Currently, all data for RG33 (9/10/1974 through 9/01/1977) and RG33A (12/05/1977 through 6/05/1997) is combined under RG33A because there was no separate well information provided for well RG33.
Recommendation: If separate location and MP elevation data for wells RG33 & RG33A could be obtained, we could separate the early time frame RG33 data from RG33A. In the mean time, the following corrections are for water level data keyed to well RG33A.
The depth to water varies between the RGWCD and USGS database and the monthly field maps by 1.30 ft during the period 1/15/1978 through 3/05/1979. Then it varies by 0.95 on 4/09/1979 and then matches for the rest of the measurements. This relatively regular variation between the maps and the databases suggests that corrections were applied to the database. Is this so? Should the values in the database be changed to reflect the field sheets?
04/03/1984: DTW difference: RGWCD = 54.84; USGS = 54.88.
