Mercury's surface in "enhanced color," a color scheme created to emphasize color differences. This is not what Mercury would look like to the human eye, but by applying mathematical analysis to images, color differences can be accentuated beyond those visible to a person.
Mount Rushmore National Memorial under construction.
The workers had to endure conditions that varied from blazing hot to bitterly cold and windy. Each day they climbed 700 stairs to the top of the mountain to punch-in on the time clock. Then 3/8 inch thick steel cables lowered them over the front of the 500-foot face of the mountain in a "bosun chair." Despite the dangers, no one was killed during the project.
Otters in Glacier Bay National Park and Preserve, Alaska.
The sea otter population of Glacier Bay has increased dramatically in the past 20 years. Ecologists consider sea otters a keystone species here. Otters consume vast quantities of clams, urchins, crabs, and other invertebrates and their presence creates ripples through the ecosystem. NPS photo.
Every day someone like you becomes a wildland wildfire fighter, a teacher, a trail-builder, a museum curator, or a park ranger. Discover your opportunities in national parks. Come to play. Come to learn. Come to serve. Develop your environmental leadership skills. Find a job. Be the next generation to preserve and protect these great places.
With more than 80% of Americans living in urban areas, urban parks are more important than ever. The father of American landscape architecture, Frederick Law Olmsted, said of urban parks:
It is one great purpose of the Park to supply to the hundreds of thousands of tired workers, who have no opportunity to spend their summers in the country, a specimen of God's handiwork that shall be to them, inexpensively, what a month or two in the White Mountains or the Adirondacks is, at great cost, to those in easier circumstances.
Interior Announces Increased Water Supply Allocations in California
Office of the Secretary
Central Valley Water Supply Continues to Improve
Last edited 4/25/2016
WASHINGTON, D.C. —Secretary of the Interior Ken Salazar today announced that the Bureau of Reclamation's 2010 Central Valley Project Water Supply allocations have increased throughout the valley as a result of improved hydrologic conditions as they existed as of April 1, 2010 and as reflected in the California Department of Water Resources (DWR) April 2010 snow survey and runoff forecast.
“For the second consecutive month, we are accelerating our reporting of updated allocations, in an effort to get the best available information to our contractors as quickly as possible to aid in their planning decisions for the upcoming season,” stated Secretary of the Interior Ken Salazar.
Compared to the previous allocation and using a conservative forecast (generally referred to as the 90-percent exceedance forecast):
• The allocation for Municipal and Industrial (M&I) water service contractors north of the Delta, including American River and Contra Costa M&I contractors, is 100 percent—up from 75 percent
• M&I water service contractors south of the Delta remain at 75 percent allocation.
• Agricultural water service contractors north of the Delta are allocated 100 percent—up from 50 percent.
• Agricultural water service contractors south of the Delta are allocated 30 percent—up from 25 percent.
• Friant Division agricultural water service contractors' allocation of Class 2 water supply increases to 15 percent—up from 10 percent; Class 1 allocation remains at 100 percent.
• Eastside Division agricultural contractors' (Stanislaus River) allocation remains at 100 percent of their contract quantities (155,000 acre-feet).
• The allocation for settlement contractors with claims to senior water rights along the Sacramento and San Joaquin Rivers remains at 100 percent of their contract quantities (approximately 2.4 million acre-feet).
• Wildlife refuges' allocation north and south of the Delta remains at 100 percent of their “Level 2” water (approximately 400,000 acre-feet).
“Serious water supply challenges still exist for South-of-Delta agricultural contractors in part as a result of 3 consecutive years of drought, early water year 2010 dry conditions, as well as operational constraints on the CVP to address water quality and fish species of concern,” said Secretary Salazar. “As I announced in March of this year, we are committed to efforts to secure an additional 8 to 10 percent supply for agricultural contractors south of the Delta. We are expecting that up to 150,000 to 200,000 acre-feet can be secured to help supplement the South-of-Delta supplies.” These amounts represent new supplies for 2010 not previously available to the west side of the San Joaquin Valley.
“It is through our strong partnerships that we can best address the Central Valley Project's water supply challenges – both short term and long term. We, along with agencies and stakeholders, are fully engaged in developing water supply solutions while at the same time honoring conservation requirements and contract responsibilities.” added Secretary Salazar. “Working closely with Governor Schwarzenegger, Senators Feinstein and Boxer, Congressmen Miller, Costa, Cardoza, Thompson, and Grace Napolitano and other members of the Congressional delegation, plus all stakeholders, the Department is fully engaged in establishing solutions for a sustainable water supply in California.”
Water supply updates will be made monthly or more often as necessary based on new information throughout the precipitation season. Additional information, including the allocation table, and water supply updates are posted on the Mid-Pacific Region's website at http://www.usbr.gov/mp/PA/water/.
