National Water-Use at Lowest Levels since before 1970

Wed, 11/05/2014 - 09:16
Summary: Water use across the country reached its lowest recorded level in nearly 45 years. According to a new USGS report, about 355 billion gallons of water per day (Bgal/d) were withdrawn for use in the entire United States during 2010.

Water use across the country reached its lowest recorded level in nearly 45 years. According to a new USGS report, about 355 billion gallons of water per day (Bgal/d) were withdrawn for use in the entire United States during 2010.

This represents a 13 percent reduction of water use from 2005 when about 410 Bgal/d were withdrawn and the lowest level since before 1970.

“Reaching this 45-year low shows the positive trends in conservation that stem from improvements in water-use technologies and management,” said Mike Connor, deputy secretary of the Interior.  “Even as the U.S. population continues to grow, people are learning to be more water conscious and do their part to help sustain the limited freshwater resources in the country.”

In 2010, more than 50 percent of the total withdrawals in the United States were accounted for by 12 states in order of withdrawal amounts: California, Texas, Idaho, Florida, Illinois, North Carolina, Arkansas, Colorado, Michigan, New York, Alabama and Ohio.

California accounted for 11 percent of the total withdrawals for all categories and 10 percent of total freshwater withdrawals for all categories nationwide. Texas accounted for about 7 percent of total withdrawals for all categories, predominantly for thermoelectric power, irrigation and public supply.

Florida had the largest saline withdrawals, accounting for 18 percent of the total in the country, mostly saline surface-water withdrawals for thermoelectric power. Oklahoma and Texas accounted for about 70 percent of the total saline groundwater withdrawals in the United States, mostly for mining.

“Since 1950, the USGS has tracked the national water-use statistics,” said Suzette Kimball, acting USGS director. “By providing data down to the county level, we are able to ensure that water resource managers across the nation have the information necessary to make strong water-use and conservation decisions.”

Water withdrawn for thermoelectric power was the largest use nationally, with the other leading uses being irrigation, public supply and self-supplied industrial water, respectively. Withdrawals declined in each of these categories. Collectively, all of these uses represented 94 percent of total withdrawals from 2005-2010.

  • Thermoelectric power declined 20 percent, the largest percent decline.
  • Irrigation withdrawals (all freshwater) declined 9 percent.
  • Public-supply withdrawals declined 5 percent.

Self-supplied industrial withdrawals declined 12 percent. 

A number of factors can be attributed to the 20 percent decline in thermoelectric-power withdrawals, including an increase in the number of power plants built or converted since the 1970’s that use more efficient cooling-system technologies, declines in withdrawals to protect aquatic habitat and environments, power plant closures and a decline in the use of coal to fuel power plants.

"Irrigation withdrawals in the United States continued to decline since 2005, and more croplands were reported as using higher-efficiency irrigation systems in 2010,” said Molly Maupin, USGS hydrologist. “Shifts toward more sprinkler and micro-irrigation systems nationally and declining withdrawals in the West have contributed to a drop in the national average application rate from 2.32 acre-feet per acre in 2005 to 2.07 acre-feet per acre in 2010."

For the first time, withdrawals for public water supply declined between 2005 and 2010, despite a 4 percent increase in the nation’s total population. The number of people served by public-supply systems continued to increase and the public-supply per capita use declined to 89 gallons per day in 2010 from 100 gallons per day in 2005.

Declines in industrial withdrawals can be attributed to factors such as greater efficiencies in industrial processes, more emphasis on water reuse and recycling, and the 2008 U.S. recession, resulting in lower industrial production in major water-using industries.

In a separate report, USGS estimated thermoelectric-power withdrawals and consumptive use for 2010, based on linked heat- and water-budget models that integrated power plant characteristics, cooling system types and data on heat flows into and out of 1,290 power plants in the United States. These data include the first national estimates of consumptive use for thermoelectric power since 1995, and the models offer a new approach for nationally consistent estimates.

In August, USGS released the 2010 water-use estimates for California in advance of the national report. The estimates showed that in 2010, Californians withdrew an estimated total of 38 Bgal/day, compared with 46 Bgal/day in 2005.  Surface water withdrawals in the state were down whereas groundwater withdrawals and freshwater withdrawals were up. Most freshwater withdrawals in California are for irrigation.

The USGS is the world’s largest provider of water data and the premier water research agency in the federal government.

USGS and Canada Reach Confluence in Monitoring Streamflow

Tue, 11/04/2014 - 07:56
Summary: In a joint effort, the U.S. Geological Survey and the Water Survey of Canada (WSC) have produced the North America WaterWatch (NAWW), an online website that displays streamflow conditions throughout much of North America. 

