Others: Joe, Sara

Summary: Swapped 7500 head, cleaned DO probe, normal data collection

We arrived at 1:15pm. Sunny with no wind. Brian stopped by for a chat. I collected data, Joe cleaned the sensors and swapped the 7500 head (replaced sn 0065 with sn 75H-2150 — now we have the correct head with the correct box). Sara checked the rain gauge—looked good. Sara also cleaned the DO probe and made sure it was submerged and filled the reservoir—it was ~1/5full.
