The Overall Health Index is the average of the six category scores: Economy, Ecosystem, Human Health, Infrastructure, Recreation, and Water. Status of indicators within these categories was evaluated by comparing data to scientifically-derived thresholds or goals.
The Huron River and its watershed are in Monderate Condition
The Huron River and its watershed are in moderate condition (C+). Water quality was in good condition (71%); vast improvements to water quality have been made in this region since the Clean Water Act. The Huron only received a C in Water Temperature (49%) since it can warm to 85 degrees F in the summer, but has low levels of Phosphorus and Nitrogen, leading to good and very good scores. Ecosystem was in moderate condition (59%). The downstream area contains urban areas, but the headwaters region remains relatively undeveloped. While Birds (91%) and the Benthic Community (68%) are healthy, Forests (41%) and Wetlands (56%) scored lower because these land types have been lost over time.
Human Health was in moderate condition (45%). In many places, excess Bacteria (13%) in the water makes it unsafe for body contact, especially after heavy rains. Fish Consumption (24%) is also problematic (see “Forever Chemicals”, left). Infrastructure was in moderate condition (56%). The lowest-scoring infrastructure indicator was Flooding (32%). The Huron does not have Sewer Overflows because of separated sewer and stormwater systems, so this received a very good score.
Recreation was in good condition (74%). The river is popular and well-used by boaters and anglers. The Economy was in moderate condition (45%). The lowest-scoring indicators were Cost of Flooding (18%) and Income Equality (13%), while Household Income received a very good score (86%).
