Method used to determine depth to water: L, interpreted from geophysical log; R, reported, method not known; S, calibrated steel-tape measurement; T, calibrated electric tape; V, calibrated electric cable (wire line or iron horse).

Quality-assurance flag: A, anomalous value; AT, water level does not agree with second access tube in same open interval; C, affected by  well construction, queried where uncertain; D, dry hole; H or L, static water level in well is elevated above (H) or depressed below (L) regional ground-water level; R, well pumping or recently pumped; N, water level affected by nuclear test; X, water level corrected for borehole deviation; --, no flag applied

Water above bottom of open interval: length of water column in well from top of water to bottom of open interval listed in table 1.
