Boulder Creek (Colorado)
Boulder Creek is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed March 25, 2011 creek draining the Rocky Mountains to the west of Boulder, Colorado, as well as the city itself and surrounding plains. Route The creek is formed by two main tributaries rising along the Continental Divide: North and Middle Boulder Creek; and later joined by South Boulder Creek. North Boulder Creek forms in a valley between Navajo Peak and Arikaree Peak on the Continental Divide, in the Green Lakes chain of lakes. The creek flows past the community of Switzerland Park to join Middle Boulder Creek. Middle Boulder Creek rises as two forks from the Continental Divide: the North Fork rises in a cirque below Mount Neva and flows to the South Fork. The South Fork rises at Rollins Pass on the Continental Divide and flows to the North Fork. From the junction of the two forks, Middle Boulder Creek, long, flows east through the towns of ...

River Mouth
A river mouth is where a river flows into a larger body of water, such as another river, a lake/reservoir, a bay/gulf, a sea, or an ocean. At the river mouth, sediments are often deposited due to the slowing of the current reducing the carrying capacity of the water. The water from a river can enter the receiving body in a variety of different ways. The motion of a river is influenced by the relative density of the river compared to the receiving water, the rotation of the earth, and any ambient motion in the receiving water, such as tides or seiches. If the river water has a higher density than the surface of the receiving water, the river water will plunge below the surface. The river water will then either form an underflow or an interflow within the lake. However, if the river water is lighter than the receiving water, as is typically the case when fresh river water flows into the sea, the river water will float along the surface of the receiving water as an overflow.

Creek Chub (Semotilus Atromaculatus)
''Semotilus'' is the genus of creek chubs, ray-finned fish in the family Cyprinidae. The term "creek chub" is sometimes used for individual species, particularly the common creek chub, ''S. atromaculatus''. The creek chub species of minnows can grow from 6 to 10 inches. They can be found in the United States and Canada in any small stream or creek. They hide under small rocks for protection. They have a small black spot on the dorsal fin for easy identification.

Semotilus Atromaculatus
''Semotilus atromaculatus'', known as the creek chub or the common creek chub, is a small minnow, a freshwater fish found in the eastern US and Canada. Differing in size and color depending on origin of development, the creek chub can usually be defined by a dark brown body with a black lateral line spanning horizontally across the body. It lives primarily within streams and rivers. Creek Chubs attain lengths of 2-6 inches with larger specimens of up to 12 inches possible. The genus name ''Semotilus'' derives from the Greek word ''sema'' (also known as dorsal fin), and ''atromaculatus'' comes from the Latin word "black spots". Distribution and habitat A fish which can withstand many different environments, the creek chub's current range is the eastern two-thirds of the US and southeastern Canada. It can quickly adapt to different extreme environments, and can live on many different foods. Documented to span throughout the Great Lakes surrounding Wisconsin, and into Minnesota, t ...

White Sucker, Catostomus Commersonii
White is the lightest color and is achromatic (having no hue). It is the color of objects such as snow, chalk, and milk, and is the opposite of black. White objects fully reflect and scatter all the visible wavelengths of light. White on television and computer screens is created by a mixture of red, blue, and green light. The color white can be given with white pigments, especially titanium dioxide. In ancient Egypt and ancient Rome, priestesses wore white as a symbol of purity, and Romans wore white togas as symbols of citizenship. In the Middle Ages and Renaissance a white unicorn symbolized chastity, and a white lamb sacrifice and purity. It was the royal color of the kings of France, and of the monarchist movement that opposed the Bolsheviks during the Russian Civil War (1917–1922). Greek and Roman temples were faced with white marble, and beginning in the 18th century, with the advent of neoclassical architecture, white became the most common color of new churches ...

