I'm going to be fishing Lake George middle-late June this year. Any tips? Last year the water was about 65 degrees at that time. 

I did manage to pull out an 8 Pound Largemouth from about 10 ft deep of water. Trying to get another nice one this year, haha. 

SMB tend to be around the rock reefs and sunken humps in the southern to middle half of the Northern Basin, LMB are concentrated in the weed beds at the very northern tip of the lake. Though you can find them pretty much anywhere that time of year, 25-30 ft depths are key.

You can purchase a publication, I think it's sold at Walmart - put out by Sportsman's Connection, which covers the various regions in NY.  I think there are 4 or 5 separate books for the different regions.  There is one with a Lake George map in it along with tips for fishing the different spots on the lake and what lures and bait to use.

You might also check the NY DEC web site as well as the Adirondack Forum for additional information.  

Hope this helps.  Good luck on your June trip.
