A rugged, whitewater river flowing northward through deep canyons, the New River is among the oldest rivers on the continent. New River Gorge National River in West Virginia encompasses over 70,000 acres of land along the New River, is rich in cultural and natural history, and offers an abundance of scenic and recreational opportunities.
Big Southern Butte is one of two domes rising from a sea of basalt near the center of the eastern Snake River Plain in Idaho. The butte is one of the largest volcanic domes in the world, but at 300,000 years old it is also one of the youngest. Hikers who trek to the 7,550-foot high summit are rewarded with spectacular panoramic views. Photo by Devin Englestead, BLM Upper Snake Wildlife Biologist.

Established in November 22, 1939, the refuge has provided a critical stopover and wintering spot for thousands of sandhill cranes, geese and other waterfowl for 75 years. Bosque del Apache's sandhill crane population has multiplied from 18 birds in the 1840s to more than 20,000 birds today. Photo by Kim Hang Dessoliers (www.sharetheexperience.org).
Monday's High-Flow Release from Glen Canyon Dam to Benefit Grand Canyon While Continuing Water Commitments
Office of the Secretary
PAGE, Ariz– On Monday, Nov. 11, Assistant Secretary of the Interior for Water and Science Anne Castle will join other officials to initiate a high-flow experimental release from Glen Canyon Dam—the second release under the science-based protocol adopted in May 2012 for more frequent high-flow experimental releases on the Colorado River.
Dam managers and resource specialists have determined that the right conditions exist to trigger a high flow that will mobilize the tremendous amount of sediment deposited by the Paria River since late July—nearly 1.5 million metric tons. Using dam operations to create a flood that mimics pre-dam natural flooding in the watershed, the sediment carried and deposited downstream in Grand Canyon National Park will build sandbars that provide key wildlife habitat for animals and fish, create recreational opportunities for the public, and protect archaeological resources.
The high flows will not change the total annual delivery of water from Lake Powell to Lake Mead; they will simply slightly modify the timing of delivery. The available sediment volume is approximately three times greater than it was in the fall of 2012.