Contact Information:

Robert Mason, USGS ( Phone: 703-648-5305 ); Lingling Liu, WSC ( Phone: 613- 790-5151 ); Jon Campbell, USGS ( Phone: 703-648-4180 );



In a joint effort, the U.S. Geological Survey and the Water Survey of Canada (WSC) have produced the North America WaterWatch (NAWW), an online website that displays streamflow conditions throughout much of North America. 

The site provides a fast, easy-to-use, cartographically-based, central web interface for users to access real-time streamflow conditions for both Canada and the United States. NAWW can be accessed online in both English and French 

"North America WaterWatch delivers easily understandable maps and graphics of streamflow conditions and, simultaneously, provides access to real-time and past streamflow data at thousands of streamgages in both nations,” said Jerad Bales, USGS Chief Scientist for Water. “The portal demonstrates the value of free exchange of water-data through interoperable web services, which is a major strategic focus of the USGS through open-water data activities."

The international collaboration was announced at the American Water Resources Association annual conference in Tysons Corner, Va. 

The NAWW site is arranged similarly to USGS Water Watch. Real-time instantaneous flow data are compared against historical daily streamflow percentiles at hydrometric monitoring stations. The stations are then color coded on the map to indicate current flow conditions in relation to normal conditions based on statistical thresholds (i.e. much below normal, below normal, normal, above normal, much above normal, and high). The timely availability of these streamflow indicators is vital to water managers and the general public, as the easily-recognized indicators constitute a direct link between hydrological field information and the assessment of risks. 

NAWW displays streamflow conditions in Canada for about 1000 real-time flow stations with more than 20 years of continuous streamflow records selected from three different data sources: the Water Survey of Canada (~ 850), Centre d'expertise hydrique du Québec (~ 100), and Alberta Environment (~ 60). Streamflow conditions in the United States are shown for roughly 8000 real-time flow stations. The data on the website are updated hourly; daily statistics are updated quarterly. 

The publishing of the NAWW website marks another milestone achieved through the cooperation between USGS and WSC.

New Maine Maps Feature National Scenic Trails

Mon, 10/27/2014 - 10:00
Summary: Newly released US Topo maps for Maine now feature segments of the Appalachian National Scenic Trail (A.T.)

Contact Information:

Mark Newell, APR ( Phone: 573-308-3850 ); Matt Robinson ( Phone: 304-535-4010 ); Larry Moore ( Phone: 303-202-4019 );



Newly released US Topo maps for Maine now feature segments of the Appalachian National Scenic Trail (A.T.).  Several of the 715 new US Topo quadrangles for the state now display parts of the A.T. along with other improved data layers. 

“Located within a day’s drive of 2/3rds of the U.S. population and open year-around to all visitors, the Appalachian Trail is America’s most readily accessible long-distance footpath,” said Matt Robinson, National Park Service GIS Specialist for the A.T. “Having its route accurately depicted on these new US Topo maps just makes it even more accessible to all who wish to explore this great resource.” 

The Appalachian National Scenic Trail is a public footpath that traverses more than 2,100 miles of the Appalachian mountains and valleys between Katahdin, Maine (northern terminus), and Springer Mountain, Georgia (southern terminus). It winds through scenic, wooded, pastoral, wild, and culturally resonant lands along this ancient mountain range. With more than 99% of the A.T.’s corridor on Federal or State land, it is the longest continuously marked, maintained, and publicly protected trail in the United States.

The USGS partnered with the National Park Service and the Appalachian Trail Conservancy to incorporate the trail data onto the Maine US Topo maps. This NST joins the Ice Age National Scenic Trail, the Pacific Northwest National Scenic Trail the North Country National Scenic Trail and the Pacific Crest National Scenic Trail as being featured on the new US Topo quads. The USGS hopes to eventually include all National Scenic Trails in The National Map products.

These new maps replace the first edition US Topo maps for Maine and are available for free download from The National Map and the USGS Map Locator & Downloader website.

To compare change over time, scans of legacy USGS topo maps, some dating back to the late 1800s, can be downloaded from the USGS Historical Topographic Map Collection

The National Trails System was established by Act of Congress in 1968. The Act grants the Secretary of Interior and the Secretary of Agriculture authority over the National Trails System. The Act defines four types of trails. Two of these types, the National Historic Trails and National Scenic Trails, can only be designated by Act of Congress. National scenic trails are extended trails located as to provide for maximum outdoor recreation potential and for the conservation and enjoyment of nationally significant scenic, historic, natural, and cultural qualities of the area through which such trails may pass.

