WATER-LEVEL MEASUREMENTS: Water levels are measured manually by means of a calibrated electric tape. Electric tape is used to avoid entangling the sensor and cable. Correction factors (comparison to a steel tape) are applied when necessary. Water-level corrections, for example to compensate for gage height, are calculated after each measurement and applied to the recorded values. Daily values are reported as the measurement at 1200 hours in feet below land surface.
MEASURING POINT: Unknown.
TOPOGRAPHIC MAP: USGS Imperial Beach, California, 7.5 minute series.
COOPERATION: The station is operated under cooperative agreement with the Tijuana County Water District.
