Lots of clean fish in the whole fishable section until closing day. You just have to avoid redds. Truth is alot of the "FLY WATER" is actually redds by way of its nature. The Chilliwack has early, mid and late returning fish and
clean fish can be found throughout the river.
Often "uninformed" anglers have a false belief that fishing lower in April is better for the fish when actually it is not, proven fact is many late run steelies are low river spawners and fishing shallow gravelly sections in April is fishing redds. If you are encountering many dark fish in a certain section during April, do not feel they are not spawning because you are low on the river.
As for the May fishery, it is really not well thought out, and truthfully the river is almost always chalky and hardly fishable, but there is the years when it does fish and I myself partake once or twice.
I have read alot of sillyness about closing above the crossing in April. truthfully my experience is some great fish can be found in that section and since the river is far longer than the fishable section, the upper is still protected by way of the regulations.
These comments are almost always put out there by anglers who only fish the lower section, which by the way is not even historically the Chilliwack river, but a man made stream created from draining Sumas lake.
