Flood forecast #15 - May 5

Current situation
At 3:00 p.m., the Red River in downtown Winnipeg was at 15.6 feet James and is declining at about 1/3 of a foot per day. The current river level is 9.1 feet (2.8 metres) above normal summer water level.

South of the Floodway, the Red River is currently at 753.9 feet (229.8 metres), down 9.5 feet from the April 20 peak of 763.4 feet (232.7 metres). The Floodway control gates are still in operation, as is the Portage Diversion on the Assiniboine River.

Provincial flood forecast
The Red River level in Winnipeg will continue to decline steadily based on favourable weather. The rate of decline will increase to about 1/2 foot per day once the Floodway control gates cease operation - which may occur by Monday.

By May 15, the Red River level in downtown Winnipeg is estimated to be down to 10 feet James. The river level will likely be below the river walkway by May 18 - prior to the May long weekend. Both of these estimates are assuming normal weather conditions. A heavy rainfall would delay the river decline.

Weather forecast
Environment Canada Icon indicating a link which will open up a new browser window and take you to a Web site outside of the City of Winnipeg's Web site indicates possibility of light rain today and on Monday otherwise a mix of sun and cloud - no accumulation is indicated.

Flood control activities

  • Sand bag dikes
    All sandbag dikes may now be removed. Water and Waste, in conjunction with Public Works, developed a notice Icon indicating a pdf file which will open up a new browser window. (pdf - 20kb) that has been hand delivered to properties. The property owners are responsible for the removal and disposal of the sandbags. Removal is recommended in a timely manner due to riverbank stability concerns.
  • Sandbags on sanitary sewer manholes
    These sandbags are being removed as of today with completion expected by Tuesday, May 9.
  • Flood pumping stations
    20 flood pumping stations remain activated along with 3 temporary pumping locations (portable pumps) on the City's combined sewer and land drainage sewers.
  • Flood control gates
    There are currently approximately 100 flood control gates in operation to protect the City's sewer system from river water.
  • Basement flooding
    With continued above normal / elevated river levels, there remains an increased risk of basement flooding with the occurrence of moderate to heavy rainfall.

Flood forecast #14 - April 28

The first peak in Winnipeg occurred April 7, at 20.35 feet James. This is the second highest river level in Winnipeg since the Floodway was built. On that day, the natural level in downtown Winnipeg without operation of flood control works would have been 23.5 feet James.

The second Red River peak (based on the maximum river level upstream of Floodway) occurred on April 20 at 18.3 feet James. On that day, the natural level in downtown Winnipeg without operation of flood control works would have been 27.1 feet James.

Current situation
At 2 p.m., the Red River in Downtown Winnipeg is at 17.6 feet James and is declining at about 1 inch per day. The current river level is 11.1 feet (3.4 metres) above normal summer water level.

South of the Floodway, the Red River is currently at 761.0 feet (232.0 metres), down 2.4 feet from the peak on April 20 of 763.4 feet (232.7 metres)

The river flow through the City downstream of the Floodway is about 46,700 cubic feet per second (cfs) while the flow in the Red River Floodway is about 24,000 cfs. The peak floodway flow in 1997 was 66,000 cfs.

Provincial flood forecast
The river level in Winnipeg will continue to decline very slowly based on favourable weather. The Red River level at James will likely be in the 16.5 feet range by May 5.

Weather forecast
Environment Canada Icon indicating a link which will open up a new browser window and take you to a Web site outside of the City of Winnipeg's Web site indicates a possibility of rain over the next few days, although no accumulation is indicated.

Flood control activities

  • Sand bag dikes
    Most, but not all, sandbag dikes may now be removed. Removal is recommended in a timely manner due to riverbank stability concerns. There are a dozen properties where sandbag dikes should remain at this time. Water and Waste, in conjunction with Public Works, have developed a notice Icon indicating a pdf file which will open up a new browser window. (pdf - 20kb) where sand bags may be removed and another notice Icon indicating a pdf file which will open up a new browser window. (pdf - 20kb) for where sand bags are still required. These will be hand delivered to appropriate properties. Property owners are responsible for the removal and disposal of the sandbags. Property owners should not remove their dikes until such notice is delivered to them.
  • Sand bags on sanitary sewer manholes
    With high river levels and a continued risk of rain in the next few weeks, sand bags on sanitary sewer manholes will remain in place at this time. Sand bags provide an extra level of protection to the sanitary sewer system and help prevent basement flooding.
  • Flood pumping stations
    Over 20 flood pumping stations are activated along with 13 temporary pumping locations on the City's combined sewer and land drainage sewers.
  • Flood control gates
    There are currently approximately 130 flood control gates in operation to protect the City's sewer system from river water.

Flood forecast #7 - April 8 (5:30 p.m.)

The first peak in Winnipeg occurred yesterday, April 7, at 20.35 feet James. This is the second highest river level in Winnipeg since the Floodway was built.

Current situation
At 5:30 p.m., April 8, the Red River is at 19.3 feet James and the decrease has flattened out.

Provincial flood forecast issued this afternoon
The river is expected to remain in the 19.3 to 19.6 feet James over the next few days. However, a second peak is expected to occur after Easter (April 20) when the floodwaters from the U.S. pass through Winnipeg. This second peak for Winnipeg has been increased slightly and should be in the range of 19.5 to 20.0 feet James.

