This Benthic Invertebrate Community Analysis dataset, a conceptual subgroup of the Lake Erie Ecological Investigations (LEEI) dataset, focuses on the benthic invertebrates sampled at Areas of Concern (AOCs) on Lake Erie. Per the Quality Assurance Project Plan (QAPP), the invertebrate samples were taken from sediments remaining from the sediment analysis. Identification of the invertebrates was completed by the same invertebrate taxonomist for both the 1998-2000 evaluation and 1986-87 historical evaluation (Smith et al. 1994) for increased consistency. Oligochaetes were identified to species if possible, chironomids were identified to genus, as adult specimens are needed for specific identification, and other taxa...

This dataset is the output of a python script/ArcGIS model that identifes dikes as having a difference in elevation above a certain threshold. If the elevation difference was below a certain threshold the area was not considered a dike; however, if the difference in elevation between two points was significantly high then the area was marked as a dike. Areas continuous with eachother were considered part of the same dike. Post processing occured. Users examined the data output, comparing the proposed dike locations to aerial imagery, flowline data, and the DEM. Dikes that appeared to be false positives were deleted from the data set.
Laboratory bioassays were conducted between 2014-2016 at Wayne State University in cooperation with USGS to determine if different species of cyanobacteria influence quagga mussel spawning and fertilization success. The data describes the algal cultures tested and their density/concentration, the number of individuals tested, and the spawning and fertilization success of quagga mussels exposed to the cyanobacteria and those that were not (control).

A long-term, multiseason, fish egg sampling program is conducted annually on the Detroit, Saint Clair, and Saint Marys rivers to identify where productive fish spawning habitat currently exists. Egg mats were placed on the river bottom during the spring and fall at historic spawning areas, candidate fish spawning habitat restoration sites, and completed spawning habitat restoration sites throughout the rivers. Widespread evidence was found of lithophilic spawning by numerous native fish species, including walleye (Sander vitreus), lake whitefish (Coregonus clupeaformis), lake sturgeon (Acipenser fulvescens), suckers (Catostomidae spp.), and trout-perch (Percopsis omiscomaycus). The data describe the number, density,...

This data set contains water depths and velocities measured with an acoustic Doppler current profiler (ADCP) used to develop a three-dimensional computational fluid dynamics (CFD) model. The CFD model was used to inform fish spawning habitat remediation projects in the Detroit River near Belle Isle. Prior to construction of three fish spawning reefs in 2016, ADCP measurements were made throughout the study area in 2014 and 2016. ADCP surveys were repeated in 2017 following the construction of the reefs. Water velocity measurements made prior to reef construction were used to calibrate the CFD model predicting the flow field over the remediation sites during pre-construction conditions. Following calibration, the...
Well-established conservation planning principles and techniques framed by geodesign were used to assess the restorability of areas that historically supported coastal wetlands along the U.S. shore of the connecting rivers (Detroit River and St. Clair River). The resulting analysis supported planning efforts to identify, prioritize, and track wetland restoration opportunity and investment in the region. To accomplish this, publicly available data, criteria derived from the regional managers and local stakeholders, and geospatial analysis were used to form an ecological model for spatial prioritization.

This dataset contains depths and bottom velocities at discreet sampling locations in the St. Clair-Detroit River System. Measurements were made to complement data on fish egg deposition in the St. Clair-Detroit Rivers from 2005-2016. Depth measurements were made with a boat mounted sonar unit at the beginning of spring and fall sampling season from 2005-2016. Water velocities near the river bed were measured in 2013 and 2015 using a handheld velocity meter attached to a 6.8 kg sounding weight. The sounding weight was lowered off the side of a boat to the river bottom and then lifting the weight slighlty off the bottom to ensure the weight and velocity meter were properly oriented with the current, the mean velocity...

The Lake Erie Ecological Investigations (LEEI) dataset, housed at the Great Lakes Science Center (GLSC) was developed during a reevaluation of Lake Erie Areas of Concern (AOCs) from 1998-2000. These AOCs were recognized as such by the International Joint Commission (IJC) of the United States and Canada due to their severe water pollution problems. The dataset includes data from both the 1998-2000 reevaluation as well as data from other historical evaluations from the 1980’s to mid-1990’s for comparison where available. Data Description: Rivers and harbors of the Great Lakes have been impacted for decades by heavy industrialization, densely populated areas, and agriculture resulting in contamination, eutrophication,...

This represents the flowline network in Connecting River Systems Restoration Assessment (CRSRA). It is attributed with the number of disconnections between the reach and the connecting river system. These data will help identify the condition of hydrologic separation between potential restoration areas and the connecting river system. Low numbers represent fewer disconnections such as culverts between the reach and the rivers requiring no flow network modification to restore the area.

This Fish Community Analysis dataset, a conceptual subgroup of the Lake Erie Ecological Investigations (LEEI) dataset, focuses on the fish communities sampled at Areas of Concern (AOCs) on Lake Erie. Per the Quality Assurance Project Plan (QAPP), fish were sampled for identification and measurement of length and weight. Identification of fish were done by the same biologists for both the 1998-2000 data and the 1986-87 historical data (Smith et al. 1994). Any fish difficult to identify were preserved in buffered formalin for later identification. If large numbers of a particular species were collected the first thirty fish were measured and weighed; remaining fish were individually measured and group weighed. All...

Acoustic telemetry is a popular tool for the study of fish spatial ecology. In acoustic telemetry, fish are captured, surgically implanted with an acoustic transmitter or ‘tag’, and then released back into the environment. Networks of autonomous, stationary receivers then are used to track the movements of tagged individuals over long periods of time (> 1 year). Each acoustic receiver records the date, time, and unique transmitter code (or ID) for each acoustic tag detection. This data set contains detection data for 282 acoustic-tagged lake sturgeon that were captured and released into the Detroit River, St. Clair River, and Lake Huron between 2011 and 2015. Movements of acoustic-tagged individuals were tracked...
