Summary

Background Forested watersheds in the southwestern Adirondack Mountains of New York received some of the most acidic deposition in North America from the 1970s through much of the 1990s (NADP 2005). Thus it is not surprising that associated effects on surface-water quality and ecosystems in lakes and streams of the southwestern Adirondack Mountains of New York were investigated to various extents over the past 35 years; first to document acidification effects and then to evaluate potential recovery. In fact, evidence of adverse impacts on water quality and aquatic ecosystems across the region provided much support for implementation of the Clean Air Act (CAA) of 1990. Although the underlying effect mechanisms were not well understood, [...]

typeShort Project Description
valueUSGS plans to determine how the Clean Air Act and climate factors may have interacted to alter watershed and stream geochemistry (increased DOC and pH and decreased Alim concentrations in surface waters) beyond a threshold that may permit native brook trout to survive for extended periods in formerly acidified streams in the southwestern Adirondacks.
