I am from the area and have a cabin on the NE side. Summer fishing can be tough if ya don't know what you are doing. I would definitely recommend a guide for a day our two to show you how to fish this lake. It's one of those lakes where if ya don't know what you are looking for, everything looks good. A guide can show you how to fish the lake and what to look for. Check out Dragon Slayers Guide Service. This is the guide service that Seth Feider put together. There are 3 other guys that guide through this service and all are great guides. https://www.facebook.com/DragonSlayersGuideService/
There are also a few other guides services that are really good. Check out Jeremiah Johnson as well. This dude does some guide trips up there and catches giants. He has taken Zona out quite a few times and done shows with him. https://www.facebook.com/Jeremiah-Johnson-Fishing-446885578696933/
A couple other great guides are Jim DeRosa and Mark Schultz.
If you do go out on your own you will want to play the wind. If the wind is out of the west, fish the west side and if out of the east fish the east side. Both have really really good fishing. Check out Seth Feider's youtube video after his win at the AOY Championship. He spilled the beans on how to catch big fish in the summer and early fall out there. Targetting big boulders with dropshots. It's the best way to catch giants out there. Have fun, Ill be up there Friday :-)
