- 20 May 2013 | By USGS | 106
A new U.S. Geological Survey study documents that the Nation's aquifers are being drawn down at an accelerating rate. Groundwater Depletion in the United States (1900-2008) comprehensively evaluates long-term cumulative depletion volumes in 40 separate aquifers (distinct underground water storage areas) in the United States, bringing together reliable information from previous references and from new analyses.

- 10 May 2013 | By Ordnance Survey | 135
National mapping authority Ordnance Survey, has released a new product which maps watercourses across Scotland including the highlands and islands, to help local authorities manage flood risk effectively and reduce the impact of flooding incidents. OS MasterMap Networks – Water Layer will be used to improve scientific understanding of water flows and water quality reporting under the statutory EU Water Framework Directive.
Warmer Springs Causing Loss of Snow Cover throughout the Rocky Mountains

- 14 May 2013 | By USGS | 159
Warmer spring temperatures since 1980 are causing an estimated 20 percent loss of snow cover across the Rocky Mountains of western North America, according to new research from the U.S. Geological Survey. The new study builds upon a previous USGS snowpack investigation which showed that, until the 1980s, the northern Rocky Mountains experienced large snowpacks when the central and southern Rockies experienced meager ones, and vice versa. Yet, since the 1980s, there have been simultaneous snowpack declines along the entire length of the Rocky Mountains, and unusually severe declines in the north.
Decades-old Nitrate Found to Affect Stream Water Quality
- Details
- 07 May 2013 | By USGS | 115
USGS hydrologic researchers have found that the movement of nitrate through groundwater to streams can take decades to occur. This long lag time means that changes in the use of nitrogen-based fertilizer (the typical source of nitrate) — whether the change is initiation, adjustment, or cessation — may take decades to be fully observed in streams, according to a recent study published in the journal Environmental Science and Technology.
