Cooperative Groundwater Management Group Groundwater Elevation - Groundwater Depth

Well: T27S/R39E-07 R01 (Inyo Well) This hydrograph shows a very consistent water level decline of approximately 0.9 ft/yr since 1945 Note the inconsistent readings from 1962 and 1970. These inconsistencies can be explained by possible water level measurement/recording errors, pumping test in the well (re-development attempt), or seismic activity.
