Fresh Water
Carp are various species of oily freshwater fish from the family Cyprinidae, a very large group of fish native to Europe and Asia. The cypriniformes are traditionally grouped with the Characiformes, Siluriformes, and Gymnotiformes to create the superorder Ostariophysi, since these groups share some common features. These features include being found predominantly in fresh water and possessing Weberian ossicles, an anatomical structure derived from the first five anterior-most vertebrae, and their corresponding ribs and neural crests. The third anterior-most pair of ribs is in contact with the extension of the labyrinth and the posterior with the swim bladder. The function is poorly understood, but this structure is presumed to take part in the transmission of vibrations from the swim bladder to the labyrinth and in the perception of sound, which would explain why the Ostariophysi have such a great capacity for hearing.
Fishing Waters
The Big Horn River in Thermopolis, Wyoming is the lesser known sister of the Big Horn in Fort Smith, Montana. An intimate tailwater which meanders through the farm fields and ranches ... moreof the Big Horn Basin, the river hosts Browns, Rainbows and Cutthroat trout. These fish grow large and fight hard, making for fun and challenging fly fishing. The Big Horn can be an excellent dry fly fishery - if conditions are favorable, trout will readily eat mayflies, cicadas, grasshoppers, crickets, ants and stoneflies during sometimes prolific hatches. Of course what happens on the surface is only part of the story. Trout fodder is abundant in the Big Horn, and often the best way to find fish is to go subsurface. The river fishes well in all seasons, and as we live right here in Thermopolis, we offer guided trips year round. A guided float trip is the best way to get the most out of this section of the Big Horn - due to water laws and private ownership, much of the river is not open to anchoring and wading. That being said, there are some spots where you could get out of the boat and wade fish if this is of interest to you. We invite you to come experience some of the best fishing Wyoming has to offer with one of the fishiest husband & wife teams in the West.
The Provo River features a premier blue ribbon trout fishery close to Utah's major cities. Brown and rainbow trout mature to record lengths in the Provo, with a most fish running 18 ... moreinches or bigger. In some areas the Provo offers 3,000 or more trout per mile. As a result, the waters of the Provo River provide exceptional recreation.

The Provo River flows through Utah County and Wasatch County, Utah. It rises in the Uinta Mountains at Washington Lake and flows about 70 miles southwest to Utah Lake at the city of Provo, Utah. The main branches of Provo River are the North Fork Provo River and the South Fork Provo River. In the Provo you'll find: Brown Trout, Common Carp, Cutthroat Trout, Mountain Whitefish, Rainbow Trout, Walleye, and White Bass.

The Truckee River is a stream in the U.S. states of California and Nevada. The river flows northeasterly and is 121 miles long. The Truckee is the sole outlet of Lake Tahoe and drains ... morepart of the high Sierra Nevada, emptying into Pyramid Lake in the Great Basin. Its waters are an important source of irrigation along its valley and adjacent valleys.

The Truckee River's source is the outlet of Lake Tahoe, at the dam on the northwest side of the lake near Tahoe City, California. It flows generally northeast through the mountains to Truckee, California, then turns sharply to the east and flows into Nevada, through Reno and Sparks and along the northern end of the Carson Range. At Fernley it turns north, flowing along the east side of the Pah Rah Range. It empties into the southern end of Pyramid Lake, a remnant of prehistoric Lake Lahontan, in northern Washoe County in the Pyramid Lake Indian Reservation.

The Truckee River's endorheic drainage basin is about 3,060 square miles (7,900 km2), of which about 2,300 square miles (6,000 km2) are in Nevada. The Middle Watershed is regarded as the 15 miles (24 km) of river and its tributaries from Tahoe City in Placer County, through the Town of Truckee in Nevada County, to the state line between Sierra and Washoe counties. The major tributaries to the Truckee River in California from the Lake Tahoe outlet and heading downstream include: Bear Creek, Squaw Creek, Cabin Creek, Pole Creek, Donner Creek, Trout Creek, Martis Creek, Prosser Creek, the Little Truckee River, Gray Creek, and Bronco Creek. Major lakes and reservoirs in the California part of the watershed include Lake Tahoe, Donner Lake, Independence Lake, Webber Lake, Boca Reservoir, Stampede Reservoir, Prosser Creek Reservoir, and Martis Creek Reservoir. In the Lower Watershed, Steamboat Creek, which drains Washoe Lake, is the major tributary to the Truckee River.
