Acoustic Doppler Current profiler (ADCP) field measurements of flow velocity and discharge from the Middle Channel of the St. Clair River delta, Michigan, collected May 2-4, 2022 Field measurements of flow velocity and discharge were acquired from the Middle Channel of the St. Clair River delta, Michigan, May 2-4, 2022. The velocity and discharge measurements included in this data release were obtained using a SonTek M9 acoustic Doppler current profiler (ADCP) deployed from a boat with an outboard motor. River Surveyor Live software version 4.1. was used to acquire and store the ADCP files. The ADCP data were collected along 8 transects spanning the width of the Middle Channel; two passes across the channel were made at each transect. This data release provides text files derived from the raw ADCP data files using the Velocity Mapping Toolbox (VMT) software version 4.09. Text files with...

A multibeam echosounder was used from the Great Lakes Science Center research vessel Cisco to collect the hydrographic data. These data were used to generate maps of river bottom topography in locations where spawning substrates have been placed. The reefs surveyed in the Detroit River included: Fort Wayne, New (East) Belle Isle, Belle Isle, and Grassy Island. The reefs surveyed in the St. Clair River in 2021 included: Middle Channel, Pointe Aux Chenes, and Harts Light. The data for each study reach were produced in LAS format supported...

A multibeam echosounder was used from the Great Lakes Science Center research vessel Desmid in to collect the hydrographic data. These data were used to generate maps of river bottom topography in locations where spawning substrates have been placed.

This work was conducted as part of a reimbursable agreement with the Environmental Protection Agency to provide technical assistance in areas of concern. A multibeam echosounder was used from the Great Lakes Science Center research vessel Cisco in 2021 and Desmid in 2022 to collect the hydrographic data. These data were used to generate maps of river bottom topography in locations where spawning substrates have been placed.

Three sediment samples were collected upstream of the artificial spawning reefs constructed in the Middle Channel and two on the reefs themselves.The bed sediment samples were dried and sieved at 1/2 phi increments to determine their grain-size distribution.
