Daily Station Water Level in the Sacramento-San Joaquin Delta, 1915-2023

The dataset contains daily maximum and minimum water at twenty-five sites within the Sacramento-San Joaquin Delta, including newly-digitized data spanning the years 1915-1982. Quality assurance procedures and datum corrections were applied to provide time series referenced to a common geocentric datum. Data-rescue and digitization efforts extend available records by several decades, and thus facilitate analysis of multiple interconnected processes in the Delta, including sea level rise, subsidence, tides, flood hazards, climate patterns, shoreline/habitat changes, bathymetric modifications, and water resources management. Version 2 presents data in an updated format displaying year, month, day, hour, minutes, corresponding daily maximum water level, data completeness, and year, month, day, hour, minutes, corresponding daily minimum water level, data completeness. Additional errors in newly digitized data were also corrected.
