PROBLEM The valley‐fill aquifer in the lower Fall Creek valley (designated as aquifer 4, fig. 1), within the Towns of Dryden and Groton, was mapped by Miller (2000) and identified as one of 17 unconsolidated aquifers in Tompkins County that need to be studied in more detail. The east end of the valley (near the Tompkins and Cortland County border) is on the backside of a large morainal plug, which is part of the Valley Heads Moraine. A large system of springs discharge from the backside of the moraine and forms part of the headwaters to Fall Creek. The valley‐fill aquifer thins and pinches out to the west (figs. 1 and 2)— where the valley is floored by bedrock and becomes a “hanging valley” to Cayuga Lake trough....

Background / Problem – The City of Ithaca, Tompkins County, N.Y., is in the process of developing a flood management plan for the streams that flow through the City. Flooding in the City is caused by a variety of distinct and sometimes interconnected reasons. Flooding often is a result of snowmelt and rain during the winter and spring. Slow ice-melt and breakup can lead to ice jams and subsequent flooding. Flash floods are produced by summer thunderstorms. All of these flood types are compounded by two factors: the storm-sewer system in the City and the elevation of Cayuga Lake. The storm sewers drain to the nearby streams at points below the tops of the streambanks. Because the streamward ends of the storm sewers...

This child item dataset contains a shapefile of labels for hydrogeologic sections illustrated in Heisig, 2023 (figure 3, plate 1). The "Sec_ID" attribute lists letter-number designations for the ends of each section. Hydrogeologic section labels are in the format x - x'. By convention, the x is on the west side and the x' is on the east side of generally horizontal sections. In generally vertical sections, the x is the westernmost of the section ends and the x' is the eastermost end of the section line.

This child item dataset contains a shapefile that delineates ice-margin positions in the Owasco Inlet watershed and surrounding area. Ice positions mostly represent pauses during the final retreat of the ice sheet from the area. Ice-margin positions are delineated by moraines (mostly till) in upland areas and by ice-contact deposits in the valleys.

PROBLEM The unconsolidated aquifer in Enfield Creek Valley (fig. 1) was mapped by Miller (2000) and identified as one of 17 unconsolidated aquifers in Tompkins County that needs to be studied in more detail. Well records in Enfield Creek valley indicate that the northern part of Enfield Creek valley contains sand and gravel deposits which may be under unconfined conditions in some areas, confined in others, or both; and the southern part of the valley contains mostly sand and gravel under unconfined conditions. The valley will probably undergo increased development as the population in Tompkins County increases and spreads out from metropolitan areas. However, there is little geohydrologic data in the valley....

From July to November 2019, 48 environmental samples and four quality assurance and quality control samples were collected throughout the Lake Champlain and Susquehanna River Basins. Samples were collected from 10 production wells and nine domestic wells in the Lake Champlain Basin, and 14 production wells and 15 domestic wells in the Susquehanna River Basin. Of the total wells sampled, 24 were completed in bedrock and 23 were completed in sand and gravel. Approximately 20 percent of samples were collected from wells that previously have been sampled as part of this study in 2005, 2009, and 2014. Groundwater samples were collected prior to any treatment or filtration systems, from existing domestic and production...

This child item dataset contains a shapefile that delineates the overall extent of stratified drift (glacial) aquifers within the Owasco Inlet watershed. The extent includes coarse-grained (sand and gravel) deposits that may be unsaturated, but are contiguous with saturated deposits, and thus may act as aquifer recharge areas.

Problem - The valley-fill deposits in Upper Buttermilk Creek/Danby Creek valleys are sources of water for many homeowners, farms, and small businesses that are in this valley. The aquifer was mapped by Miller (2000) and identified as one of the 17 aquifers in Tompkins County that needs to be studied in more detail. However, there is little geohydrologic data in the valley. A cluster of wells in Upper Buttermilk valley are finished in sand and gravel, indicating that there is a sand and gravel aquifer in, at least, part of the valley. The Upper Buttermilk Creek/Danby Creek valleys are "through valleys"-- a part of a valley where the bedrock floor rose to land surface and formed a preglacial surface-water divide....

From May to December 2017, 48 environmental samples and six quality control samples were collected throughout the Upper Hudson and Central New York River Basins. Samples were collected from nine production wells and 11 domestic wells in the Upper Hudson River Basin, and 14 production wells and 14 domestic wells in the Central New York River Basin. Of the total wells sampled, 22 were completed in bedrock and 26 were completed in sand and gravel. Approximately 20 percent of samples were collected from wells that were previously sampled as in 2007 and 2012. Groundwater samples were collected prior to any treatment or filtration systems, from existing domestic and production wells equipped with permanently installed...

From July 2011 to November 2016, the U.S. Geological Survey, in cooperation with the Town of Newfield and the Tompkins County Planning Department, collected horizontal-to-vertical seismic surveys at 58 locations in the West Branch Cayuga Inlet and Fish Kill valleys to help determine thickness of unconsolidated deposits and depth to bedrock. The HVSR technique, commonly referred to as the passive-seismic method, is used to estimate the thickness of unconsolidated sediments and the depth to bedrock (Lane and others, 2008). The passive-seismic method uses a single, broad-band three-component (two horizontal and one vertical) seismometer to record ambient seismic noise. In areas that have a strong acoustic contrast...

Problem – Flooding is an annual problem along Egypt Creek in Dryden. Increased runoff from expanding development, sediment clogged channels, and undersized culverts that cannot convey increased flows contribute to the problem. Flood maps for extreme floods are available through the effective FEMA flood insurance study (FEMA, 1978), but these maps, which became effective in 1979, are considered no longer valid by the Village of Dryden owing to development in the basin, which presumably has increased runoff and, in at least one instance, encroached on the floodplain. In addition, similar data for lower, intermediate, and higher floods are non-existent. Emergency responders and the public would benefit from a series...

This child item dataset contains a shapefile that delineates traces of hydrogeologic sections illustrated in Heisig, 2023 (figure 3, plate 1). The "Section_id" attribute lists letter-number designations of each section. A second shapefile contains the map labels for the hydrogeologic sections in the format x - x'. By convention, the x is on the west side and the x' is on the east side of generally horizontal sections. In generally vertical sections, the x is the westernmost of the section ends and the x' is the eastermost end of the section line.

PROBLEM The valley-fill aquifers in the West Branch Cayuga Inlet and Fish Kill valleys (designated as aquifer 15, fig.1), within the Town of Newfield, were mapped by Miller (2000) and identified as one of 17 unconsolidated aquifers in Tompkins County that need to be studied in more detail. The valley-fill in the West Branch Cayuga Inlet and Fish Kill valleys contain a heterogeneous mix of glacial deposits and recent alluvium under mostly unconfined conditions, but may they be under confined conditions in some places. The valley-fill deposits are sources of water for the Village of Newfield, homeowners, farms, and small businesses in these valleys. The Village of Newfield has recently been searching for another location...
