In 2017, the non-profit Living Lakes Canada, began a community-based groundwater level monitoring Program in the Upper Columbia Basin in the interior of British Columbia (BC). In this region the aquifers are generally small and characterized by the mountainous environment. The Program goal is to increase knowledge about groundwater to inform sustainable water management and protection by tracking groundwater levels, engaging partners and citizens in data collection, and sharing the data publicly for others to use. To collect data in a cost-effective way, the Program partners with well owners (such as citizens, First Nations, local governments, and water supply system operators) to track hourly groundwater levels in existing wells. The Program identifies priority areas for monitoring; assesses well suitability for monitoring; establishes monitoring agreements with well owners; secures, installs, and maintains equipment; conducts monitoring; trains and supports well owners to assist with monitoring; and reviews and manages the data. Currently there are 32 Volunteer Observation Wells in the Program. Most of the wells being monitored are not influenced by pumping and these volunteer observation wells complement the eight Observation Wells that are part of the BC Provincial Groundwater Observation Well Network. Data from the Program thus contributes to a groundwater level data set that represents a larger range of conditions, as well as locally relevant aquifer-specific data. The data are shared publicly on the Columbia Basin Water Hub and the BC Real-time Water Data Tool providing multiple viewing and access options to meet the needs of researchers, decision-makers, and citizens.
