Digging into the soil of wetlands
Scientists at the U.S. Geological Survey Wetland and Aquatic Research Center (www.usgs.gov/warc) study important aspects of wetlands, such as the flow and quality of water, the chemistry of soil, and the plants and animals which call this ecosystem home.

Eel airlift bypass prototype
Prototype design of an airlift developed at CAFL to transport downstream migrant eels through a bypass pipe and away from turbine intakes. The airlift design passes eels as well as a conventional siphon or gravity pipe.
