Flood-Inundation Maps for the West Branch Delaware River, Delhi, New York

Delhi has experienced severe flooding along the West Branch Delaware River (fig. 1); most notably during January, 1996, June, 2006, and October, 2010, and August, 2011. Emergency responders would benefit from a library of flood-inundation maps that are referenced to the stages recorded at the USGS streamgage upstream from Delhi. By referring to the appropriate map, emergency responders could...

Southeastern New York Tide-Telemetry and Coastal-Flood-Warning System

The coastal areas of southeastern New York (fig. 1) are highly vulnerable to tidal flooding (fig. 2). Timely evacuation of people from flood-threatened areas in advance of approaching hurricanes and nor'easters (northeast coastal storms) requires adequate flood-warning time. To begin addressing this need for immediate information on coastal flooding, the U.S. Geological Survey (USGS), in...

Spatiotemporal trends in fish assemblages of the Mohawk River

Problem The mainstem of the Mohawk River extends from Lake Delta Dam near Rome, NY downstream to its confluence with the Hudson River near Cohoes, NY. It supports a diverse fishery that is used extensively by recreational anglers. Smallmouth bass (Micropterus dolomieu) and walleye (Sander vitreus) are among the most popular game species with anglers but past biological surveys have...

An Integrated Assessment of the Recovery of Surface Waters from Reduced Levels of Acid Precipitation in the Catskill and Adirondack Regions, New York

Problem - Acidic precipitation has affected forested and aquatic ecosystems in New York, particularly in the Adirondack and Catskill regions. Acidification of surface waters and deleterious effects on fish and other biota have been well documented in both these regions. Despite reduced levels of acidity in atmospheric deposition over the past 20 years across New York and the northeastern Uni...

An Assessment of Forest Health and Soil Nutrient Status to Determine the Effects of Logging Practices on Water Quality in New York City's West-of-Hudson Watersheds

The growth of temperate forests is typically limited by the availability of nitrogen. Elevated concentrations of nitrate in some Catskill Mountain streams, which are tributary to New York City's water-supply reservoirs west of the Hudson River, indicate that the forests of this region are at the early stages of nitrogen saturation. That is, nitrogen is available in excess of the amount utili...

Assessment of Regional Forest Health and Stream and Soil Chemistry Using a Mulit-Scale Approach and New Methods of Remote Sensing Interpretation in the Catskill Mountains of New York

The overall goal of this project has been the development of forest health and sensitivity indicators and “1st-generation” maps of potential sensitivity to disturbance for lands within watersheds of the NYC water supply in the Catskill Mountains of New York. The methodologies and data layers created in this effort can now be used to aid management decisions and help determine the extent and...
