Slough in the Fraser River’s South Arm, Flowing Towards the Mouth (winter 2019)
The Fraser River, the longest in British Columbia, flows into the Pacific through three distinct arms that traverse the Metro Vancouver Region and form a Delta with extensive estuarine saltmarshes, mudflats, floodplains, sloughs, and channels. The Delta is recognized as a critical migratory stopover area, providing feeding and roosting sites to about 250,000 wintering waterfowl and one million shorebirds. It also supports critical feeding and rearing areas for salmon.
