We have been monitoring flow and chemistry in Adirondack streams for over twenty years, principally using grab samples and periodic discharge measurements to estimate nutrient loads in support of lake management. We started using remote loggers to measure stream stage in 2007 when we instrumented the tributaries and outlet of Upper Saranac Lake. We expanded our use of remote loggers in 2010 by installing conductivity loggers to monitor stream response to road salting, also within the Saranac River watershed. In 2011 we initiated a new monitoring program called the Adirondack Regional Index Stream Network (ARISN). The purpose of ARISN is to provide high-quality and reliable data in a cost-effective manner that informs science and policy while providing for long-term surveillance for unanticipated change. The ARISN streams were established across a gradient of paved road density and currently include 4 least-impacted streams for benchmarking. Each stream is instrumented with remote loggers for stage and conductivity and is sampled in a manner that allows for high resolution estimates of in-stream nutrient concentrations and export. Our intent is for ARISN to serve as a platform for regional-scale investigations of biogeochemical and ecological responses to stressors in stream environments, and we invite collaborators interested in overlaying their work on this network.
