    Clear Creek, South of E Canyon Rd bridge (downstream) by Erik Nichols

    Reading of 0.0 mg/L listed because the measurement is below the scale on the table. See photograph. Measurement taken about 40 meters downstream of previous measurements, and closer to the opposite side of the creek. This was due to heavy ice cover. Very thick ice has prevented water sampling at this location for two weeks. See picture of melt-hole used for sample.

    Veteran Acres - Sterne Woods (Oakwoods Lodge) by Far Syed

    After it rained, I went out to take a sample, and all the ice melted, which was a nice view of the flowing pond, but it had higher chlorine levels during the 40 degrees weather, but it rained, so the water may got affected due to the rain.

    Harry J. Wolf by Harry Wolf

    Water level at site was high, almost flood stage due to rain the previous night and this morning. Water was turbid. Ground is still frozen so all rain was running off, none soaking into ground. Note that there is also signs of brush clearing upstream of site on right (northeast) bank. Forest Preserve has started this brush clearing project to remove invasive species (Amur Honeysuckle & Buckthorn) along banks and in area.
