Determination of Sources of Water to the Tully Valley Mudboils

Background and Problem Tully Valley is part of the Onondaga Trough, which extends from the Valley Heads Moraine in the south to Onondaga Lake in the north near Syracuse, New York (fig. 1). The Onondaga Trough is filled with a complex sequence of glacial and post-glacial sediments that overlie Devonian carbonate rock and shale and Silurian shale and salt (fig.2). Mudboils, volcano-like cone...

Lake Ontario Flood Monitoring and Mapping

Problem– Lake Ontario experienced period-of-record (1918-2017) maximum monthly average water levels during May through July 2017. NOAA lake gages recorded instantaneous peaks-of record, 249.2 at Olcott, 249.1 at Rochester, and 249.0 at Oswego and St. Vincent. These high water levels along with wind-generated waves caused flooding of thousands of residences and businesses and the erosion of...

Long Island Topography

The present landforms of Long Island are the result of many geologic processes, some of which began many millions of years ago and some of which began only recently. Most of the major features of the present-day topography, however, are related to the last glaciation, which ended approximately 22,000 years ago.

Long Island Land Use and Land Cover

On Long Island, land use includes the human activities and management practices for which land is used. Land cover is a mosaic of developed, forest, agriculture, and wetlands areas. Both land use and land cover are usually discussed in similar environments. The National Land Cover Database (NLCD) serves as the definitive LANDSAT-based, 30-meter resolution, land cover database for the Nation....

Long Island Water Availability

The foundation of any groundwater analysis, including those analyses whose objective is to propose and evaluate alternative management strategies, is the availability of high-quality data. Some, such as precipitation data, are generally available and relatively easy to obtain at the time of a hydrologic analysis. Other data and information, such as geologic and hydrogeologic maps, can require...

Delineation of the Saltwater-Freshwater Interface at Selected Well Locations in the Town of Riverhead, NY

Problem The Town of Riverhead in the northeastern Suffolk County includes rural farmland and suburbs and is bounded by the Long Island Sound to the north and Peconic Bay to the southeast. Riverhead’s close proximity to saline embayments and its location along the northeastern discharge area for Long Island’s groundwater flow system makes it vulnerable to saltwater intrusion. Several public-...
