Outline
• Background and methods
• Impairments and Monitoring Results (~12 slides for each model basin)
• Kewaunee Model Basin• Manitowoc Model Basin• Sheboygan Model Basin
Why do we need monitoring for TMDL development?
• Calibrate watershed model
• Further identification of impairments
• Nitrogen not use for calibrating the watershed model
Model inputs:
Uncalibrated model outputs:
- Stream flow- TP & TSS loads
Calibrated model outputs:
- Stream flow- TP & TSS loads
Monitoring Summary
39 Chemistry sites
22 Flow Sites• 19 DNR • 3 USGS
21 Load Sites
Monitoring efforts identified a significant number of impaired waters for the draft 2020 list
