David S Armstrong
Dave Armstrong is a Hydrologist in the New England Water Science Center.
Dave has more than 25 years of experience investigating water resource issues in New England. His background is primarily in surface-water hydrology. He completed his B.A. in Geosciences at Hobart College in 1982, and took graduate courses in forest hydrology, ground-water hydrology, and limnology at the University of Minnesota.
Dave has extensive experience working on multidisciplinary investigations to support state water-resource managers in their efforts to protect and restore water resources, habitat, and ecosystems in New England. He is author on numerous USGS technical reports with a focus on understanding relations between streamflow and habitat; and ecological responses to water withdrawals and land-use in streams and wetlands. Dave currently is working on investigations that are developing a water-quality monitoring strategy for the Taunton River Estuary and Mount Hope Bay, collecting water-quality data at freshwater sites in eastern Massachusetts to demonstrate a process for calculating aluminum criteria, and investigating fish and macroinvertebrate responses to impervious cover.
Science and Products
Development of a Water Quality Monitoring Strategy for Mount Hope Bay and the Taunton River Estuary, Massachusetts
The U.S. Geological Survey (USGS) and Massachusetts Department of Environmental Protection (MassDEP) are collaborating on a study to develop a water quality monitoring strategy for Mount Hope Bay and the Taunton River Estuary.
Water Quality Data Collection to Support Aluminum Criteria Development in Massachusetts
The U.S. Geological Survey (USGS) and Massachusetts Department of Environmental Protection (MassDEP) are collaborating on a study to collect water-quality data at streams and ponds in Massachusetts that receive aluminum discharges from wastewater treatment (WWTF) or public-water supply (PWS) facilities. The objective of this study is to inform the development of MassDEP guidelines on discharge...
NorEaST: A Tool to Understand the Responses of Fish to Changes in Stream Temperature
Climate change is expected to alter stream temperature and flow regimes over the coming decades, and in turn influence distributions of aquatic species in those freshwater ecosystems. To better anticipate these changes, there is a need to compile both short- and long-term stream temperature data for managers to gain an understanding of baseline conditions, historic trends, and future...
