Summary

BACKGROUND Chemistry data from a group of Adirondack lakes monitored since the mid-1990s indicate that chemical recovery is currently underway and can be attributed to declining deposition loads of sulfate and nitrate in direct response to the 1990 amendment to the Clean Air Act (CAA) and other regulations. Changes in the water quality of several western Adirondack streams suggest that chemical recovery from acidification is underway as well, while data from recent large-scale stream surveys also support the assertion. Changes in stream chemistry, however, appear to be more complicated than changes in lake chemistry. The pH levels in Buck Creek, for example, have changed very little since the 1990s but dissolved organic carbon (DOC) [...]

typeShort Project Description
valueThe USGS is conducting quantitative fish surveys in 36-42 headwater streams (that were surveyed previously), compiling original chemistry records and fish data from the 1979 and 1999 (and 1988-1990) surveys, and generating contemporary (2020-2021) fish species population and community data needed to conduct a future analysis of changes in acid-base chemistry and fish assemblages which may have occurred between the three survey periods and could be attributed to the 1990 amendments to the Clean Air Act.
