Water Depths and Velocities at Fish Egg Sampling Sites in the St. Clair-Detroit River System, 2005-2016

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 over a 40 second interval was then recorded. This is a companion dataset to the Fish eggs collected in the St. Clair and Detroit rivers, 2005-2016 data. Depth measurements were made at the beginning of each sampling season and water velocities were measured in 2013 and 2015 to complement data on fish egg deposition in the St. Clair-Detroit Rivers from 2005-2016.
