Mono City and Conway Ranch Estates Well Concerns
A few individuals have expressed concerns that changing surface water management may affect the groundwater recharge for domestic wells. The following text from page 31 of the explanatory statement addresses this issue:
"Any change in Wilson Creek flow due to the proposed action would have a negligible affect on the total recharge to the shallow water aquifer above the wells because a) Wilson Creek flows are one of many sources of recharge, b) only minor recharge occurs from the creek in the Conway Ranch area (Applied Geotechnology, 1987), and c) changes in Wilson Creek flows would have a very small effect on the channel losses since the wetted perimeter does not change significantly with flow because the channel is incised.
Recharge to the confined deep aquifer occurs where the shallow water aquifer lies directly above the deeper aquifer and from subsurface groundwater flows from the surrounding mountains (LADWP, 1984). This recharge zone to the deeper aquifer is at higher elevations within the fractured bedrock and along the margins of the unconsolidated sediments (Shown in Figure 7 as the dark gray band)."
