20768 30 Jan 2022 @ 1125 --- BenF Thud appeared to be drained while driving by this morning (11:25). It was drained yesterday (1/29) as well around 2:45 pm
20641 03 Jan 2022 @ 1430 03 Jan 2022 @ 1530 BenF Thud appeared to be drained significantly, at LEAST 8 inches below the usual surface of the spring from my best estimate off of what I could see to from the road. It’s worth noting that it was a relatively quick look as I was on snowmobile, however I’m very confident in what I saw as I do a talk on Thud with tours and make an attempt to look at it every day.
