Summary: Quick site check – all ok, water levels lower, lowered DO probe.
| East End 2014-05-21 I arrived about 12:00 with Joe, Madeleine, and Dennis. Dennis met us at Twitchell Island after his meeting in Sacramento. It was clear, sunny and warm with a nice breeze from the west. Water levels were about 30 cm lower than previous weeks. The DO probe was nearly out of the water so I lowered it so that it was about 10 cm below the water surface. A boom of about 4" PVC pipe has been installed all along the levee in places where the erosion has been worst. The 7500 read: 15.20 mmol/m3 CO2, 560 mmol/m3 H2O, 101.40 kPa, 24.7 C, 248 diag The 7700 read: 1.92 ppm CH4, 21.49 RSSI -> 88.0 after cleaning. I topped off the 7700 reservoir. Joe checked the tower. All ok. |
