Channel stability and suspended sediment sources were evaluated in the Coldstream and Vaseux Creek watersheds of the Okanagan Basin of British Columbia. Suspended sediment grab samples were taken at a number of stations throughout the watersheds at regular intervals during 1980. A comparison of sediment concentrations and yields at the various stations showed that the main source of sediments in both watersheds was from failing banks and degrading beds along the lower and middle reaches of the mainstem stream channels. The sediment sources in the Coldstream watershed coincided with reaches in which the channel stability was classified as poor by both the U.S. Forest Service and Aquatic Studies Branch channel stability evaluation procedures. Channel stability in the main source of Vaseux Creek was classified as fair. The reach that is the main source of sediments in Vaseux Creek has frequent valley wall failure scars and was affected by massive scour and sediment deposition during a flood in 1942. There was an
