A white buoy with an orange marking most likely indicates that you should proceed through the area with caution. The buoy often marks rapids, rocks, or sandbars. A diamond shape with a cross means boats must keep out. A buoy or sign may show only the symbol or may also indicate Swim Area, Beach, Keep Out, No Boats, Closed Area, Dam, etc.
