This reflects the system time which determines when inventory becomes available.
One way to determine water quality in a river is by examining the animals that live there. Drop by anytime to spend some time in the Mississippi River catching invertebrates. You’ll learn how to identify what we catch and use a biotic index to find out how healthy our stretch of the river is. Be prepared to wade in the river. A limited number of boots are available to borrow. All ages welcome. Free.
