Water quality of lakes in Voyageurs National Park, Northern Minnesota, 1999
Payne GA and US Geological Survey. 2000. Water quality of lakes in Voyageurs National Park, Northern Minnesota, 1999. U.S. Geological Survey (USGS) Water Resources Investigations Report. 00-4281. Mounds View, MN
Water-quality samples were collected during July 1999 from selected lakes and bays, and the mouths of two rivers that flow into Voyageurs National Park in northern Minnesota. Results of laboratory analyses and field measurements of chemical and physical properties were compared to similar data collected during 1977–83. Water-quality data were evaluated for changes in specific conductance, alkalinity, nutrients, trace metals, bacteria, and trophic state. Specific conductance and alkalinity were similar to the 1977–83 period in much of the Park, but in some lakes and bays.