There are 11 National Scenic Trails:
  • Appalachian National Scenic Trail
  • Pacific Crest National Scenic Trail
  • Continental Divide National Scenic Trail
  • North Country National Scenic Trail
  • Ice Age National Scenic Trail
  • Potomac Heritage National Scenic Trail
  • Natchez Trace National Scenic Trail
  • Florida National Scenic Trail
  • Arizona National Scenic Trail
  • New England National Scenic Trail
  • Pacific Northwest National Scenic Trail

Revised Alabama Maps Feature New Design

Wed, 10/22/2014 - 10:00
Summary: US Topo maps now have a crisper, cleaner design - enhancing readability of maps for online and printed use Newly designed US Topo maps covering Alabama are now available online for free download

Mark Newell, APR ( Phone: 573-308-3850 ); Bob Davis ( Phone: 573-308-3554 );



US Topo maps now have a crisper, cleaner design - enhancing readability of maps for online and printed use. Map symbols are easier to read over the digital aerial photograph layer whether the imagery is turned on or off. Improvements to symbol definitions (color, line thickness, line symbols, area fills), layer order, and annotation fonts are additional features of this latest update. The maps also have transparency for some features and layers to increase visibility of multiple competing layers.

This new design was launched earlier this year and is now part of the new US Topo quadrangles for Alabama (840 maps), replacing the first edition US Topo maps for the states.

"Users in our state are very excited about the three year revision cycle of the US Topo maps,” said George Heleine, the Geospatial Liaison for Alabama and Mississippi.  “The Alabama Department of Transportation says that due to increased growth within the state, updated maps will significantly increase their utility across all disciplines within State Government”. 

US Topo maps are updated every three years. The initial round of the 48 conterminous states coverage was completed in September of 2012.  Hawaii and Puerto Rico maps have recently been added. Nearly 1,000 new US Topo maps for Alaska have been added to the USGS Map Locator & Downloader, but will take several years to complete.

Re-design enhancements and new features:

  • Crisper, cleaner design improves online and printed readability while retaining the look and feel of traditional USGS topographic maps
  • New functional road classification schema has been applied
  • A slight screening (transparency) has been applied to some features to enhance visibility of multiple competing layers
  • Updated free fonts that support diacritics
  • New PDF Legend attachment
  • Metadata formatted to support multiple browsers
  • New shaded relief layer for enhanced view of the terrain
  • Military installation boundaries, post offices and cemeteries
  • The railroad dataset is much more complete

The previous versions of US Topo maps for these states, published in 2011, can still be downloaded from USGS web sites. Also, scanned images of older topographic maps from the period 1884-2006 can be downloaded from the USGS Historical Topographic Map Collection. These scanned images of legacy paper maps are available for free download from The National Map and the USGS Map Locator & Downloader website

US Topo maps are created from geographic datasets in The National Map, and deliver visible content such as high-resolution aerial photography, which was not available on older paper-based topographic maps. The new US Topo maps also provide modern technical advantages that support wider and faster public distribution and on-screen geographic analysis tools for users. The new digital electronic topographic maps are delivered in GeoPDF ® image software format and may be viewed using Adobe Reader, available as a no-cost download.

Interior, Agriculture Departments Partner to Measure Conservation Impacts on Water Quality

Tue, 10/21/2014 - 09:57
Summary: The United States Department of the Interior (DOI) and the U.S. Department of Agriculture (USDA) announced a new partnership agreement today that will provide a clearer picture of the benefits of farmers' conservation practices on the quality of our Nation's water

Contact Information:

Ethan Alpern ( Phone: 703-648-4406 ); Michael Woodside ( Phone: 615-837-4706 );



ALTON, Ill., Oct. 21, 2014—The United States Department of the Interior (DOI) and the U.S. Department of Agriculture (USDA) announced a new partnership agreement today that will provide a clearer picture of the benefits of farmers' conservation practices on the quality of our Nation's water.  Working together, USDA's NRCS and DOI's USGS will quantify the benefits of voluntary agricultural practices at a watershed scale.  This information will strengthen the effectiveness of state and federal nutrient reduction strategies while protecting the privacy of individual farmers.  The agreement was announced at the Mississippi River Gulf of Mexico Watershed Nutrient Task Force Meeting.

“On a voluntary basis, the agricultural community has put extensive effort into the management of nutrients and reducing runoff into waterways. This collaboration will help evaluate the impact of farmers’ conservation efforts on improving water quality,” said Ann Mills, USDA’s deputy under secretary for Natural Resources and Environment.

