Physiography
The low lineament density bedrock is located in the uplands. The bedrock consists of Paleozoic interfoliated schist and paragneiss. The bedrock has moderate hydraulic conductivity. This unit has the highest recharge rates for the Okanagan area, suggesting an unconfined aquifer. Shallow bedrock groundwater flows toward Mission Creek Valley Fill aquifer and deep bedrock groundwater flows toward Okanagan Lake, which designates an important regional discharge. The deep bedrock groundwater flow is less important than the shallow one because the permeability of the bedrock decreases exponentially with increased depth in the Okanagan Highlands.
Hydrogeological region	Cordillera
Hydrogeological context
Relief	Located in the uplands, the low lineament density bedrock has moderate to high slopes along the river, mostly in the southern part of the hydrogeological unit. Elevation decreases from west to east, from 2000 to 1200 m.
Area	164.00 km2
Lithology
Description	The hydrogeological unit is located in the uplands. The bedrock consists of Paleozoic interfoliated schist and paragneiss.

Regional discharge

Description	Shallow bedrock groundwater flows toward Mission Creek Valley Fill aquifer and deep bedrock groundwater flows toward Okanagan Lake. The deep bedrock groundwater flow is less important than the shallow one because the permeability of the bedrock decreases exponentially with increased depth in the Okanagan Highlands.
