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...

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...

These data contain counts of fish species collected with a 1.83 m x 9.14 m bag seine constructed of 1.6 mm Delta nylon mesh. When permitted, five consecutive 15.25 m hauls were made parallel to the shoreline. Sites with smaller shorelines were sampled to the greatest extent possible and distance recorded. The seine was pulled in the upstream direction to allow the net to stay open during sampling. Following each haul, fish were sorted by species and counted. Macrophyte community characteristics (percent cover and species) were assessed by visually approximating the proportion of sites occupied by each species. A rake was used to collect vegetation for lab verification of species identification. Other habitat features...
Egg mat retention trials were conducted with walleye (Stizostedion vitreum) and lake whitefish (Coregonus clupeaformis) eggs in an experimental flume tank, seeded directly on egg mats (test retention efficiency) and hand dispersed in flowing flume water to simulate spawning over egg mats (test capture efficiency) with and without alternate substrate. In the field study, we measured number of eggs collected on mats and with bottom drift nets in the Detroit River to compare capture effectiveness. The field collection data describe the number, date of collection, and exact collection location of target species (walleye and lake whitefish). The flume trial data include number of eggs retained or collected, water velocity,...

This data set contains bottom hardness and surficial substrate compositions measured as part of a study evaluating the maturation of fish spawning reef restoration projects in the St. Clair-Detroit River System. 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...