Mills said when hundreds of farms take action in one watershed, it can make a difference—it can help prevent an algae bloom downstream or lessen the need for water treatment plants to treat for nitrates.

The U.S. Geological Survey will now use Natural Resources Conservation Service data on conservation work to factor into its surface water quality models, which track how rivers receive and transport nutrients from natural and human sources to downstream reservoirs and estuaries. This information will help provide a more accurate picture of the conservation systems in the watershed that contribute to water quality improvement and will provide crucial information for voluntary nutrient management strategies and watershed planning.

“This agreement will allow NRCS and USGS to combine resource management capabilities with science, and will give us the information we need to prioritize the most effective conservation strategies so that we can improve the quality of streams throughout the Mississippi River Basin,” said Lori Caramanian, DOI deputy assistant secretary for Water and Science.

Working together, NRCS and USGS will develop conservation intensity data sets that reflect the value of conservation actions, but do not reveal private information about individual farms, ranches or forests. Protecting the trust relationship between NRCS and farmers and their private information protected by law is vital to the continued success of voluntary conservation on private lands.

“We know our farmers are doing great work to protect our natural resources. Our goal with this partnership is to be able to better recognize these achievements and provide conservation and water quality management communities with science-based information for improving water quality,” Mills said. “Farmers invest heavily in conservation systems to improve water quality, and we want to aid their decisions with the best science and information available.”

The conservation intensity products developed through the agreement will provide a uniform representation of conservation activities for use in water quality assessments at local, regional and national scales. Technical assistance providers will therefore have the assurance that they are using consistent and accurate information on conservation activities and a common platform for discussing conservation benefits.

Nutrient runnoff from many different sources, including urban areas and industry, impacts our nation’s waterways. By providing science-based information, NRCS and USGS can help farmers decrease nutrient runoff and improve water quality for their communities and downstream.

ALTON, Ill., Oct. 21, 2014—The United States Department of the Interior (DOI) and the U.S. Department of Agriculture (USDA) announced a new partnership agreement today that will provide a clearer picture of the benefits of farmers' conservation practices on the quality of our Nation's water.  Working together, USDA's NRCS and DOI's USGS will quantify the benefits of voluntary agricultural practices at a watershed scale.  This information will strengthen the effectiveness of state and federal nutrient reduction strategies while protecting the privacy of individual farmers.  The agreement was announced at the Mississippi River Gulf of Mexico Watershed Nutrient Task Force Meeting.

“On a voluntary basis, the agricultural community has put extensive effort into the management of nutrients and reducing runoff into waterways. This collaboration will help evaluate the impact of farmers’ conservation efforts on improving water quality,” said Ann Mills, USDA’s deputy under secretary for Natural Resources and Environment.

Mills said when hundreds of farms take action in one watershed, it can make a difference—it can help prevent an algae bloom downstream or lessen the need for water treatment plants to treat for nitrates.

The U.S. Geological Survey will now use Natural Resources Conservation Service data on conservation work to factor into its surface water quality models, which track how rivers receive and transport nutrients from natural and human sources to downstream reservoirs and estuaries. This information will help provide a more accurate picture of the conservation systems in the watershed that contribute to water quality improvement and will provide crucial information for voluntary nutrient management strategies and watershed planning.

“This agreement will allow NRCS and USGS to combine resource management capabilities with science, and will give us the information we need to prioritize the most effective conservation strategies so that we can improve the quality of streams throughout the Mississippi River Basin,” said Lori Caramanian, DOI deputy assistant secretary for Water and Science.

Working together, NRCS and USGS will develop conservation intensity data sets that reflect the value of conservation actions, but do not reveal private information about individual farms, ranches or forests. Protecting the trust relationship between NRCS and farmers and their private information protected by law is vital to the continued success of voluntary conservation on private lands.

“We know our farmers are doing great work to protect our natural resources. Our goal with this partnership is to be able to better recognize these achievements and provide conservation and water quality management communities with science-based information for improving water quality,” Mills said. “Farmers invest heavily in conservation systems to improve water quality, and we want to aid their decisions with the best science and information available.”

The conservation intensity products developed through the agreement will provide a uniform representation of conservation activities for use in water quality assessments at local, regional and national scales. Technical assistance providers will therefore have the assurance that they are using consistent and accurate information on conservation activities and a common platform for discussing conservation benefits.

Nutrient runnoff from many different sources, including urban areas and industry, impacts our nation’s waterways. By providing science-based information, NRCS and USGS can help farmers decrease nutrient runoff and improve water quality for their communities and downstream.
