By Marra, Bob California Secretary of Resources, Michael Chrisman, unveiled his preliminary plan to save and restore the Salton Sea to the Salton Sea Advisory Committee in Sacramento last week. The draft plan would create a 34,000-acre lake in the Sea's northern area, develop 62,000 acres of wildlife habitat in the south section and create 29,000 acres of brine sinks. In all, Chrisman's plan calls for a 45 percent reduction in the size of the actual Sea, including 109,000 acres of exposed...

An epic drought during the mid-1100s dwarfs any drought previously documented for a region that includes areas of Arizona, Colorado, New Mexico, Utah and Wyoming. The six-decade-long drought was remarkable for the absence of very wet years.  At the core of the drought was a period of 25 years in which Colorado River flow averaged 15 percent below normal. The new tree-ring-based reconstruction documents the year-by-year natural variability of streamflows in the upper Colorado River basin...

By Chris Woodka, The Pueblo Chieftain, Colo. Dec. 4--A water developer with plans to pipe Arkansas Valley water to the Denver metro area is playing a waiting game, and it may be years before the company seeks court approval, let alone build a pipeline. "It's a long-term project, no question," said Mark Harding, president of Thornton-based Pure Cycle Corp. Pure Cycle completed its purchase of Fort Lyon Canal farms and water rights from High Plains A&M in late August, but there is no...

PHOENIX -- Great views "” and plenty of goosebumps for those afraid of heights. An American Indian tribe with land along the Grand Canyon is planning to build a glass-bottomed walkway that will jut out 70 feet from the canyon's edge. The horseshoe-shaped skywalk, expected to open in January, is part of the Hualapai Tribe's $40 million effort to turn 1,000 acres of reservation land into a tourist destination that will also feature an Indian village and Western-themed town. The tribe's...

When it's dry, it's dry all over, according to a new analysis of more than 400 years of annual streamflow in the Upper Colorado and Salt and Verde river basins. By using data from tree rings, University of Arizona researchers conclude that water supply for those western rivers fluctuated in synchrony during periods of severe drought. The study goes back almost 800 years in the Salt-Verde basin and covers waterways from the states of Arizona, Colorado, New Mexico, Utah and Wyoming. The...

By Jim Christie SAN FRANCISCO (Reuters) - Nevada may be near a deal that would clear the way for one of the most ambitious water projects in the arid U.S. Southwest since the Hoover Dam -- a $5 billion network of wells and pipelines to bring water to the booming Las Vegas area. The agreement would allow the Southern Nevada Water Authority to proceed with its plan for a $5 billion water project, including 500 miles of pipelines, to meet the increasing demand for water in the booming Las...

GRAND CANYON NATIONAL PARK, Ariz. -- Mounted at about ear level on tripods, microphones are capturing the sound of quiet at the Grand Canyon. The four microphones are attached to sound level meters and computers that will later screen out all manmade sounds, such as the chatter of hikers, the rumble of cars and the buzz of sightseeing planes and helicopters. All that will be left will be the sounds of nature: the wind in the trees, the chirping of birds, for example. Park officials are...

HOOVER DAM, Nev. (AP) -- Water officials from California, Arizona and Nevada joined the federal government Monday in enacting a 50-year plan to protect the lower Colorado River and ensure states are able to get enough water and power from it. The $626 million agreement will benefit "the many important species, including humans, that rely on the Colorado River," said John Keys, commissioner of the Bureau of Reclamation, during a ceremony at the base of the massive Hoover Dam. The program,...

TUCSON, Ariz. (AP) -- The number of juvenile endangered fish recovered in the Colorado River declined dramatically after officials flooded the Grand Canyon in an effort to aid them and their fragile ecosystem. But scientists aren't sure what the fish decline means or why it happened. "We're trying to get the same answer," said Jeff Lovich, chief of the Grand Canyon Monitoring and Research Center in Flagstaff. "We don't know what their fate is." Following a 90-hour experimental water release...

Colorado Squawfish, Ptychocheilus lucius
2013-01-12 06:47:45

Formally known as the Colorado squawfish, this freshwater species is now called the Colorado pikeminnow. This fish was native to Arizona, California, Colorado, Nevada, New Mexico, Utah, and Wyoming, as well as portions of Mexico, but with the natural habitat changed by the damming of rivers and streams, this fish is now restricted to the Colorado Basin. Limited numbers of the Colorado squawfish still remain in the following rivers: Green, Gunnison, White, San Juan and Yampa; additionally it...

The Bonytail Chub (Gila elegans) is a species of freshwater fish native to certain areas of Arizona, California, Colorado, Nevada and Utah in the United States. Bonytail chub prefer backwaters with rocky or muddy bottoms and flowing pools, although they have been reported in swiftly moving water. They are mostly restricted to rocky canyons today, but were historically abundant in the wide downstream sections of rivers. It is the rarest of the endemic big-river fishes of the Colorado River. It...

The Woundfin (Plagopterus argentissimus) is a species of minnow endemic to the Virgin River of the southwestern United States. It is a slender, silvery minnow, with a flattened head and belly, long snout, leathery skin, and no scales. There are barbels on the corners of its lips, and its common name likely comes from the first spinous ray of its dorsal fin, which is sharp-pointed. Its maximum length is rarely more than 3 in (7.5 cm). Historically, the Woundfin occupied much of the lower...

  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
