Overview

 What the Kaskaskia Water Quality project was 10

years ago,

 What the 2015-16 project will do, and  What happens after that - opportunities to

implement Best Management Practices.

Methods: analysis

 Flow-weighted calculations  Statistical analyses (one-way ANOVA)  Plotting trends over time (annual means)  Comparison to typical nutrient levels

Other Results

 High P, increasing in

Lower Kaskaskia

 Chemical Oxygen

Demand (COD) 

 Increased turbidity  High fecal coliform

spikes in the 1980’s; then declining

The 2015-2016 Update

 What will the water quality assessment look at this

time?

 How will it be different?

slide-37
SLIDE 37

2014 IEPA 303(d) listed waters

 125 stream sections/lakes listed

…compared with 109 in 2006

slide-38
SLIDE 38

Similarities & differences

 Same subwatersheds  Same methods  14 (or fewer) monitoring stations  1 fewer parameters  Fresh BMP analysis

slide-39
SLIDE 39

Outreach

 Presentations in the upper and lower watersheds  Kaskaskia Watershed Association Summit

presentations

 Other outreach/workshops

After the Study Ends…

 Opportunities for watershed planning,

implementation grants

Groundwork laid to receive state & federal funds! See: Upper Silver Creek and Cahokia Creek, Madison

County  Information towards BMPs

Gets out in front of regulation
