Status of American Eel populations in the Mohawk River Basin

Background: The waters of the Mohawk River basin are inhabited by one of the richest fish communities on the East Coast. The American Eel, Anguilla rostrata, is a unique member of this community, exhibiting a catadramous (maturing in fresh water and spawning in salt water) life history. Like many migratory fish, the American Eel has suffered a general decline across the East Coast largely...

Harmful Algal Bloom monitoring in the Finger Lakes region, New York

Background: Harmful algal blooms (HABs) are increasingly a global concern because they pose a threat to human and aquatic ecosystem health and cause economic damages. Cyanobacterial HABs (CyanoHABs) represent a substantial threat to drinking-water supplies, aquatic ecosystem health, and safe recreational uses of freshwater resources in New York. Toxins produced by some species of...

Hydrologic Monitoring in the Central Pine Barrens

The Long Island Central Pine Barrens (CPB) is a large, preserved region of pristine ecological habitat located in eastern parts of Suffolk County, Long Island, NY. The 106,500-acre CPB encompasses portions of the Towns of Brookhaven, Riverhead, and Southampton, and is a core part of the larger Long Island Pine Barrens Maritime Reserve (fig. 1). The CPB overlies portions of Long Island’s...

Responses of fish assemblages to changing environmental conditions in the Neversink River and Rondout Creek

Problem The Neversink River and Rondout Creek are historic trout fishing and recreational streams in the heart of the Catskill Mountains of southeastern NY. Waters throughout upper reaches of both rivers currently range from neutral to severely acidic due to deposition of acid rain throughout their watersheds. Fish surveys conducted by the USGS during the late 1980s and early 1990s found that...

Acidification and Recovery and Development of Critical Loads of Acidity for Stream Ecosystems of the Adirondack Region of New York State

BACKGROUND The Adirondack region of New York has a history of relatively high atmospheric sulfur (S) and nitrogen (N) deposition (Greaver et al. 2012). Adirondack ecosystems have been impacted by these inputs, including soil and surface water acidification, and impaired health and diversity of forest vegetation and aquatic biota. Air quality management, through the Clean Air Act, the U.S....

Adirondack Long-Term Stream and Soil Monitoring

The current Adirondack Long-Term Monitoring Program combines monitoring of streams and soils based on a watershed design. Not only are headwater streams an important component of Adirondack ecosystems, they are closely tied to the terrestrial environment through runoff that is strongly influenced by soil and vegetation processes. This linkage makes headwater streams a useful tool for monitor...

Effects of acid rain on the ecological health of Long Island’s forests and ponds

BACKGROUND Air emissions from the combustion of fossil fuels in electrical power plants, building heating systems and vehicles are the major source of gaseous sulfur (SOx) and nitrogen (NOx) oxides in the atmosphere. These oxides dissolve in atmospheric moisture forming ions which are deposited by rain, snowfall and dust particles as acidic deposition. Acidic deposition releases soluble...

Quantitative Assessment of Water Quality in Upper Esopus Creek: Fish, Macroinvertebrates, Periphyton, Turbidity, and Nutrients

Background The Esopus Creek is located in the Catskill Mountains of New York State and is part of the New York City (NYC) drinking water supply system. 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 a...

National Acid Precipitation Assessment Program Report to Congress 2011: An Integrated Assessment

Title IV has been successful in reducing emissions of SO2 and NOx from power generation to the levels set by Congress. In fact, by 2009, SO2 emissions from power plants were already 3.25 million tons lower than the final 2010 cap level of 8.95 million tons, and NOx emissions were 6.1 million tons less than the projected level in 2000 without the ARP, or more than triple the Title IV NOx em...

Detection and Quantification of Oxygenated Polycyclic Aromatic Hydrocarbons (oxy-PAHs) in Groundwater Near the Former Manufactured Gas Plant in Bay Shore, N.Y.

Introduction As a result of storage and disposal practices at a former Manufactured Gas Plant, or MGP, in Bay Shore, NY, a variety of polycyclic aromatic hydrocarbons (PAHs) have been detected at high concentrations in the surficial, upper glacial aquifer of Long Island. Levels of PAHs initially detected over 10 years ago were in the parts-per-thousand range within a groundwater contaminant...

Assessing Spatiotemporal Patterns in Fish Assemblages from Acid-Sensitive Streams in the Adirondack and Catskill Mountains

Background With few exceptions, the contemporary and past effects of acidification on fish populations and communities in streams across acid-sensitive regions of NY have not been documented. The pervasive lack of information only permits anecdotal insight into the spatial effects of acidification on stream-fish assemblages and essentially precludes any broad effort to quantify temporal tre...
