The fall water quality tests were taken on the first misty day following a month of sunny, dry weather. Water flow was at a minimum.

The spring water quality tests were taken about 5 days into a dry spell. The high water mark was still evident (damp ground), but the water level on this particular day was approximately the same as that during the fall sampling day.
