Notes

No unusual smells or colors; no animals; tourists on the Swinging Bridge; current > 1 ft/sec; no wind. Rain in last 24 hours with large discharges from upstream reservoir, though water level was only about one foot higher than 11-03-18 observations and the upstream gage was steady. Water was clear to a foot or two. Adequate depth.
N.B.: Coliform results should be reported as 600 and 9200 to be correct wrt number of significant figures, but I have opted to go with the AWW convention.
