Water Quality Monitoring Program

Collect water quality information from tributaries to the Huron River to evaluate sources of problems and measure the degree of management success

Supported by:

  • Middle Huron Partners and Stormwater Advisory Group
  • Alliance of Downriver Watersheds – Lower Huron, Ecorse Creek, Combined Downriver
  • Michigan Department of Environmental Quality

What was measured in 2016?

  • 29 volunteers; 319 hours – THANKS!
  • 155 sample sets collected
  • Nutrients (Phosphorus)
  • Sediments (Total Suspended Solids)
  • Bacteria (E. coli)
  • Other (Dissolved Oxygen, pH, Temperature,

Conductivity)

  • 40 flow measures
  • 48 investigative samples
  • 1 storm sample

Other Parameters

  • TSS: High (>80 mg/l) erosion events in Blakely, N. Ecorse, and

Brownstown Creeks in 2016

  • DO: Low (< 5 mg/l) events in Blakely (twice), N. Ecorse (5x), S.

Ecorse (3x), Brownstown (5x), and Silver (5x) Creeks.

  • Temperature: All sites within normal range for warm water

streams (< 29°C / 84°F)

Summary of Results

  • Nutrient runoff high (for P) and not improving. Some erosion

issues.

  • Bacteria high and not improving, except at Woods Creek
  • Runoff from Southland Center and Silver Creek (upstream) in

need of further investigation for source ID

  • Conductivity also high, except for Woods Creek
  • Low DO at 5 creek sites suggests the need for greater

stormwater treatment and restoration. Consistent with insect results?

How does our sampling get used?

Raw sampling data analyzed and reported out

  • Share results and analysis with municipalities
  • Follow up on key findings, actions prioritized
  • Implementation of ideas to address problems
