Problem - There is a stated need to provide information on loading of persistent toxic pollutants to Lake Ontario from New York tributaries. The information is specifically required for the Lake Ontario Mass Balance Model, which is an integral part of the long-term Great Lakes research. The project described here is designed to demonstrate a cost-effective approach for estimation of loads of polychlorinated-biphenyls (PCBs) through use of a relatively small number of large-volume whole-water samples for PCB analysis. The Black River basin was selected to demonstrate the feasibility of the approach because it is the largest New York contributor of PCBs to Lake Ontario. Objectives - The objective of this project...

Problem - Urbanization of the 150-square-mile Irondequoit Creek basin in Monroe and Ontario Counties, N.Y., continues to spread southward and eastward from the City of Rochester. Conversion of forested land to other uses over the past 40 years has increased to the extent that more than 50 percent of the basin is now developed. This expansion has increased flooding and impaired stream-water quality in the northern (downstream) half of the basin. A precipitation-runoff model of the Irondequoit Creek basin could be used as a management tool by water-resources managers to better understand the hydrology of the basin, permit simulation of planned or hypothetical land-use changes, evaluate the adverse effects of future...

Problem - During 2003-07, a precipitation-runoff watershed model with water-quality components was developed to assess pollutant sources and loadings to Onondaga Lake, and to assist water-resources managers in making decisions regarding the selection and location of mitigative measures to maximize load reduction for a given effort. 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. During 2005-08, an intensive water-quality study of the basin was conducted to provide basin-specific data that, among other uses, could be incorporated into the watershed model and provide...

Objective: The USGS New York Water Science Center (NYWSC) works with other Federal agencies as well as with State, municipal, and tribal agencies to provide research and data about water-related issues. Relevance and Impact: The NYWSC leads the scientific and water-resources management communities by providing high-quality, timely, and unbiased scientific data, reports, and other information that are widely accessible and understandable and that benefit science interests of all levels of government, academia, nongovernmental organizations, the private sector, and the general public. Statement of Problem: The NYWSC studies the effects of weather, climate, and manmade influences on groundwater levels, streamflow (discharge),...

Problem Nutrients and sediment are generated by and removed from agricultural and urban areas, transported in streams, and ultimately delivered to the Great Lakes. 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. A precipitation-runoff watershed model is a tool, which can...
