CRYSTAL LAKE – America’s Cardboard Cup Regatta was canceled Thursday without a rescheduled date because of the high water levels in Crystal Lake, according to an alert on the Crystal Lake Park District’s website. Unfavorable weather conditions, including lightning, postponed the event from its original date on June 17, but recent heavy rain only has added to problems with the lake’s water level. Crystal Lake’s Main and West beaches have been closed since Tuesday and will remain closed through Monday because of recent flooding. Regatta co-chairman Bryan Javor said he was told the bacteria levels in the lake were too low to meet a safe threshold for the event.
