One of the longest running programs we have at the Urban Ecology Center is called River Connections. Through this program, students get right into the Milwaukee River in hip waders to test water quality at two locations – one urban, here in Riverside Park, and one rural, at Riveredge Nature Center. The students are amazed when, on occasion, the readings they find in the city are better than the rural readings. We teach them that this is due, in part, to the removal of the North Avenue Dam which allowed the river to flow free, cleaning itself. This free flowing water is essential to river health, which is essential to our health.
