Integration of multiple methodologies as an indicator of cyanotoxin occurrence in Owasco Lake, New York Integration of multiple methodologies as an indicator of cyanotoxin occurrence in Owasco Lake, New York
Cyanobacteria harmful algal blooms (cyanoHABs) pose environmental and public health risks in lakes with highly variable cyanobacteria and cyanotoxin distributions. We compared results from 3 independent monitoring programs to characterize spatiotemporal patterns in the stratified, mesotrophic Owasco Lake, one of the Finger Lakes in New York. Biweekly open-water samples collected at...
A spatial analysis of the groundwater emergence flood hazard in Long Island, New York, and coastal areas surrounding Long Island Sound in New York, Connecticut, and Rhode Island A spatial analysis of the groundwater emergence flood hazard in Long Island, New York, and coastal areas surrounding Long Island Sound in New York, Connecticut, and Rhode Island
Long Island, New York, and nearby coastal areas surrounding Long Island Sound are densely populated and, like other coastal areas, are susceptible to flooding from several potential sources, including stormwater from precipitation events, tidal flooding and storm surge, and groundwater emergence flooding. Groundwater emergence fooding refers to the intersection of a rising water table...
Hydrogeology and water quality of the unconsolidated aquifer system in the lower Fall Creek valley, Tompkins County, New York Hydrogeology and water quality of the unconsolidated aquifer system in the lower Fall Creek valley, Tompkins County, New York
The U.S. Geological Survey, in cooperation with Tompkins County and the Town of Dryden, conducted a hydrogeologic investigation of the lower Fall Creek unconsolidated aquifer system in Tompkins County, New York. This study is part of an ongoing effort to characterize major valley-fill aquifers in the region to support sustainable groundwater management. The lower Fall Creek valley...

Lake Champlain Basin Research
The USGS works in collaboration with Federal, tribal, state, university, Canadian Provincial, and non-government organizations on research and monitoring efforts in the Lake Champlain Basin. For many years, the USGS has produced water quality, hydrologic, and ecological data and science to support the management of the lake and watershed through increased scientific understanding.
