The SHIM method has been used in the Upper Salmon, West, Nathan, Palmateer and Little Campbell watersheds, as indicated in the image on the right. Fish sampling to determine fish species presence and distribution has been conducted throughout the municipality, and the data is monitored and updated early.
Because of the extensive mapping and inventory work LEPS has conducted since 1993, data is available on stream locations, habitat features and fish presence throughout Langley.
