There are two speed limits posted on the lake. The Main Lake Ski Area buoys are posted as 35 mph. The rest of the lake, however, is posted as "no-wake" which means boats may travel up to 5 m.p.h. as long as it is not creating a wake. The boat is required to maintain no-wake even if this means they must travel at a lower speed. In the Main Lake, this includes the entire perimeter along with all coves. The entire East Bay is also a no-wake area.
Flags
Boaters are also asked to be aware of the flags used on the lake. There are three flags used; red flags, mean the Main Lake is closed to boat traffic, yellow flags mean the Main Lake is restricted to 5 mph and green flags mean there are no lake restrictions. These flags are posted at Holiday Harbor to the sides of the flagpole, and at the East Port launch ramp.
