Station comments:

10/03/2024 TOC and Above TOC values from July 1, 2024 to September 28, 2024 are missing due to TOC calculation preparations for the new rating table.
07/01/2024 The reservoir capacity rating curve has been recalculated. Reservoir storage values starting on 7/1/2024 will be calculated using the new rating curve.
01/10/2024 Daily FNF sensor (sensor number 8) was moved to station ID FTO. FTO contains the monthly FNF sensor (sensor number 65).
03/03/2023 Daily PPT INC (incremental precipitation). Rain gage was clogged with debris, total accumulation entered on 2/27/2023 after gage cleared.
08/06/2021 Historic low reservoir storage levels may affect sensors and occasionally result in irregular data. Sensors are recalibrated daily.
08/04/2021 Due to the historic lows reached at Lake Oroville this week, there was an issue with the positioning of the sensors that measure the lake levels which resulted in erroneous data. Daily data for 8/1 and 8/2 has been revised.
04/16/2019 Transmission equipment repaired. Hourly data is back online as of 4/15/2019 10:00.
04/15/2019 Beginning 4/12/2019 16:00, reservoir elevation and storage are not transmitting correctly. Data is being flagged automatically.
12/26/2018 Reservoir elevation and storage reporting correctly starting 12/24/2018 at 10:00.
12/21/2018 Beginning 12/20/2018 14:00 reservoir elevation and storage are not transmitting correctly. Data is being flagged automatically.
02/23/2017 Outflow from Oroville includes all releases from the Oroville Dam (i.e.: Hyatt, spillway, low flow outlet), while River Release (RIV REL) pertains to the Oroville Complex as a whole which includes any releases from the Fish Barrier Dam, Fish Hatchery, and Thermalito Afterbay River Outlet.
12/31/2014 Sensor for reservoir elevation has been repaired. Data from 12/30/14, 0900 is valid.
12/30/2014 Hourly elevation and storage data is invalid since 12/25/2014. Data is being flagged.
