Title
Grafton Lake Watershed, Bowen Island / Nex̱wlélex̱wm
Description
This map shows the Grafton Lake Watershed on Bowen Island (Nex̱wlélex̱wm), depicting detailed topography, water features, streams, riparian zones, protected areas, and land stewardship designations. The map includes information about fish-bearing and non-fish-bearing streams, wetlands, major water supply areas, and protected reserves including the Eco Reserve and Art Rennison Nature Reserve. The map uses a 1-kilometre coordinate grid and includes inset maps showing 3D perspective views of the island and water supply watersheds across the entire island.

Key Findings
This watershed map documents the Grafton Lake watershed area on Bowen Island, identifying critical water supply sources including surface water supply from Grafton Lake and associated creeks, as well as aquifer locations. The map delineates watershed boundaries, protected conservation areas, and distinguishes between fish-bearing and non-fish-bearing streams to support habitat and water resource management.
Methodology
Map created using topographic and geographic data at 1:9,090 scale using UTM NAD83 coordinate reference system.
Map Descriptions
Page 1: Detailed topographic map of Grafton Lake Watershed on Bowen Island showing elevation contours, streams (both fish-bearing marked in blue and non-fish-bearing marked in lighter blue), lakes and ponds, wetlands, riparian zones, protected areas (Eco Reserve, Art Rennison Nature Reserve), Crown Lands, municipal parks, and Agricultural Land Reserve. The map includes Mt Gardner at 728m elevation, Grafton Lake as the central water body, the Grafton Water Plant and Dam locations, and numerous labeled creeks and tributaries. Inset maps show 3D perspective views from northwest and south, plus a small overview map of all water supply watersheds on the island. Scale is 1:30,000 with 1-kilometre coordinate grid. scientific advisors Will Husby, Jeff Matheson, Bob Turner, and Alan Whitehead. Scale, projection, and disclaimer information are included at the bottom. Contact information for the cartographer (jdowler@cosmicidea.com) is provided.
