Land Use Planning for Watershed Management

Recent work under this stream has involved data gathering and analysis to inform future policy and regulatory decisions. 

Groundwater Recharge Potential 

The Salt Spring Island Groundwater Recharge Potential Mapping Report was released in October 2019. 

This report is based on a new approach to determining aquifer recharge potential and considers spatial variability of precipitation, surplus, land cover, soil and geology, slope, and faults and contacts between bedrock strata. The report describes the potential for groundwater recharge for defined community aquifers on Salt Spring Island. Lithology, land use land cover, precipitation and slope were determined to be the most influential factors controlling recharge potential, followed by lineament density, soil type and drainage density. The report maps aquifer recharge potential on Salt Spring and shows a high contrast between areas with low recharge potential and areas with moderate to high recharge potential. 

Groundwater Well and Lake Monitoring Pilot Project

Currently, work is ongoing on a pilot groundwater well and lake monitoring project  funded in part by a Real Estate Foundation of British Columbia Grant that has 12 volunteered domestic groundwater wells and 5 island lakes under observation with automated monitoring equipment. These monitors are measuring water level fluctuations and temperature changes. The well monitors are also measuring salinity.  This monitoring will help inform how natural and anthropogenic changes will impact watershed hydrological function and water use on Salt Spring Island.

Results of this pilot project will be reported out to the community in March 2020.
