The Okanagan Valley in British Columbia is defined by numerous lakes. These lakes are influenced by natural hydrological processes such as flooding from snowmelt and rainfall events, as well as drought conditions resulting from low precipitation. These lakes also experience substantial wave action due to their typically large surface areas and north-south orientations that parallel the prevailing wind patterns in the valley. Water levels within some of these lakes, including many of the valley bottom large lakes, are actively managed by dam structures, with target lake levels established for different months or seasons of the year. These factors have resulted in uncertainty over how the ������������������high water mark������������������1 (HWM) is determined for various lakes in the Okanagan under the provincial Riparian Areas Regulation (RAR; Province of British Columbia 2004). The Ecosystems Section of Ministry of Forests, Lands and Natural Resource Operations (MFLNRO) provides the following guidance to ������������������qualified environmental professionals������������������ (QEPs) to address this uncertainty.
