I had the same kind of deal. i bought a used POS kayak on craigslist fro dirt cheap and was able to fish a lot more places.
Check out lake park. I have caught 20# blues in the spring and 8-10# blues occasionally in the fall mostly 2-5#rs with cut shad or perch heads.
when the sandies are shallow you can limit quick with a chrome slab.
bass are all in the buck brush and willow in the slough right now. have not caught any big ones but have got a ton of little guys. still fun
