Site Description for Pala Park (8S/2W-19A1-6)
LOCATION: Latitude 33º 28' 19.67" N, longitude 117º 07' 06.86" W (NAD83) in Riverside County, California. The wells are located in a vault approximately 126 feet north of the intersection of Canterfield Dr. and Temecula Ln. on the western boundary of Pala Park in Temecula, California.
SITE INFORMATION: Land-surface altitude is 1,017 feet above mean sea level (NGVD29) from 24,000 scale topographic map.
INSTRUMENTATION: In Situ transducers, In Situ barometer, with a Design Analysis logger and GOES transmitter. Water levels are logged at 15-minute intervals. A 12-volt rechargeable battery provides power.
WATER-LEVEL RECORD: The period of record for intermittent and daily water-level measurements is listed below.

WATER-LEVEL MEASUREMENTS: Water levels are measured manually each month 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. In the annual data report daily values are reported as the measurement at 1200 hours in feet below land surface.
MEASURING POINT: Measuring point #1 is at an even level with the top of the vault. Measuring point #2 is a black mark on the top of the PVC casing.
