St. Clair River Shoreline Remediation Evaluation Site And Sample Data 2015-2016 This data set consists of counts and lengths of fish collected as part of a 2015-2016 evaluation of shoreline remediation projects in the St. Clair River, Michigan, USA. Remediation sites were sites that had undergone shoreline softening to convert vertical seawalls to sloping banks, reduce water depths, create a gradual transition between shoreline to main channel habitats, and provide structure (e.g., root wads and boulders) for fishes and other aquatic biota. Control sites were other wade-able (less than 1 meter) areas along the St. Clair River where shoreline softening projects had not taken place. Control sites included public beaches and access points to the St. Clair River and generally had limited in-stream...

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... Categories: Data; Tags: Anthropogenic Rock Reef Substrate, Aquatic Biology, Belle Isle, Detroit River, Geomorphology, All tags...

Five spawning reef complexes (Middle Channel, Harts Light, Pointe Aux Chenes, Grassy Island, and Belle Isle) constructed with 10-20 cm broken limestone from 2012-2016 were evaluated as part of the study. Sonar surveys began in 2012, following the construction of the Middle Channel Reef complex and expanded to additional projects, as they were completed (Harts Light and Pointe Aux Chenes Reefs in 2014, Grassy Island Reef in 2015, and the Belle Isle Reef complex in 2016). Sonar surveys over the Fighting Island... Categories: Data; Tags: Anthropogenic Rock Reef Substrate, Aquatic Biology, Artificial Reef, Belle Isle, Detroit River, All tags...
