Four low order Adirondack streams were investigated from September 1988 through June 1990 to examine the effects of hydrologic events in relation to stream chemistry and associated biological communities. The four streams were monitored continuously for pH, specific conductivity, temperatures, flow and water quality using a variety of instrumentation and procedures. During base flow and hydrologic events, weekly water samples were collected manually. Assessment of the biological communities in response to changes in water chemistry involved a number of standard fisheries techniques including electroshocking for population estimates, in situ bioassay experiments and radio tagging experiments.
