Due to a loss of data between 06/18/2024 and 06/24/2024, possibly due to lightning striking the station, the salinity moving average between 06/25/2024 and 07/07/2024 is based on less than the standard 14 days of data. Data between 03/11/2024 and 07/21/2024 are provisional. The Little Lake gage is the primary gage used to guide diversion operations from June through November.
