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...

Data are from biological and physical environmental assessments conducted during 2018 in the lower Rouge River, MI. Sites were located upstream, downstream, and within the concrete channel section of the lower Rouge River. Water quality parameters, riparian zone characteristics, reptiles and amphibians, fishes, invertebrates, and river channel characteristics (water depth, flow, velocity) were assessed during 2018 from June-October. Previously established standardized sampling methods were used during all assessments.

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...

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...
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...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
