The lakes of the central and north Okanagan are crucial for economic, recreational, social, and environmental services such as water supply. With ongoing growth in the region, risks to these key resources are increasing. Main stem lakes such as Kalamalka and Wood, with their large littoral zones, are at greatest risk with increasing population pressures.

Audience:  Government and Public

The objectives of this project to: - To investigate the long-term potential threats from boating activity on lake source water protection for the municipal and domestic intakes on Kalamalka Lake; - Understand the spatial distribution of boating activity using existing information to understand where primary recreational pursuits are occurring in relation to water intakes; - Understand the spatial location of key risk areas based upon environmental factors including substrate type and proximity to source water intakes; - Understand what are key factors that increase risk to source water intakes, such as sediment disruption, spills, marina facilities, etc. and identify key pathways or mechanisms that could result in contamination at the point of intake; - Understand what types of boating activities pose the greatest risks based upon vessel types, sizes, and primary areas of use on both Kalamalka and Wood lakes.
