The Bureau of Reclamation is releasing 3,600 cubic-feet-per-second from Olympus Dam to the Big Thompson River at the top of the Big Thompson Canyon. In addition, Reclamation is moving up to 550 cfs through facilities of the Colorado-Big Thompson project, keeping this water out of the Big Thompson River. Loveland, CO (PRWEB) September 12, 2013 The Bureau of Reclamation is releasing 3,600 cubic-feet-per-second from Olympus Dam to the Big Thompson River at the top of the Big Thompson Canyon....

Lessons From The Grand Canyon: Dams Destabilize River Food Webs

Cary Institute of Ecosystem Studies Managing fish in human-altered rivers is a challenge because their food webs are sensitive to environmental disturbance. So reports a new study in the journal Ecological Monographs, based on an exhaustive three-year analysis of the Colorado River in Glen and Grand Canyons. Food webs are used to map feeding relationships. By describing the structure of these webs, scientists can predict how plants and animals living in an ecosystem will respond to...

As the Colorado River winds through the Colorado Plateau's soft sedimentary strata, it picks up a tremendous amount of sediment. This sediment — which once left the river's waters so muddy that Spanish explorers christened it El Rio Colorado "the reddish river" — is a vital component to the unique ecosystems of the river. However, with the construction of the Hoover and Glen Canyon dams, which trap the sediment, the once-turbid waters have become a dazzling blue-green, signaling...

The U.S. Geological Survey says it will conduct scientific overflights at the Grand Canyon National Park in Arizona during the Memorial Day weekend. The overflights are designed to document the status of natural and cultural resources along the Colorado River below Glen Canyon Dam, officials said. Aerial photographs will be taken from two fixed-wing aircraft flying at an altitude of approximately 7,000 feet. Scientific overflights have been conducted as part of ongoing monitoring efforts...

Government officials plan to stage the third artificial flood in the Grand Canyon next month with hopes of reversing some of the negative effects experienced by the local ecosystem which were caused by the construction of a nearby dam.In 1963, the Glen Canyon Dam was built, and it completely changed the composition of the Colorado River and abruptly caused the extinction of four fish species, leaving two others currently in danger as the nearby beaches are eroding because sediment is being...

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...


Word of the Day
tesla
  • 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.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
