Background The Upper Esopus Creek, a popular trout-fishing and recreational stream in the heart of the Catskill Mountains, received historic flooding from Tropical Storm Irene on August 28, 2011. Streamflows approached or surpassed the 1% annual exceedance probability (>100 year) flood levels at several USGS streamgages in this basin. Short-term flood impacts on biological assemblages have been assessed in several studies, but longer-term effects, recovery, and analysis of factors affecting ecosystem resiliency have rarely been investigated. The U. S. Geological Survey (USGS), New York City Department of Environmental Protection (NYCDEP), and Cornell Cooperative Extension of Ulster County (CCEUC) collaborated on...

Background Acidification of lotic and lentic environments has been found to adversely affect the integrity of resident biological assemblages. These effects have been particularly severe in poorly buffered regions like the Western Adirondacks. Although the Clean Air Act and its amendments have greatly reduced levels of atmospheric deposition, many streams in this region are still chronically or episodically acidified. In-stream and watershed-wide liming are two directed-mitigation techniques which could be used to accelerate ecosystem recovery and help restore the condition of biological assemblages. The costs and abilities (as well as effective duration) of these techniques to improve water and soil chemistry,...

Background With few exceptions, the contemporary and past effects of acidification on fish populations and communities in streams across acid-sensitive regions of NY have not been documented. The pervasive lack of information only permits anecdotal insight into the spatial effects of acidification on stream-fish assemblages and essentially precludes any broad effort to quantify temporal trends and potential recovery of fish assemblages in less acidic or less toxic streams. Though the effects of acidification on fish assemblages have been qualified in several streams of the eastern Adirondacks during 1979, the 1980s, and early 2000s, (Schofield and Driscoll 1987; Simonin et al. 2005) quantitative impacts were...

Background The New York State Department of Environmental Conservation (NYSDEC) and Adirondack Lakes Survey Corporation (ALSC) repeatedly surveyed fish assemblages and characterized water chemistry from 44 to 52 lakes during the periods 1984-1987 and 1994-2005, and 2008-2012 to document the regional effects of acidic deposition and potential recovery associated with the 1990 Clean Air Act Amendment (CAAA) under the Adirondack Long-Term Monitoring (ATLM) Project. An initial analysis of changes in fish assemblages between the periods 1984-1987 and 1994-2005 noted modest and mixed recoveries, identified five fish-community response/recovery classes, and helped to devise a fish-community index based on species acid...
