Despite some heavy rains and an earlier than normal spring in Thunder Bay Ont., the Lakehead Region Conservation Authority (LRCA) is not forecasting significant flooding in the area. CEO Tammy Cook said despite recent rains, rivers in the northwestern Ontario city are experiencing water levels that occur about once every five years. "We aren't seeing any significant flooding at this time," she said. "We are anticipating up to another 20 millimetres overnight, but we still think that area water courses will remain within their banks," Cook told CBC News in an interview Monday.
