Winfield Creek

There are two quantab results in the picture for checking standardization of the tabs themselves.

This is the second observation on the same day, in order to make sure the test strips are calibrated

This is the first of two observations on the same day to make sure that the test strips calibrate reliably

The water level is lower than I'd expect at this time of the year.

My Quantab unit measurement was actually 9.0 units. The PPM conversion doesn't go that high up on the card. I looked online and the company said to record it as >628ppm. There were chunks of submerged slushy ice under the top current of water, and two pairs of mallards. I felt like the ducks must have been swimming in brine.
