Fishing opps. off Mercer Island?

Does anyone know if there is any viable fishing opportunities off of Mercer Island? I only have a couple of hours on Saturday morning to fish, and I have to stay close... Any ideas???

If you are really desperate - some guys will flyfish for perch. Look for submerged weed beds 8-20 deep. Use small wooly-bugger type patterns - try olives, reds and yellows. You might also try throwing some larger streamers for bass around some structure if you have access to a boat.

I thing most of the trout, and there are some very large ones, in LW get caught by the trollers on spoons and such.
i recently move to washington from the southern appalachians and have been fishing ever since i got here. ive yet to catch a fish in lake washington. if any one can help let me know.

also, im interested in any info i can get on small stream (appalachian style) fishing thats closer than yakima.
