Residents near Boisé and Leo lanes in Ottawa's east end are busy filling sandbags and operating sump pumps for the third time in seven years as the Ottawa River once again floods the area. One of the snowiest winters on record in Ottawa contributed to flooding along that river that started last month. Water levels are surging again during a very rainy week. In Cumberland, located about 30 kilometres east of downtown Ottawa, longtime resident Glen Roberts is no stranger to flooding.
