Description of Work This spring (2014) we will measure Asian carp eDNA over time at a Missouri River site downstream of multiple spawning areas before and during spawning. We will measure the amount of Asian carp eDNA in water samples. The amount of eDNA will be related to the numbers of eggs and larvae counted in matched samples (water samples taken at the same time and place). The time since the eDNA was released by the carp will be estimated and these results will be related to the average age of AC eggs and larvae in matched samples. We will also test for substances which interfere with the eDNA measurement techniques and can lead to false negatives. We will also be validating markers developed by USGS and...
Description of Work Since 2010, connecting channels have been included in each of the Great Lakes’ Lake Management Plans (LaMPs). Lake Ontario now includes both the Niagara River and the St. Lawrence River. The Niagara River is well characterized by a number of long-term programs, but because of the lack of tributary water-quality data, the St. Lawrence River and its tributaries constitute a data gap in the information needed for the Lake Ontario to fulfill its goals. Critical information needs, including basic water-quality parameters, total suspended solids, nutrients and flow data. These data are needed to aid in the identification of sources of nutrient and sediment loading to the St. Lawrence. The monitoring...

Description of Work In separate studies, bighead carp and silver carp were raised in waters of varying hardness. Survival, correct development, and hatching success were monitored. Additionally, a search of the Asian literature (including Chinese-language literature) on water hardness in areas where Asian carp are native was performed. Relevance & Impact If soft water limits Asian carp hatching success, then this would mean that large areas of the Great Lakes and east and west coast drainages would not be at risk of Asian carp establishment. Key Findings Both bighead carp and silver carp developed normally and the eggs hatched normally in all water hardnesses tested, including very soft water. The Yangtze River,...

Description of Work U.S. Geological Survey (USGS) is identifying the types and locations of emerging and legacy toxic contaminants in the water and sediments at 59 major tributaries to the Great Lakes (including many Area of Concern sites). This information is needed to help prioritize watersheds for restoration, develop strategies to reduce contaminants, and measure the success of those efforts in meeting restoration goals. The USGS contaminant and virus tributary monitoring network follows the National Monitoring Network for Coastal Waters design. The monitoring effort includes collecting emerging contaminant samples at 17 sites, a subset of the 30 nutrient monitoring sites; and for human viruses and other waterborne...

Description of Work Initial tests of a variety of chemical stimuli identified a strong response to the algal food attractant. Field testing of chemical stimulants based on algae will seek to identify potent mixtures based on persistence and duration of attraction. These studies will include consideration of component chemicals such as amino acids produced by algae that enhance the attractiveness of the stimulus, based on carp smell and taste senses. Means of providing a sustained release of the stimulant will be explored through tests of various media. Tests will be conducted to confirm the possibility that carp can be conditioned to feeding stations that can be used to facilitate their capture. Relevance & Impact...

Description of Work Benthos (benthic invertebrate) and plankton (phytoplankton/zooplankton) communities in Wisconsin's four Lake Michigan Areas of Concern (AOCs; Menominee River, Lower Green Bay and Fox River, Sheboygan River, and Milwaukee Estuary) and six non-AOCs will be quantified. The inclusion of non-AOC sites will allow comparison of AOC sites to relatively-unimpacted or less-impacted control sites with natural physical and chemical characteristics that are as close as possible to that of the AOCs. The community data within and between the AOCs and non-AOCs will be analyzed. This project is a cooperative agreement between the Wisconsin Department of Natural Resources (WDNR) and the US Geological Survey (USGS)....

Description of Work USGS will conduct seasonal sampling of benthic invertebrates, zooplankton, prey fish, and their diets to complement the seasonal lower trophic level sampling by EPA. A point of emphasis is describing the vertical distribution of planktivores and their zooplankton prey, to fill a knowledge gap on these predator/prey interactions. These data will provide a more holistic understanding of how invasive-driven, food-web changes could be altering energy available to sport fishes in the Great Lakes and used to build bioenergetics models that can evaluate whether zooplankton dynamics are being driven by limited resources or excessive predation. Understanding the key drivers of zooplankton will provide...

