I arrive about 2pm with Patty. It was clear, warm and breezy. The wetland looks really brown, but the tules are still largely green. They resurfaced the levees. There is a lot of loose dusty dirt on top that might be a slippery problem if it rains.

The 7500 read: 405ppm CO2, 665mmol/m3 H2O, 100.6SS, 27.0C, 101.23kPa
The 7700 read: 1.96ppm CH4, 43.7RSSI â€“ 68 after cleaning.
There was a ton of cattail fluff stuck to all the open path sensors and spider webs. I clean it all off. I also cleaned the camera window and the radiation sensors.

We installed the miniDOT DO sensors in a profile on the fence post in the channel.

sn 1219 at 66cm below the surface
sn 1221 at 109cm below the surface

There was a bunch of wasps in the wash reservoir box. Did not get a good look, but the water level seemed close to full.

Portable Tower
We took down and brought in the portable tower. Everything was really dusty from the levee resurfacing. We checked the systems before disassembly but left the data for collection in the lab.
The 7700 read: 1.95ppm CH4, 40.1RSSI
The 7500 read: 403.7ppm CO2, 566.6mmol/m3 H2O, 75.1SS, 29.71C, 101.19kPa

The fence posts at both of the portable sites still need to be removed.
