The Monitor 1998



Bishop Cone Private Well Monitoring
Randy Jackson, Inyo County Hydrologist

In the summer of 1997, the Inyo County Water Department's hydrology staff set up a monitoring network of privately owned wells located near three proposed Los Angeles Department of Water and Power replacement wells on the Bishop Cone. The private well network, established in anticipation of the construction of the replacement wells, provided baseline information on water levels at the private wells. Monitoring continued during the summer of 1998 as one of the three replacement wells was brought into production. There was no detectable difference in water levels from pre-replacement conditions. Monitoring will continue in 1999 in the portion of the monitoring network linked to the remaining two replacement wells.

The Inyo/Los Angeles water agreement requires that LADWP groundwater pumping be managed to avoid causing significant adverse effects to water quality or water levels in privately owned wells in the Owens Valley. Any such effects must be promptly mitigated by LADWP. camas.jpg
