a Fence installation date is based on historical timing information and the first observation of migrating adult sockeye.
b Fence removal date is based on historical timing information and the last observations of migrating adult sockeye.
c Spawning ground surveys were conducted in Cultus Lake, however, no sockeye spawning was observed.
