Key Findings
This map identifies and delineates surface water protection areas across Bowen Island, including riparian zones along waterways, wetlands, lakes, and their buffer zones. Management recommendations emphasize maintaining 30-meter no-development setbacks for riparian areas to protect fish habitat, water quality, and ecological functions. Wetlands are recognized for their critical roles in water storage, sediment and pollutant retention, nutrient cycling, and water quality maintenance. The map shows the spatial distribution of shallow dug wells and springs across the island, highlighting the connection between surface water protection and groundwater resources.
Methodology
GIS mapping using satellite imagery at 1:10,000 scale
Map Descriptions
Page 1: Map of Bowen Island showing surface water protection areas with legend. The map displays the entire island with cadastre (property) boundaries shown as white lines. Riparian zones are shown in teal/cyan along waterways and coastlines. Wetlands are displayed in blue, with 30-meter wetland buffers indicated. Lakes are shown in dark blue with associated buffer zones. Shallow dug wells are marked with point symbols distributed across the island, and springs are also marked with point symbols. The map includes a north arrow and scale bar (1:10,000). Two information boxes on the left side provide management recommendations for riparian zones and wetlands. The island is oriented with north toward the top of the page, showing the characteristic irregular coastline and internal water bodies of Bowen Island.

Two photographs appear in the left margin: one showing a riparian forest zone with trees along a waterway, and another showing a wetland area with water and vegetation.
