout most...

The Lahontan Cutthroat Trout is the largest cutthroat trout species, and is the state fish of Nevada. The present distribution is restricted to a few lakes and streams within and outside the historic range. Dark olive backs and reddish to yellowish sides frequently characterize the Lahontans found in streams, while the sides of lake-dwelling Lahontans are often silvery. The largest recorded Lahontan trout weighed in at 41 pounds.

The Paiute Cutthroat Trout is native only to Silver King Creek, a tributary of the Carson River in the Sierra Nevada Mountains in California. It is believed that the Paiute evolved from a sub-population of Lahontan Cutthroat Trout that became isolated in the creek. Pauites have a purple coloration, and they are distinguished from other cutthroat species because they lack most body spots. They grow to a maximum size of 10 inches and weigh up to 1 pound. The Paiute Cutthroat Trout is a federally listed threatened species. The only populations of Paiute Cutthroat Trout in the Silver King Creek basin now exist upstream of their native range, isolated from non-native trout by barrier waterfalls. Chemical treatments using...

Dolly Varden are the most widely-distributed salmonid in Alaska and occupy most coastal waters in the state. Two forms or sub-species of Dolly Varden have been described in Alaska. The northern (S. m. malma) form is distributed from the Mackenzie River to the north side of the Alaska Peninsula while the southern form (S. m. lordi) is distributed on the south side of the Alaska Peninsula to the southern tip of Southeast Alaska, including Kodiak and the Aleutian Islands. The distribution of each form has changed in recent years with knowledge gained from genetic analysis. Both forms have anadromous and stream-resident forms but the lacustrine (lake dwelling) form is rare in the northern form but common in the southern...

The Bonneville Cutthroat Trout was historically found in the Bonneville Basin, including suitable habitat within the basin portions of Utah, Idaho, Wyoming and Nevada. Although scientists believed that pure strains of Bonneville Cutthroat were extinct 30 years ago, small populations have been found in nearly 70,000 acres of lakes and 850 miles of streams. The Bonneville Cutthroat's coloration is less vivid than other cutthroat species, and it has large, evenly distributed spots.

Alaskan Lake Trout range widely in Alaska from north to south but are not found in the Yukon-Kuskokwim lowlands or the coastal drainages of Southeast Alaska. Lake trout inhabit the deeper lowland lakes along the central Arctic coastal plain, as well as waters in the Brooks Range and Alaska Range. Lake trout inhabit clear, mountain lakes in northern Alaska as well as turbid glacial lakes on the north side of the Chugach Range and on the Kenai Peninsula.

The historical range of the Yellowstone Cutthroat Trout was upstream of Shoshone Falls on the Snake River and tributaries. It also existed across the Continental Divide in Yellowstone Lake and in the Yellowstone River, and its tributaries downstream to the Tongue. Yellowstone Cutthroat can be distinguished from other cutthroat trout by their larger black spots, clustered toward the tail, and by their gray, gold, and copper hues. The Yellowstone Cutthroat measures from 6 to 20 inches long when it reaches maturity.

The Gila trout is one of the rarest trout species in the United States. Historically, the fish was native to the San Francisco, Verde, Gila, and Agua Fria River drainages in New Mexico and Arizona. By the 1950s, however, its range was reduced to only four streams in the Gila River headwaters in New Mexico, and none were found in Arizona. The Gila trout was listed as federally endangered in 1967, and re-classified as threatened in 2006 after efforts to restore populations were successful. The Gila trout can grow to about 17-18 inches and is yellowish-brown, gold or copper.

Redband Trout are subspecies of the rainbow trout, and exist in two well-defined geographic regions. The Columbia River Redband Trout is found in Montana, Washington and Idaho, and the Great Basin Redband Trout is found in southeastern Oregon and parts of California and Nevada. The Redband Trout is similar in appearance to the rainbow trout, but has larger, more rounded spots and parr marks that remain into adulthood. They generally grow larger than 10 inches.

Officially designated as Montana's state fish, the Westslope Cutthroat's historical range included all of Montana west of the Continental Divide, as well as the upper Missouri River drainage. The average size of these fish is 6 to 16 inches, depending on habitat. It is often difficult to distinguish the westslope from other cutthroat species, but it tends to have more small spots by the tail and none by the pectoral fin. Also, the Westslope Cutthroat Trout is more of a silvery or greenish color than other cutthroats.

Native populations of Alaskan coastal rainbow trout occur in freshwater systems throughout much of the southern coastal zones of Alaska. Their historic distribution in Alaska is from the southern tip of the southeast panhandle north to the southern tributaries of the Kuskokwim River drainage. Their distribution includes the Alaska Peninsula, Kenai Peninsula, Kodiak Island, and the Copper River. They can also be found in the Naknek, Kvichak, Illiamna, Nushagak, Alagnak, Susitna, and Togiak river systems.

The Colorado River Cutthroat historically occupied most cool water habitats of the Colorado River watersheds in Colorado, southern Wyoming, eastern Utah, extreme northwestern New Mexico and northeastern Arizona. Currently, however, Colorado River Cutthroat trout occupy approximately 16 percent of its historic range, primarily in isolated, small headwater streams. About eight to nine percent of the occupied historic range is classified as "Conservation Populations." The Colorado River Cutthroat has been called one of the most spectacular of the cutthroat trout and one of the most beautiful fish in North America.
