Water supply for Salt Spring Island’s 10,000 residents and an estimated 10,000 annual visitors is derived entirely from the Island’s footprint, from community systems utilizing water from surface water and groundwater sources, together with private wells. Aquifer mapping for Salt Spring Island was conducted by integrating available geological mapping and information from over 2500 well logs using three-dimensional visualization software.
Monthly groundwater budgets were then derived for each aquifer to assess the sustainability of groundwater withdrawals based on available climate data, estimates of groundwater recharge, and an estimate of groundwater demand from domestic, commercial and agricultural users. The results of the budget analysis will be used to inform groundwater licensing decisions by the BC Ministry of Forests, Lands, Natural Resource Operations and Rural Development under the Water Sustainability Act, and to support water management initiatives being undertaken by local authorities and community groups.
This forms one in a series of Community Watershed Stewardship Presentations by Salt Spring Island Watershed Protection Alliance (SSIWPA).
