Modelling in the Upper Salmon River, Coldstream and Tappen areas has allowed refinement of boundaries and clarification of hydraulic relationships between important local aquifers. Aquifer sheets have been refined based on these results to assist in sustainable management and effective use of groundwater resources in the aquifers.

Audience:  Government and Public

The scale of this study was sufficient to refine aquifer boundaries and improve the understanding of aquifer hydraulics on a regional scale. The results have highlighted the widespread risk of flowing artesian conditions. However, the scale of the study was too regional to provide a clear understanding of why some wells are flowing artesian and some are not, and hence, how to assess the risk for new well construction. The complexity of stratigraphy in the flowing wells at Coldstream Ranch and Westwold could not be captured in a regional groundwater scale geologic model. Additional local scale geologic studies and numerical modelling are recommended to better understand the interaction between stratigraphy and geology in generating local artesian conditions.
