It's always nice to see a new name on the site.
East and West lake have smaller walleye, some biggies are caught there but most are the size you're catching.
The Picton harbour is not a bad spot, if your boat is small the harbour is sheltered nicely. We've caught 12lbers from the docks on fall evenings. Jointed floating body baits. We've caught pike, walleye, and salmon, all in the Picton harbour on the docks.
The water can get nasty farther out towards Glenora. If the weather is good you could put in at the Glenora Marina or the other side of the ferry. Deep divers are popular out there now. I'd pick a chad type colour, silver/grey with a slight purple to black on the back of the bait. The Dr. Death colour is one I found this year thanks to the good folks here. I may give my "CC chad"
of the same colour a break for a while. The Dr. is in and looks good, but have yet to try it.
There is some interesting info and maps in the "Info. Articles" in the above header.
As for East & West lakes the bass are very good on both and I personally know of trout that come into those lakes from L. Ont. spring and fall.
I hope this is of some help. There are much better fishermen here than me. I'm sure some will post more good advice for you.
