An Adaptive Management Approach to Assessing Water as a Critical Habitat Need for Lesser Prairie-Chicken Reproduction Man-made water sources have been used as a management tool for wildlife, especially in arid regions, but the value of these water sources for wildlife populations is not well understood. In particular, the value of water as a conservation tool for Lesser Prairie-Chickens (Tympanuchus pallidicinctus) is unknown. However, this is a relevant issue due to a heightened conservation concern for the species and its occupancy of an arid landscape anticipated to experience warmer, drier springs and winters. We assessed if Lesser Prairie-Chickens would use commercially available wildlife water guzzlers and if there was any apparent selection between two design types. We confirmed that Lesser Prairie-Chickens would use bird...

These tunnels can intersect faults and fractures that produce large amounts of ground water. For example, one tunnel excavation intersected fractures that produced over 200 gallons per minute of ground-water flow into the tunnel. Consequently, there is a need to determine the potential of intersecting ground-water producing fractures during tunnel excavation. The use of advanced borehole geophysical techniques by the USGS during tunnel excavations in northern Queens County demonstrated that geophysical techniques can...

Onondaga County Soil and Water Conservation District (SWCD) has promoted best-management practices to decrease loads of nutrients and sediment from agricultural lands. Onondaga County Department of Water Environment Protection has abated many of the outflows from combined sanitary-and-storm sewers in the city of Syracuse and has upgraded treatment capabilities for removal of nutrients in effluent from the county's Metropolitan waste-water-treatment plant. These measures have fallen short of target levels of phosphorus and nitrogen loadings to Onondaga Lake because of inputs from nonpoint sources of pollution....

Better information on fish distribution is needed for habitat assessment and modeling activities and is also important for planning industrial activities. The State of Alaska maintains a fish distribution database for anadromous fish species, however there is currently no analog for resident fish species. The concept behind AquaBase was to fill the information gap for resident fish by design a database that contains information about all fish species. AquaBase does not duplicate information that is already available in other spatial database, but rather ‘rescues’ data from reports that are not readily available.

The nutrients stimulate excessive algal growth and potentially cause noxious blooms and hypoxia. Sediment increases turbidity near stream mouths and, when deposited, can smother bottom-dwelling animals, drive fish from affected areas, and decrease water depth in navigation channels. An understanding of the hydrologic and water-quality processes that generate these loads will assist water-resources managers in making informed decisions regarding prevention or mitigation of these problems.

An outlet control structure at the south end of the lake controls surface water outflow and protects adjacent property within the floodplain of Moreau Lake. The lake is considered a kettle lake and as such is surrounded by ice-contact sand and gravel (NY State Parks, 2006).

The basin was dammed in 1915 to form the Ashokan Reservoir splitting the creek into Upper (upstream of the reservoir) and Lower segments. The drainage area of Upper Esopus Creek, between the source (Winisook Lake) and the Ashokan Reservoir is approximately 192 mi2. The Schoharie Reservoir, located 27 miles north of the Ashokan Reservoir, also supplies water to Upper Esopus Creek (and to the Ashokan Reservoir) via the Shandaken tunnel. Waters from the Schoharie watershed enter Upper Esopus Creek at the Shandaken portal and travel 18 km before entering the Ashokan...

Wastewater from the numerous homes and businesses in the barrier island communities generally is discharged directly into the shallow ground-water system through use of private septic systems. Contaminants entering the ground-water system can pose a threat to coastal habitats, as they are transported by ground water that discharges to ocean and estuary shorelines. In October 2004,...

In the absence of chemical loading rates that were specific to the Onondaga Lake Basin, the model was calibrated to estimated loading rates that were derived from a review of scientific literature.

The open landscape character of longleaf pine ecosystems is characterized by a lower carbon stocking and prairie-like understory dominated by grasses and low woody vegetation . Lower carbon stocking combined with greater drought tolerance in longleaf pine suggest that longleaf pine stands generally consume less water relative to loblolly pine and slash pine dominated stands.

Recent hydrogeologic mapping in Manhasset Neck indicates significant glacial erosion of the Magothy aquifer, Raritan Clay, and Lloyd aquifer, and several gaps in the confining units that overlie the North Shore and Lloyd aquifers.

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...
