Long-term trends in Rainbow Trout growth and naturalized populations in the Ashokan Basin

Background: Rainbow Trout (Oncorhynchus mykiss) have thrived in the Esopus Creek since their introduction in the 1880s. The construction of the Ashokan Reservoir in 1915 changed the fishery by providing a stable lentic environment where adult trout could grow large and find refuge during periods when stream conditions become stressful. Although many adult Rainbow Trout spend time in the...

Development of Long Island Water Quality Integrated Data System (LIQWIDS) - User interface and web services in support of collaboration under the Long Island Nitrogen Action Plan(LINAP)

PROBLEM There are more than 60 organizations and agencies collecting water-quality data on Long Island. The types of database management that are used to store and archive regulatory and non-regulatory data vary from paper forms to spreadsheets to State and Federal databases, and there is minimal communication between these systems. As a result, those interested in analyzing data may be...

Nutrient Loads from the Upper Connecticut River Watershed

River-borne nutrients, especially nitrogen, contribute to water-quality degradation in Long Island Sound. The Connecticut River is the largest tributary to the Sound, and quantification of nutrient loads from the three upper States in the watershed, as well as the State of Connecticut, is essential for prioritizing efforts to improve the Sound’s water quality.
