Mission Creek Valley fill aquifer (No. 461) unit description

Update:2014-03-10
Mission Creek Valley Fill aquifer consists of sands and gravels, underlying a thick till unit (4-75 m). It is underlain by moderate lineament density bedrock aquifers and by moderate to low lineament density aquifer. The till unit generates confined conditions for the aquifer. The hydraulic conductivity and the recharge are moderate. Groundwater flows toward Okanagan Lake and is exploited for domestic uses.
