Watercraft noise levels were measured annually from 2009 to 2013 at 10 shorezone locations for five to six sampling periods (ranging from four to 12 days) from May through September. Sampling periods are comprised of both weekends and weekdays, allowing for analysis of the differences in noise levels or exceedances between days in the week. The monitoring periods include low, medium, and high watercraft use times throughout the day (7 AM to 7 PM). All noise events are individually analyzed and categorized by a trained noise technician.
