Flood Warning Extent Reduced


(WCS - 30/2017)

May 15, 2017 – Water levels have continued to recede over the weekend and are not expected to be affected significantly by rain forecast for later this week. This has led to a reduction of the coverage of the Flood Warning.


The Flood Warning is now limited to the upper Tay River where outflow from Bobs Lake has continued but there has yet to be a significant drop of the water level. Several properties around Christie Lake are still flooded. Sections of the Christie Lake North Shore Road has been under water for several days.


Flow of the Tay through Perth is declining slowly at 1 to 2 centimetres (cm) per day as water passes through from Bobs Lake. Some flooding has occurred in Stewart Park and in and near Last Duel Park in Perth.


Not as much rain as was forecast fell over the weekend. Little to no increases in levels occurred in the Rideau watershed or in the areas the RVCA monitors on the Ottawa River - Lac Deschene, Petrie Island and Boise Village. These areas are no longer under Flood Warning status as levels decline by about 10 cm per day.


The water level on the Long Reach of the Rideau River has dropped below the flood level for the access road to Hilly Lane. Flood waters have fully receded at all the rest of the susceptible areas on the Long Reach.


Rideau Canal reservoir lakes, Big Rideau, Upper Rideau and Wolfe, have all been declining with Upper Rideau dropping below the Full Supply level today.


Conditions around rivers and lakes are still hazardous with water levels that are relatively high. Everyone, especially children, are advised to stay away.


The public is encouraged to tag us or share photos of water conditions in their area at RVCA Facebook (RideauValleyConservationAuthority) and Twitter (@RideauValleyCA).


Conservation Authority staff will continue to monitor conditions and will issue updates as warranted.
