Grass Carp in Lake Erie
Grass Carp, commonly used in aquaculture to control plant growth, escaped captivity in the Mississippi River and have been in the Great Lakes since 1975. Spawning surveys have documented spawning since 2015 in the Sandusky River leading to expanded surveys and an effort to confine reproduction to the western part of Lake Erie.
Science Support Program and Quick Response Program
This is a nation-wide collaborative program, supported by the USGS Ecosystems Mission Area, through which USGS and U.S. Fish and Wildlife Service staff address priority research needs identified by the U.S. Fish and Wildlife Service. On this page, we highlight research taking place in Alaska as part of this program.
Outer Continental Shelf Program
This is a nation-wide collaborative program, supported by the USGS Ecosystems Mission Area, through which USGS and Bureau of Ocean Energy Management staff address priority research needs identified by the Bureau of Ocean Energy Management. On this page, we highlight research taking place in Alaska as part of this program.
Natural Resources Preservation Program
This is a nation-wide collaborative program, supported by the USGS Ecosystems Mission Area, through which USGS and National Park Service staff address priority research needs identified by the National Park Service. On this page, we highlight research taking place in Alaska as part of this program.
Collaborative Science for Priority Information Needs
One of the primary missions of the USGS is to address the science needs of Department of Interior bureaus, particularly those that manage natural resources and lands. This mission is fulfilled through the research and other activities of USGS scientists but also specifically through three USGS nationally-funded programs listed below.
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...
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...
