Suisun Marsh Salinity Control Gates Log

Metadata Updated: November 23, 2025

This log of operations includes: flashboard installation and removal dates, when tidal operations were started and stopped, and notes any technical issues.

This current document is an Excel file that contains the data as a Table. The Table can be sorted or filtered, and can be read by scripting languages such as Python or R. The date and time are stored together in the DATETIME field. The GATE 1, GATE 2, and GATE 3 fields state whether each gate is operating in Tidal Mode, set to Open, or set to Closed. The ACTION field states what operational change has occurred.

The timestamped records go back to May 5, 2018. If prior dates are needed, refer to the Historical (Archived) Suisun Marsh Salinity Control Gates Log PDF, which contains records going back to November 1, 1998. This document replaces the Archived version because the Archived version did not contain a timestamp for every record. For the records that did have a timestamp, the timestamps were placed in the REMARKS field. This issue, along with the document being a PDF file, created a problem for reading the data into time-series analysis software.
