    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.
