History
| Rec No. | Date | Loc From | Title | Loc To | Notes |
|---|---|---|---|---|---|
| 6644 | 2024-04-04 | Lab none | Installed | Mayberry Water Level | Installed at MB off of the northeast corner of the scaffolding. Water level data from the HYDROS21 CTD sn H21G200002263 hasn't worked since Feb, but cond/temp seem ok. |
| 6636 | 2024-03-25 | West Pond Water Level | Removed | Lab none | Removed from WP and brought back to the lab. This sensor is needed at Mayberry, so we are slowly decommissioning West Pond. |
| 6364 | 2023-08-08 | Lab none | Installed | West Pond Water Level | Installed at West Pond to replace sn 20010769, which died after 11 years of service. The old sensor is still installed, but not wired to the datalogger. The new sensor is installed temporarily hangingin the water by the staff gauge. We will install a well when the water level drops. |
| 5671 | 2022-02-02 | Gilbert Tract Water Level | Removed | Lab none | Removed from Gilbert Tract as its measurements are now redundant with the HYDROS21 water level sensor. |
| 5515 | 2021-09-02 | Sherman Wetland Water Level | Moved | Gilbert Tract Water Level | Moved from SW to GT with the decomissioning of SW and the beginning of GT. Not installed until 09/09 |
| 5483 | 2020-08-28 | Lab none | Installed | Sherman Wetland Water Level | Installed after repair at Campbell -90cm from top of pipe -45cm from ground surface. |
| 4667 | 2020-08-20 | Factory none | Received | Lab none | Report from CSI: Sensor communicates ok and draws normal current, it does read OOT so it will need a new cal and the rotted 20' cable replaced. Repair: Cleaned up the sensor element, updated OS, calibrated the sensor and had a new 20'cable made. |
| 4658 | 2020-07-17 | Lab none | Shipped | Factory none | Shipped back to Campbell for repair on RMA # 32203 |
| 4657 | 2020-07-09 | Sherman Wetland Water Level | Removed | Lab none | Removed from SW and brought back to the lab because this sensor was causing the met system to short |
| 2930 | 2017-06-23 | Lab none | Installed | Sherman Wetland Water Level | Installed at Sherman Wetland tower |
| 1846 | 2015-05-12 | Sherman Island | Removed | Lab none | Removed with the decommissioning of the Sherman Cow Pasture site. |
| 1071 | 2013-09-05 | Lab none | Installed | Sherman Island | Installed at Sherman Island in newly dig well with perforated PVC tube just south of the computer box. The water pressure sensor is installed 124 cm below the top of the PVC pipe, and the top of the PVC pipe extends 13 cm above the ground surface. At the time of install, the water table was measured at 82 cm below ground and the water pressure reading was 0.43. |
| 880 | 2013-01-03 | Lab none | Installed | DWR Corn | Installed in the original well hole in the corn field. See fieldnotes of details. |
| 879 | 2012-12-18 | Lab none | Repair | Lab none | I pulled apart the existing splice in the cable, cut a small out and made a new splice. After wards I tested it in the lab and it seemed to function well. |
| 858 | 2012-11-29 | Mayberry Water Level | Removed | Lab none | This sensor was removed from the Tule tower due to bad readings. Replaced by brand new CS451 sn20010046 sensor. |
| 817 | 2012-10-25 | Twitchell Rice Water Level | Moved | Mayberry Water Level | Removed from the Twitchell tower since the well was dry and moved to the Mayberry Tule tower to replace the water pressure sensor that failed there. |
| 393 | 2011-07-14 | Twitchell Rice Water Level | Installed | Lab none | Reinstalled in the field after repairs to the cable where otters had chewed on it. I spliced the wires and the tube that provides the atmospheric pressure reference. |
| 394 | 2011-07-07 | Twitchell Rice Water Level | Removed | Lab none | This senor was removed from the Twitchell tower after it was discovered that otters had chewed the cable. |
| 1323 | 2009-05-21 | Lab none | Installed | Twitchell Rice Water Level | Installed at the Twitchell Rice site |
