PROGRAM GOALS

  • Collect high-quality, scientific data
  • n the local waterways.
  • Educate decision-makers and the

public.

  • Provide necessary data for state

stormwater permit reporting.

  • Engage members of the public in

water resources & cultivate local water stewards.

  • Identify impaired areas, provide

evidence for funding improvement projects.

SLIDE 3
  • Meet up in teams of 2-4 individuals.
  • Navigate to sites.
  • Collect water samples.
  • Measure in-stream water chemistry.
  • Record flow measurements.
  • Track water level changes.
  • Identify any areas of concern or illicit

discharges.

  • Deliver samples to lab.

phosphorus TRENDS at Huron River TRIBUTARIES

  • Statistically significant declines in

TP at Mill Creek, Honey Creek, Allens Creek, Traver Creek, and Boyden Creek.

  • No trends at Fleming Creek,

Malletts Creek, Millers Creek, and Swift Run.

  • Storm spikes in urban tribs

counteracting apparent decline in base flow concentrations
