Wednesday, March 30th Stream Observations

Conditions:
Date: 03/30/2016

Time: 1:02 PM

Weather: Clear skies, sunny, and windy, 57°F

Observations:

Stream Conditions: Low turbidity, very small bubbles, calm

Stage behind Weir: Reading = 12 cm; Actual = 33 cm

Observations: The plastic bag was still in same place from Monday.  There were also a lot of algae on the rocks and stick in the stream.  Although the flow varies slightly, there was no precipitation during the 29th or 30th.  At around 12 PM, flow starts to dip from 4 cfs to 3 cfs at around 3 PM.  The flow then rises back up to 4 cfs by 9 PM.  This decrease in flow could be due to a temporary obstruction or abstraction upstream.

Analysis:
Estimated flow rate from weir data: 5.52 cfs
