Reel,
Do it b4 the end of June or after labor day unless you are planning to do your water based surveying at night.
During the summer months the lake is overtaken by recreational boaters and PWCs. Usually the traffic doesn't start untill 10 am, after that, its time to move to Owasco.
Also, the floating weeds during the summer all but rule out trolling.
The fishing can be good, just gotta know what you are in for.
Good Luck- Rusty
