Problem Water temperature is a critical component of trout habitat. Stream temperatures not only affect the distribution, behavior, and survival of trout (and other species), but also compel these species to move toward small areas of preferred temperatures, known as refuges, to maximize growth, survival, and fitness. The Schoharie watershed in the Catskill Mountains, including East Kill, West Kill, and Batavia Kill tributaries as well as the main-stem Schoharie Creek, supports small or transient populations of wild brook trout as well as naturalized and hatchery brown trout. Water temperatures in parts of these rivers typically exceed lethal thresholds for these species for several weeks each summer. Managing agencies...

Background and Problem The Retsof salt mine in the Genesee River valley, Livingston County, New York flooded after roof collapses in 1994 created two rubble chimneys in overlying bedrock that intersected a confined aquifer in the basal glacial-drift deposits (figs. 1 and 2). Groundwater flowed downward through the rubble chimneys causing widespread drawdown in the lower confined aquifer until the mine was completely flooded in 1996 (Yager and others, 2001). By 2005, water levels in the lower confined aquifer had nearly recovered to pre-collapse conditions but the hydraulic connection through the rubble chimneys between the brine-filled mine cavity, saline-water bedrock fracture zones, and the lower confined aquifer...

Background: The New York State Departments of Environmental Conservation (NYS DEC) and Health (NYS DOH) are concerned about groundwater contamination in the carbonate-bedrock aquifers in New York, especially relating to the unintended introduction of volatile organic compounds (VOCs) and liquid manure to these aquifers. These carbonate rocks form extensive aquifers that transmit, and can yield, water from solution-enlarged fractures, bedding planes, and other openings (Olcott, 1995). Groundwater contamination from liquid manure application (fecal coliform bacteria [E. coli] and nitrate) has been on the increase over the past decade as these incidents have been reported to the NYS DEC. Nitrate is highly water-soluble...
