A (gravel) bar is an accumulation or island of gravel along a river. This term is more specifically used for the lower section of large river systems such as the Fraser River, Columbia River and Skeena River.
As the river rises, falls, transports gravel, bars are constantly moved, destroyed and formed. Bars are usually where good fishing for salmon and other freshwater fish can be found. On the Lower Fraser River between Chilliwack and Hope, bar fishing for chinook salmon is commonly practiced in July and August.
