Watershed Conditions Statements

Measurements on the Ottawa River indicate that water levels are stabilizing. This Flood Warning applies to areas around Lac Deschene, at Petrie Island and at Boise Village to the east of Cumberland. All locations covered by this statement are expected to have river water levels stabilize this morning and possibly reach peaks this afternoon or evening. There is no significant rain presently forecast that would cause levels to rise again. The decline water levels may be prolonged by releases from upstream dams as excess water from the more northerly parts of the watershed pass through the system. It will take…
Water levels continue to rise but at a slower rate as the rain ends This Flood Warning applies to areas around Lac Deschene, at Petrie Island and at Boise Village to the east of Cumberland. All locations covered by this statement are expected to have river water levels stabilize through today as the rainfall system passes out of eastern Ontario. A peak is expected to be reached by tomorrow on the Ottawa as the flows in the tributary rivers reach peaks through this evening and overnight. Some more rain is in Ontario Ministry of Natural Resources and Forestry weather forecasts…
 The rain is forecast to tail off today and tomorrow in Eastern Ontario finishing with a bout of freezing rain and snow flurries in some locations. Flows in the Rideau system are now not expected to reach flows experienced in the spring freshet (defined as a flood of a river from heavy rain or melted snow). The rate of rise in the Rideau and its tributaries is slowing as the lower reaches of the system stabilize. Levels on the Long Reach will decline to navigation levels and access to Hilly Lane and its neighbours will improve through the coming week.…
Water levels in the Rideau Valley are expected to reach levels previously reached on April 7. Rainfall will continue to cause levels to rise again inundating those locations flooded recently in the spring freshet. Road ways in the communities on the Long Reach of the Rideau River between Kars and Kemptville have already been water covered or will be later today. Belmont Avenue and the Windsor Park pathway in Ottawa South and Brantwood Park in Ottawa East will be flooded again. No other flooding in the urban area adjacent to the Rideau River is expected to be flooded. All of…
Flooding is expected in the Rideau River watershed today and through the weekend. Previous rain from the beginning of the week has increased water levels throughout the watershed. Parks Canada staff have been making adjustments at all dams to reduce the water levels with some success. However, there is still excess water in the Rideau Canal reservoir lakes. Christie Lake on the Tay River, is expected to have further flood issues as water is released from Bobs Lake to relieve ongoing high water there. Releases from Big Rideau Lake will have to be made today which will increase flows downstream.…
Rain forecast for Friday and Saturday is expected to cause levels to increase again.. Parks Canada staff had begun preparations for the opening of the Rideau Canal navigation season prior to the heavy rain last Monday. Dams that had been closed had to be re-opened to pass water through the system to bring levels down. The level on the Long Reach had begun to decline but will increase again due to rain that is forecast for Friday and Saturday. A widespread weather system is forecast to drop a two day total of 35 to 70 millimetres of rain on Eastern…
