As flooding continues in Ottawa along the Rideau River, local conservation
authorities are working to update floodplain maps last completed in the 1980s
and early 1990s. The Rideau Valley Conservation Authority warned Thursday that
water levels are expected to increase 10-15 cm over the next 24 to 36 hours in
Old Ottawa South and in the southern stretch of the Rideau River from Manotick
to Beckett's Landing. via
