From our experiences you will have to be very careful in the Keys (awesome neighborhood). Be very considerate as there are many uptight activist that live in this tight community.
I believe under 1992 built boat you will have to be around 90db and 1993 and newer 86db. or less. on the California Side.
If you stay off plane close to shore you may stay out of trouble.
You will need to be very carefull on the Nevada side, they are very strict and you will get cited with your set up if you meet up on the lake on plane.
my .02, get some mufflers so you can enjoy the awesome lake and not always looking over your shoulder just asking for attention from the law.
Have fun as it is a Beautiful Alpine lake. Don't forget to check out GarWoods for lunch up north and Emerald Bay in the South.
