Phillips River supports five species of Pacific salmon; Coho (Oncorhynchus kisutch), Chinook (Oncorhynchus tshawytscha), Sockeye (Oncorhynchus nerka), Chum (Oncorhynchus keta) and Pink (Oncorhynchus gorbuscha). Of the five species, pink salmon escapements are the largest with even year runs averaging 186,400 between 1985 and 1994 (Hatfield Consultants Ltd.). Between 1991 and 1999, >210 meters of bank erosion occurred at Bend B on the Phillips River. Between 2000 and 2005 the left bank of the Phillips River continued to erode at an annual rate of approximately 5.8 meters per year. The Phillips River was assessed by M. Miles and Associates Ltd. in 2000 and concluded that continued bank erosion at Bend B could impact the mainline road and Bend A if nothing is done. Silt generated as a result of the erosion at Bend B has likely caused aggrading of spawning and rearing habitat downstream as well as reduced incubation success.
In 2005 M.C. Wright and Associates and representatives of Fisheries and Oceans Canada (FOC) inspected Bend B to determine the extent of erosion since it was last measured in 2001 and to determine what works would be required to protect Bend B from further erosion. At this time there was 62 meters of riparian forest left between the Phillips River and the Phillips River Mainline logging road. It was concluded that if nothing was done then there was a high likelihood the road would eventually be lost and negatively impact the recovering Bend A. There was also a high risk the Phillips could eventually jump its bank and flow into Clearwater Creek, destroying valuable spawning and rearing habitat. This would have severely impacted the already declining wild salmon populations.
In 2006, M.C. Wright and Associates was hired to collaborate with the Department of Fisheries and Oceans to produce a prescription outlining the design and procedures to protect Bend B from further erosion. The project received approval from the Land Based Investment Program of the Forest Investment Account (FIA) to carry out the prescribed bank protection works during the 2006 Fisheries Window.
