Alaska North Slope LiDAR
High-resolution light detection and ranging (lidar) elevation data were acquired along the north coast of Alaska between 2009 and 2012. The lidar acquisition, from Icy Cape, Alaska to the United States/Canadian border, comprised approximately 11,000 km2. The airborne lidar data were acquired in support of the U.S. Geological Survey...
Assessment of Sediment Quality and Volume behind Enloe Dam
The Issue:
The Enloe Dam, a 100-yr old structure on the Similkameen River in Washington State, has not produced hydropower since 1958 and options are being considered for potential removal of the dam. The concentrations of sediment contaminants (primarily trace elements from a long history of mining and smelting operations in the US and Canada) trapped by Enloe Dam are...
Coastal Climate Impacts
The impacts of climate change and sea-level rise around the Pacific and Arctic Oceans can vary tremendously. Thus far the vast majority of national and international impact assessments and models of coastal climate change have focused on low-relief coastlines that are not near seismically active zones. Furthermore, the degree to which extreme waves and wind will add further stress to coastal...
Climate impacts to Arctic coasts
The Arctic region is warming faster than anywhere else in the nation. Understanding the rates and causes of coastal change in Alaska is needed to identify and mitigate hazards that might affect people and animals that call Alaska home.
Eyes on Earth Episode 39 – Brazil’s Water Use
Eyes on Earth is a podcast on remote sensing, Earth observation, land change and science, brought to you by the USGS Earth Resources Observation and Science (EROS) Center. In this episode, we hear how Landsat aids water use studies in Brazil.
2012 SPARROW Models for the Northeast: Total Phosphorus, Total Nitrogen, Suspended Sediment, and Streamflow
The 2012 SPAtially Referenced Regression On Watershed attributes (SPARROW) Models measure the damaging contaminants of phosphorus, nitrogen, and suspended sediment in streamflow throughout the Northeast United States. Through various types of watershed management practices, loads of nutrients and suspended sediment are significantly reduced within the stream network in impounded reaches, and...

From Gage to Page: A Look Into How USGS Helps You Know the Flow
Knowing the streamflow of a river is important for many. For example, irrigators need to know how the water can be allocated to fields, boaters need to know if the river is safe to float, and municipalities need to know how much supply will be at their intakes.
