Aging infrastructure is creating a pressing national need to align priorities between civil engineering and other interests. Restoring ecological connectivity of river networks that are fragmented by dams and road crossings has become a prominent objective for environmental managers across the country. A mature decision-support framework and newly available data on the condition of dams throughout the Lake Michigan basin offer unique opportunities to test for potential cost-efficiency gains from sharing the costs of removing decrepit dams between environmental and engineering organizations. At sites where these interests align, genuine win-win scenarios could advance both ecological connectivity and infrastructure...

This dataset provides results of a targeted bacterial community metagenomic analysis of surface water, groundwater, and sand samples at Jeorse Park on Lake Michigan in East Chicago, Indiana. Seventy-two samples were collected from 6 sites in 2017. Samples were analyzed for the 16S ribosomal RNA (16S rRNA) gene (the S in 16S refers to the rate of sedimentation, in Svedberg units, of the RNA molecule in a centrifugal field), and one sample was excluded because it produced too few reads. The 16S rRNA gene is the most conserved of three rRNA genes (16S, 23S, and 5S) and is considered the most reliable for identification and taxonomic classification of bacterial species (Bouchet and others, 2008). Taxonomic analysis...

All gillnet data represented here expand upon vessel operations (OP table) data, all of which are collected by the United States Geological Survey, Great Lakes Science Center and its partners. The Gillnet Tables contain data collected from the research vessel deploying various gear used for gillnet data collection. The database uses sample_type to indicate the gear deployed. The tables relating to Gillnet are: GN_Annulus.csv, GN_Catch.csv, GN_Effort.csv, GN_Fish.csv, GN_L, GN_LF.csv, GN_OP.csv, GN_Prey.csv, GN_Stomach.csv, LMMB_Fish_Prey.csv, and LMMB_Invert_Prey.csv Data Quality: Note that the following data release is a snapshot of the database at the time of release.

The Fox River transports elevated loads of nitrogen and phosphorus to Lake Michigan. The increased concentration of N and P causes eutrophication of the lake, creating hypoxic zones and damaging the lake ecosystem.To decrease loading, best management practices (BMPs) have been implemented in the uplands of the basin. Little work has been done, however, to reduce nutrient concentrations in the river. Rivers are capable of removing nutrients through biotic uptake and sediment burial and are able to remove N through denitrification. Identifying and managing these locations of increased nutrient cycling known as “hot spots” may be another mechanism for nutrient mitigation.Our objective was to identify hot spots of N...

Avian botulism toxicity is a common cause of death to water and shore birds that live near or migrate through Lake Michigan. The botulism neuro-toxin type E (bontE) gene is responsible for the production of botulinum neurotoxin type E. Quantitative Polymerase Chain Reaction (qPCR) was performed using a Step One Plus Thermocycler (Applied Biosystems) and protocol described in Getchell and others, 2011, Journal of Aquatic Animal Health. The assay was used to assess microbial community DNA obtained from environmental samples that were collected by Great Lakes Science Center and by National Park Service from 2011 to 2014 for the bontE gene. Samples were obtained by ponar grab or by divers and matrices collected...

Adult walleye (10 females and 10 males) were caught in Fox River (Wisconsin) during April 2014. Total length, weight, and age were determined for each of the walleye. Whole-fish homogenates were prepared during 2017. Lipid concentration and polychlorinated biphenyl (PCB) congener concentrations were determined in each of the homogenates during 2017-2018. For each sample, PCB congener concentrations were summed to yield total PCB concentration. All lipid and PCB congener terminations were made at the University of Michigan School of Public Health in Ann Arbor, Michigan.

Great Lakes fishery managers and stakeholders have little information regarding how climate change could affect the management of recreationally and commercially important fisheries, which have been valued at more than $7 billion annually. Our research has focused on how climate change could influence fish habitat (including water temperature, ice cover, and water levels), phytoplankton production, and ultimately fish production. Focusing on lakes Michigan and Huron, this webinar provids information about: whether we can detect climate signals in long-term data on fisheries and phytoplankton preliminary climate (e.g., water temperature, ice cover) forecasts for 2043-2065 how future climate could influence growth...

Data were collected as part of a study to identify sources of E. coli contamination at several beaches located in the Grand Calumet River Areas of Concern, located in northern Indiana on Lake Michigan. Water samples were collected at each site (Jeorse Park 1, Jeorse Park 2, Hammond East, Hammond West, Whihala East, and the Grand Calumet River) three times a week for thirteen weeks and analyzed for E. coli bacteria (an indicator bacteria for fecal contamination) and species-specific molecular markers (microbial source tracking, MST), including human (HF183, Mnif), gull (Gull2), and dog (DogBact). Presence of MST markers indicates a fecal source at that location associated with the target animal. Field conditions...

Data included are from a series of field sample collections from Lakes Michigan and Huron, and laboratory mesocosms targeting the round goby fish (Neogobius melanostomus). The round goby is a benthic fish that has heavily invaded four of the five Laurentian Great Lakes. Because it inhabits a variety of substrates, including coastal breakwaters, traditional methods (e.g., trawling, trapping) are inadequate to quantify overall population size. Environmental DNA (eDNA) may be a viable option for improving detection and quantification of the species. Field data include number of round goby caught and associated ambient conditions of the aquatic matrix (temperature, pH, turbidity, conductivity, dissolved oxygen). Mesocosm...

These data were collected as part of the Great Lakes Restoration Initiative (GLRI) project template 678-1 entitled “Evaluate immediate and long-term BMP effectiveness of GLRI restoration efforts at urban beaches on Southern and Western Lake Michigan”. This project is evaluating the effectiveness of projects that are closely associated with restoration of local habitat and contact recreational activities at two GLRI funded sites in Southern Lake Michigan and one non-GLRI site in Western Lake Michigan. Evaluation of GLRI projects will assess whether goals of recipients are on track and identify any developing unforeseen consequences. Including a third, non-GLRI project site in the evaluation allows comparison between...

Groundwater and surface-water samples were collected and analyzed for microbial source tracking markers to identify the primary sources of fecal bacteria at a Lake Michigan beach in Northwestern Indiana.
Data represent lakewide mean chlorophyll-a estimated from SeaWifs and/or MODIS AQUA satellite data. Each daily value represents the mean of all raster cells for the particular day.

Each line in the file “Lake Michigan fish acoustic data from 2011 to 2016.csv” represents the acoustic data and estimated fish density for a single depth layer of water. Surveys are conducted along transects, transects are divided horizontally into successive intervals, and then within an interval there are multiple successive depth layers. Area backscattering (ABC), mean acoustic size (sigma), and fish density are reported for each unique transect-interval – layer from Lake Michigan in the years 2011-2016. Area backscattering (PRC_ABC), mean acoustic size (sigma), and fish density in the intervals and layers of acoustic survey transects of Lake Michigan in the years 2011-2016. The survey is carried out using a...

We surveyed fixed-width transects to determine waterbird distribution and estimate relative density. Transects generally paralleled shorelines to maximize efficiency and safety. Fixed-width transects were spaced at 3.2 and 4.8 km intervals and extended up to 32 km offshore so as to include waters with depth up to 80 m. Transects were established using snapPLAN software (TRACK’AIR Aerial Survey Systems, The Netherlands). Surveys were flown at an average ground speed of about 220 km/h at an altitude of about 61-76 m above the water using a US Fish and Wildlife Service fix-winged aircraft (Partenavia P68 Observer 2). Two trained observers, one on each side of the plane, identified and tallied waterbirds within 200...