Description of Work USGS will conduct monthly samples of benthic invertebrates, zooplankton, and water quality as well as seasonal sampling of fish and fish diets. This project supports lower trophic sampling in Lake Erie and understanding food webs. An emphasis will be collecting samples from a nearshore to offshore design.
Description of Work At two of Wisconsin's Areas of Concern (AOCs) on Lake Michigan, the Sheboygan River AOC and Milwaukee Estuary AOC, the USGS will assess whether sediment toxicity from PCBs, PAHs, selected metals, ammonia, or dissolved oxygen is present at acutely toxic or chronically toxic concentrations using sediment toxicity tests conducted with amphipods and midges. Study planning and literature search have been completed. Sediment was collected in October 2016 from sites in the two AOCs and sites in two non-AOC comparison sites. Assesments will be done at two additional sites: Kewaunee River and Oak Creek. Laboratory toxicity tests and chemical analyses are in progress, including sediment toxicity testing...

Description of Work The USGS will communicate these results through coordinating site visits to demonstrate how technologies are applied. USGS will coordinate the communication approach across multiple projects to most efficiently demonstrate technologies and get the information to the stakeholders and managers. A demonstration of Asian carp control technologies occurred in August 2013 near Morris, Illinois at a backwater pond of the Illinois River. State and federal partners were invited to visit an application of the Integrated Pest Management approach to Asian carp control. Water guns, algal feeding attractant, acoustic fish tracking, and commercial fishing were implemented in a coordinated manner to reduce...

Description of Work Jeorse Park Beach is located in East Chicago, Indiana, within the Grand Calumet River Area of Concern (AOC), which has been identified as having all 14 beneficial use designations impaired, including beach closings. Jeorse Park Beach has been identified as one of the most highly contaminated beaches in the nation, with annual beach closings due to bacterial contamination as high as 76% in 2010. Further, beach closings have steadily increased each year since beach monitoring was initiated in 2005 in response to the Beaches Environmental and Coastal Health (BEACH) Act. Beach closings represent an environmental, social, and economic burden, the alleviation of which require various remediation strategies...

Description of Work USEPA Region 5 previously funded a study in 2011 evaluating the toxicity of nitrogen compounds to a select number of pond-dwelling amphibians. The objective of this new study will be to determine the toxicity of nitrogen compounds to stream-dwelling amphibians. Nitrogen contamination in aquatic systems results from the decomposition of organic matter, as well as through agricultural inputs, sewage effluents and industrial activities. Nitrogen in its various forms is of ecological concern because of its ubiquitous distribution and toxicity to aquatic life. Nitrogen compounds pose a hazard to aquatic larval stages of amphibians, affecting survival and development, and inducing deformities and behavioral...

Description of Work Bighead, silver and grass carp larvae were raised in the laboratory. Larvae were observed during the hatching process. Recently hatched larvae were placed in 10 feet tall clear vertical containers where the carp were exposed to light for a similar amount of time during the day as they would experience in a river during the spawning period. Depth selection, swimming behavior, and swimming speed were observed in both day and night periods. Relevance & Impact Understanding the stage at which Asian carps begin swimming is critical to development of models that predict whether a river is adequate for reproduction by Asian carps. Knowledge of where and how Asian carp larvae arrive in nursery areas...

Description of Work In 2014-15 the U.S. Geological Survey and State University of New York at Fredonia characterized the quantity and morphology of floating microplastics in 29 Great Lakes tributaries in 6 states under different hydrologic conditions, wastewater effluent contributions, land uses, and seasons. Tributaries were sampled four times each, during high-flow and low-flow conditions. Samples were collected from the upper 20-30cm of the stream using a 0.33mm mesh neuston net. Microplastic particles were sorted by size, counted, and categorized as fibers/lines, pellets/beads, foams, films, and fragments. References 1. R. C. Thompson et al., Lost at Sea: Where Is All the Plastic? Science. 304, 838 (2004)....

There is an immediate need for effective and safe tools to prevent the spread of planktonic larval dreissenids (quagga Dreissena rostriformis bugensis and zebra mussels D. polymorpha) and to rehabilitate and protect native unionid habitats by controlling existing dreissenid mussel populations in and around the Great Lakes. More than half of the 78 native unionid species in Minnesota, Wisconsin, Iowa, Missouri, Illinois, Indiana, and Ohio are listed as endangered, threatened, or of special concern. Although the US Fish and Wildlife Service (USFWS) considers zebra mussels to be an immediate threat to freshwater unionids in the Upper Mississippi River System, there is no effective tool to control established zebra...
