Twitchell Rice

We arrived about 10:15 PDT. It was overcast, cool, and windy. The weeds appear to be dying as a result of the herbicide applied 2 weeks ago. The water level was high.

Sara did veg height and reinstalled TC profile #2 while I attended to the tower, downloaded data, and applied glue to the camera window plate.
