The summer could be another very busy one on Candlewood Lake. The state is reporting new vessel registrations have increased dramatically over last year.  There is also a sizable increase in safe boating certificates and boating education class registrations.  The Candlewood Lake Authority says there is unprecedented demand for people looking for dock space. In the off-season, the CLA Marine Patrol was expanded and will have additional patrols out this summer.  CLA officials asked that boaters be responsible and courteous of others on and around the lake, and be sure everyone has a flotation device before heading out to the water.  They also urged boaters to keep sound from their vessel to a level that does not disrupt others.
