Aquatic Native Species: Coregonine Restoration

Human activities have greatly impacted fish populations in the Great Lakes, including various Coregonus species such as deepwater cisco (e.g. bloater (Coregonus hoyi) and lake herring (Coregonus. artedi). The USGS, U.S. Fish and Wildlife Service (USFWS), National Park Service (NPS), Bureau of Indian Affairs (BIA), Department of State (DOS) and Great Lakes Fishery...

Aquatic Native Species and Habitat Restoration: Restoring native freshwater fish populations

USGS is working to help restore Atlantic salmon, bloater and cisco populations in Lake Ontario and the St. Lawrence River as part of the Coregonid Restoration effort. These three key species of the native Lake Ontario fish community are extirpated (Atlantic salmon and bloater) or are at low levels of former abundance (cisco).

Areas of Concern: 18 Mile Creek AOC - Fish Community Characterizations

The downstream-most section of Eighteen Mile Creek (also listed as the U.S. Environment Protection Agency (USEPA) superfund site EIGHTEENMILE CREEK LOCKPORT, NY), a tributary to the south shore of Lake Ontario in New York, was designated as an Area of Concern (AOC) because water quality and bed sediments were contaminated by past industrial and municipal discharges, waste disposal, and...

Terrestrial Native Species and Habitat Restoration: Kirtland’s Warbler Cowbird Control

By 1971, 69% of Kirtland’s warbler (a rare songbird with a limited breeding range in southern Ontario and the Upper Peninsula of Michigan) nests were parasitized by Brown-headed Cowbirds (a parasitic brood bird native to the Great Plains), resulting in less than one young Kirtland’s warbler produced per nest. Cowbird trapping began in 1972, and parasitism rates were quickly reduced to around 6...

Asian Carp Integrated Control and Containment: Development of Carbon Dioxide as A Control Tool for Invasive Asian Carp Control

The objective of this project is to develop carbon dioxide (CO2) as a new tool for controlling Asian carp migration. More specifically, navigational structures are potential management pinch-points to block the spread of Asian carps within major rivers throughout the United States. Carbon dioxide has shown promise as a behavioral deterrent for Asian carps and could be a useful non-physical...

Areas of Concern: Coordinated Support and Evaluation of the Maumee AOC

USGS scientists help support habitat assessment and restoration in the Maumee area of concern (AOC) to determine the extent to which beneficial uses are impaired and the types of management actions required to remediate and delist the AOC.

Aquatic Native Species and Habitat Restoration: Quantifying Coregonine Habitat Use Dynamics

Restoring and maintaining extent of native coregonid populations in the Great Lakes is a basin-wide priority. In response, an adaptive framework has identified knowledge gaps associated with spatial dynamics and stock diversity. This project used the Cooperative Science and Monitoring Initiative (CSMI) with an incredible in-kind support from agencies and universities from across the region to...

Areas of Concern: Benthos Toxicity at Wisconsin's AOCs

USGS is assessing sediment toxicity at Wisconsin's Sheboygan River and Milwaukee Estuary areas of concern (AOCs) on Lake Michigan. The study will assess if sediment toxicity from polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), selected metals, ammonia, or low dissolved oxygen is present at either acutely toxic or chronically toxic concentrations. Sediment toxicity...

Areas of Concern: Polycyclic Aromatic Hydrocarbons (PAH) Source Tracking in Milwaukee River

Project objectives are to identify potential Polycyclic Aromatic Hydrocarbons (PAH) sources and quantify PAH loading to the Kinnickinnic River Great Lakes Legacy Act (KKGLLA) Estuary from 2009 through 2014.
