    Harry J. Wolf by Harry Wolf

    Recent weather has been cold with snow on Wednesday (2-12) and again on Friday (2-14). Local streets were heavily salted due to snow storms and cold. Site was monitored because of short warm up, I thought there might be more runoff. Also note that riparian areas around site are being clear-cut of invasive species resulting in bare banks and area.

    Bourbonnais Creek Upstream by ONU Earth & Space Sciences River Keepers

    Measurement is actually 6852+ ppm Cl-, but the field doesn't allow or a higher measurement than 5000 ppm Cl-. This value was duplicated for verification purposes. Another reading earlier at 4:00 PM read 9.2, which maxed out even the high-value Quantab strip's conversion chart. Photos attached. LOTS of salt added to roads for this storm.
