Notes

No unusual smells or colors; no animals; no tourists on the Swinging Bridge; dog that lives adjacent to west parking area seen in parking area; current > 3 ft/sec in mid stream of river; no wind. Current in collection area swirling and evident but < 1 ft/sec. Sky cloudy to partly cloudy. No rain in last 24 hours but with large discharges from upstream reservoir due to heavy watershed wide rains two days earlier; water level 10 - 15 ft higher than 12-01-18 observations, and the upstream gage was steady-to-slow-rise. Water was clear to a half to one foot. Adequate depth.
N.B.: Coliform results should be reported as 4100 and 17800 to be correct wrt number of significant figures, but I have opted to go with the AWW convention.