White Sucker
The white sucker (''Catostomus commersonii)'' is a species of freshwater cypriniform fish inhabiting the upper Midwest and Northeast in North America, but it is also found as far south as Georgia and as far west as New Mexico. The fish is commonly known as a "sucker" due to its fleshy, papillose lips that suck up organic matter and '' aufwuchs'' from the bottom of rivers and streams. Other common names for the white sucker include bay fish, brook sucker, common sucker, and mullet. The white sucker is often confused with the longnose sucker (''C. catostomus''), because they look very similar. Etymology The specific name, ''commersonii'', is in honor of French naturalist Philibert Commerson. Description The white sucker is a long, round-bodied fish with a dark green, grey, copper, brown, or black back and sides and a light underbelly. The fish also has typical features of primitive Cypriniformes fishes, such as a homocercal tail, cycloid scales, and dorsal, pectoral, and pelvic f ...

Etheostoma Exile - Iowa Darter
''Etheostoma'' is a genus of small freshwater fish in the family Percidae native to North America. Most are restricted to the United States, but species are also found in Canada and Mexico. They are commonly known as darters, although the term "darter" is shared by several other genera. Many can produce alarm pheromones that serve to warn nearby fish in case of an attack.Smith, R.J.F. (1992): Alarm signals in fishes. ''Reviews in Fish Biology and Fisheries, 2 (1): 33-63.'' Species The 157 recognized species in this genus are: * ''Etheostoma acuticeps'' R. M. Bailey, 1959 (sharphead darter) * ''Etheostoma akatulo'' Layman & Mayden, 2009 (bluemask darter) * '' Etheostoma artesiae'' ( O. P. Hay, 1881) (redspot darter) * '' Etheostoma asprigene'' ( S. A.

Etheostoma Exile
''Etheostoma exile'', the Iowa darter, is a species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. It is, along with about 17 other species of darters, is native to the lakes and streams of Iowa. In some parts of its range, the Iowa darter is also known as the weed darter, red-sided darter, or yellowbelly. Iowa darters, like many other darters, are about 2–3 in (51–76 mm) in length and may be easily confused with other darters of similar color. Range Native distribution of the Iowa darter extends north to central Canada, east to New York, and south to central Illinois, and the species is particularly common in the western Great Lakes drainages and Iowa. Western populations are distributed patchily in Colorado, Wyoming, Montana, and Alberta. They are native in Colorado only in the South Platte River drainage, but recent research has also placed them in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Colorado
Colorado (, other variants) is a state in the Mountain West subregion of the Western United States. It encompasses most of the Southern Rocky Mountains, as well as the northeastern portion of the Colorado Plateau and the western edge of the Great Plains. Colorado is the eighth most extensive and 21st most populous U.S. state. The 2020 United States census enumerated the population of Colorado at 5,773,714, an increase of 14.80% since the 2010 United States census. The region has been inhabited by Native Americans and their ancestors for at least 13,500 years and possibly much longer. The eastern edge of the Rocky Mountains was a major migration route for early peoples who spread throughout the Americas. "''Colorado''" is the Spanish adjective meaning "ruddy", the color of the Fountain Formation outcroppings found up and down the Front Range of the Rocky Mountains. The Territory of Colorado was organized on February 28, 1861, and on August 1, 1876, U.S. President Ulyss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fly Fishing
Fly fishing is an angling method that uses a light-weight lure—called an artificial fly—to catch fish. The fly is cast using a fly rod, reel, and specialized weighted line. The light weight requires casting techniques significantly different from other forms of casting. The flies may resemble natural invertebrates, bait-fish, or other food organisms. Fly fishing can be done in fresh or saltwater. North Americans usually distinguish freshwater fishing between cold-water species (trout, salmon) and warm-water species, notably bass. In Britain, where natural water temperatures vary less, the distinction is between game fishing for trout and salmon versus coarse fishing for other species. Techniques for fly fishing differ with habitat (lakes and ponds, small streams, large rivers, bays and estuaries, and open ocean.) Author Izaak Walton called fly fishing "The Contemplative Man's Recreation". Overview In fly fishing, fish are caught by using artificial flies that ar ...
