Grand Canyon Releases Plan to Aid Native Fish

FLAGSTAFF, Ariz. (AP) -- The Colorado River through the Grand Canyon and its tributaries used to be home to eight native fish species.

That was before Glen Canyon Dam was built near the Arizona-Utah border, making the environment less-than-ideal for spawning.

Officials with the National Park Service say they want to make sure native fish still present have the best chance for survival.

A 20-year fisheries management plan released this week puts in place measures to protect those fish and ensure that anglers have plenty of non-native rainbow trout to catch below the dam.

Biologists and volunteers would boost populations of endangered humpback chub by placing them in select Grand Canyon creeks. They'll also study habitat for the endangered razorback sucker on the far western edge of the national park near Lake Mead.



Callville Bay Cleanup Planned for Saturday

Callville Bay Cleanup Planned for Saturday

People will get a chance to help clean up a portion of Lake Mead this weekend in the annual Clean-Up Day at Callville Bay Resort and Marina.

Forever Resorts and the National Park Service will host the cleanup effort Saturday. Registration starts at 8 a.m. The clean-up will be from 9 a.m. through noon. A barbecue lunch for volunteers will follow.

People who want to volunteer should wear layered clothing, closed-toe shoes, sunglass or hat and sunscreen. Tools and garbage bags will be provided.

Everyone who volunteers will get a T-shirt and be entered in a raffle for prizes.

More than 21,000 pounds of debris have been collected over the last five clean-up days at Callville Bay. 

Feds Flood Grand Canyon to Distribute Sediment

PAGE, Ariz. (AP) -- The Department of the Interior has started another high-flow release from Glen Canyon Dam in northern Arizona.

It's the second release under an innovative science-based experimental plan approved in May 2012.

The goal of the releases is to help restore the environment in Grand Canyon National Park and Glen Canyon National Recreation Area while continuing to meet water and power needs and allowing continued scientific experimentation and monitoring on the Colorado River.

The 96-hour-release will pick up enough sand from river channels to fill a building as big as a football field and as tall as the Washington Monument, all the way to the brim.

The hundreds of thousands of tons of sediment from river channels will be re-deposited along downstream reaches as sandbars and beaches along the Colorado River.

Bighorn Sheep from Key Boulder City Herd had Viral Pneumonia

Bighorn Sheep from Key Boulder City Herd had Viral Pneumonia

Biologists are very concerned after finding viral pneumonia in the herd of bighorn sheep that call Boulder City home.

An ailing bighorn sheep caught and killed by wildlife officials in a Boulder City park two weeks ago has tested positive for viral pneumonia, but it does not appear to be a particularly lethal strain.

Fundraising for Colorado River Launches in Arizona

Fundraising for Colorado River Launches in Arizona

PHOENIX (AP) -- A coalition of environmental groups is launching a fundraising drive to restore part of the overtaxed Colorado River that has become more desert than delta.

Conservationists from Mexico and the U.S., including actor Robert Redford, will gather Saturday at the Arizona Science Center in Phoenix for a "low-water-use" gala.

Redford will give remarks as well as screen "Watershed," a documentary on the river system produced by Redford and his son Jamie Redford.

The director of the Colorado River Campaign, Gary Wockner, says there's an opportunity to restore the river delta, which lies in Mexico and once had 2 million acres of wetlands.

Looming shortages are predicted on the river serving some 40 million people in California, Arizona, Colorado, Nevada, Utah, New Mexico and Wyoming. Mexico also has a stake. 

Lake Mead Offering Climate Change Workshop for Teachers

Lake Mead Offering Climate Change Workshop for Teachers

Lake Mead National Recreation Area is just one of three national parks that has been selected to be part of a teacher education program.

The Parks Climate Challenge program offers local teachers training in climate change by using the national parks as a living classroom.

Through a grant from the National Parks Foundation, the Lake Mead Institute will be offering the "Climate Change in the Desert Southwest" workshop as a two-credit graduate course in September. The course is recommended for 4th, 5th, middle and high school teachers.

The workshop will include information on the impact climate change is having on the desert southwest and activities that teachers can use in their classrooms to teach their students.
