Summary: Recent rain, young unsupervised cows broke the fences, Tower top HMP45 fan dead and replaced, new cable and mount for IRT CR1000 radio link, lowered Road well sensor, desiccant for z-cams

I arrived at 10:40. It was clear sunny and cool with a west breeze rising. There was rain the day before and the ground is wet but still hard. Some larger puddles on the road but no noticeable change in the pond. The trees are completely bare the rain having knocked off the last of the leaves. The grass is still poking along but is being held in check by the cold nights now. Itâ€™s very patchy but most 1-2cm in height.

The mama cows have been removed leaving a bunch of young hoodlums that broke all the fences. I repaired the fence wires and turned on the electrical chargers since the fire danger has reduced.

I collected the data, did the well, soil moisture and DBH measurements.

The HMP fan at the top of the tower was dead. I took the shield apart, cleaned it and the HMP45, replaced the fan and put it back together.

The radio link to the IRT CR1000 was down again. I replaced the antenna wire with a longer one and move the antenna to a new mount farther away from the metal structure of the tower and metal data logger box. We will see if that fixes it or not. The woodpeckers had stuffed this box full of acorns.

The z-cams all had some condensation on the inside of their windows. I added desiccant packs to the boxes. Z-cam1 images were pretty much all bad due to the condensation â€“ but no leaves on the tress right now.

The road well sensor has been high and dry for a while. I removed its data logger box from the post and put in the ground next to the well pipe. This freed up a couple feet of cable and lower the sensor which read 1.682ft. I might need to bolt the box to the concrete pad to keep it from getting kicked around by the cows. And I donâ€™t know the exact distance the sensor was lowered â€“ need some more manual water level measurements.

I collected the FD chamber data can cleared their memories.

I left at 15:00

A pine fell some time ago near OSU SP3. Its roots were pulled loose right around some oaks.
