There are 3 stocks of Chinook in the Chilliwack-Vedder: indigenous summer run fish, entering the system in late June thru August, spawning in late September. This stock is genetically extinct but I’m told a few exist - they were a hoot to fish for in the early 70’s when more abundant.
Next to arrive are the hatchery summer reds , a mix of interior stocks from systems like Bowron River, Finn Creek and Chilko River. These fish spawn late August - early September and are essentially a put and take fishery as wild recruitment is minimal due to poor egg/fry/smolt production.
Last to arrive are the fall whites, derived from Harrison River stock. This is what is in the Chilliwack now and has been for the last month. When fresh and new, the flesh of these fish is pink; almost steelhead flesh coloured. After a week or so in the river this flesh colour fades to the more common white or marbled look. Again, wild recruitment from fall whites, with the possible exception of Sweltzer Creek spawners, is minimal.
