The U.S. Geological Survey (USGS), New York State Department of Environmental Conservation (NYSDEC), and Cornell University completed a cooperative 2-year study from late 2004 to 2006 to characterize the potential hydrologic, physical, and biological effects of the releases from Lake Abanakee on the Indian, Cedar, and Hudson Rivers in the Adirondack Mountains of New York. Researchers gathered baseline information on hydrology, temperature, habitat, wetlands, and communities of resident fish (brown trout) and macroinvertebrates. Collaborators with the Rochester Institute of Technology measured surface river-water temperatures in August 2005 through remote (aerial) infrared imaging during base and high (release) flows.
