Yeah, unless you are a nature nut and can be entertained. It can be pretty troubling when you fork over cash for gas and what not for not much of anything.
Derby Reach was always a fun place to go, you used to be able to camp right by the river too.
Peg Leg is good too if you got a quad, rip up to the far end of towards harrison mouth is a nice spot you can walk it as well but its not much of a fun hike, waters nice and slow there though you can almost do the tradition float fishing like you'd do for trout as a kid on a small lake. Might be to slow for bar fishing, mind you when I think of bar fishing, I always uses roe + spin 'n glos lol. so you always needed good flow to keep the glo up and spinning.

Deroche used to be great but again the general public farmers to blocked off a lot of the trails for similar reasons to Island 22, fishermen not respecting the property or the reserve.
Grassy Bar, I don't know if there is much fishing to be had there but it might be worth looking at its, kinda troubling though because its rather close to the Eco reserve, so I don't know if you can even access it.
Otherwise all thats left up in that area is Queens Island and Wellington Bars and right in the middle is the Island 22 Boat launch.
You may consider trying;
Brownsville bar (off scott road)
Coquitlam River bar (Under the Port Mann)
Two bit bar (Not sure exactly where but its in the Fort Langley area)
Mission Bridge
Pitt River
But be careful some of these locations require a tidal license
