Michael R McHale


I began working for the U.S. Geological Survey in 1997. One of my primary research interests is long-term monitoring and trend analyses. This research involves collecting and analyzing long-term monitoring data to determine the effects of climate and land use change on water quality, water quantity, soil chemistry, and aquatic biology in minimally disturbed watersheds across the United States. As part of this work I chair the Reference Watershed Working Group of the National Water Quality Monitoring Council and administer the National Network of Reference Watersheds. I also conduct watershed research in the Catskill Mountains of New York which is the primary source of drinking water for New York City. My work in the Catskills during the last 2 decades has included the effects of agricultural best management practices on stream water quality, nutrient cycling, and sediment transport.