This second peak has the potential of being higher if adverse weather develops. There is a one-in-ten chance that a crest of 21 feet James could occur if a rainstorm of 35 mm or more occurs in the next several weeks.

Flood response as of April 7

  • City officials continue to recommend that property owners build sandbag dikes to the levels staked and marked by City survey crews. This mark allows for 35 mm (1 1/2 inches) of rain and 0.6 metres (2 feet) freeboard. (Freeboard is defined as 2 feet of dike height above the forecasted river level)
  • The second peak could be about the same as we have already experienced, but it could higher. The stakes marking dike heights will accommodate higher levels.
  • Levels will be closely monitored and property owners will be advised of any changes.
  • No problems with dikes were reported overnight. Sandbag dikes built to date are holding well, and City crews are visiting these sites on a regular basis to monitor the situation.
  • Preparation of sandbags continues: 110,000 have been prepared to date; 100,000 of which have been delivered or picked-up. Sandbags will continue to be produced and delivered to identified locations as required.
  • If property owners require technical assistance in building sandbag dikes, they are advised to contact us.

Flood forecast #6 - April 8 (11 a.m.)

The first peak in Winnipeg occurred yesterday, April 7, at 20.35 feet James. This is the second highest river level in Winnipeg since the Floodway was built.

Current situation
This morning, April 8, the Red River has dropped to 19.4 feet.

Forecast (based on April 7 Provincial forecast)
The river is expected to remain in the 19.3 to 19.4 range over the next few days. However, a second peak is expected to occur after Easter when the floodwaters from the U.S. pass through Winnipeg. This second peak for Winnipeg is expected to reach 19.5 feet James.

This second crest has the potential of being higher if adverse weather develops. There is a one-in-ten chance that a crest of 21 feet James could occur if a rainstorm of 35 mm or more occurs in the next several weeks.

Flood response as of April 7

  • It is being recommended that property owners who have been identified as requiring sandbag dikes, build their dikes to the levels marked and staked by the City.
  • Two sandbagging machines are operational and are capable of producing approximately 60,000 sandbags per day, as required. In total, 71,500 have been delivered or have been made available to locations requiring dikes. Sandbag dikes built to date are holding well, and City crews are visiting these sites on a regular basis to monitor the situation. Sandbags will continue to be produced and delivered to identified locations as required over the weekend.
  • Efforts are continuing to protect the City's sewer system from river water back-up. Currently, 32 flood pumping stations are activated and 167 flood control gates are operating.

Flood forecast #5 - April 6

Current situation
The Red River has risen above the previously forecasted peak level of 19.5 feet. Currently, the Red River downtown is at 19.9 feet James Avenue datum. The Floodway was put into operation at 5:30 p.m. yesterday.

Forecast
As of today, the Province is forecasting a possible rise of the Red River to 20.5 feet James by tonight or tomorrow morning. Thereafter, the river level is expected to stabilize in the 20.0 to 20.5 feet range for a day or two. This will be followed by a decline, but a second peak will occur after Easter when the river water from the U.S. passes through Winnipeg. This second peak for Winnipeg is expected to reach 19.5 feet James.

There is a possibility that a heavy rainfall may cause the second crest to be higher, although such rain is not yet in the weather forecast. It is estimated that there is a 10 percent chance that the level in downtown Winnipeg may rise to 21 feet James in the event of a 35 mm rainstorm.

Flood response

  • Properties at risk of flooding based on this revised forecast have been identified and notification is being provided to those locations where sandbag dikes are recommended.
  • City crews continue to prepare and deliver sandbags, and are working to operationalize two sandbagging machines.
  • 72,000 sandbags have been prepared, and as of last night 14,000 have been delivered.
  • The City has partially activated its Emergency Operations Centre, and continues to monitor the situation closely.
  • If property owners require assistance in building sandbag dikes at identified locations, they are advised to contact us.

The City of Winnipeg sewer system is protected from river water back-up. For a level of 21 feet James, 32 flood pumping stations will be activated and 167 flood control gates will be operational. In addition, there will be 37 temporary pumping locations and 138 manhole sealing locations.

top of pageTop of page


Flood forecast #4 - April 5

Current situation
The Red River has risen more quickly than previously forecasted. Currently the Red River downtown is at 18.5 feet James Avenue datum. The sheet ice has broken and is moving through the City. The Province has increased the flow into the Assiniboine Diversion. The Floodway gates are expected to be in operation at 5:30 p.m. today.

Public Works began delivering sandbags last night - the first location being the Winnipeg Rowing Club. Sandbag delivery is continuing to residents whose properties have been identified and who agree to receive the sandbags. There are some properties that are refusing to take delivery. These properties are typically ones which require a low sandbag dike for "freeboard" protection. 72,000 sandbags have been made.

21 flood pumping stations have been activated and approximately 137 flood control gates are operational.

Forecast
The Red River is expected to rise to 19 feet James by tomorrow morning and possibly to 19.5 feet James if an ice run develops. Thereafter, the river level is expected to stabilize in the 18.5 to 19.0 feet range. The expected peak for Winnipeg is 19.3 feet James sometime near Easter.

The City of Winnipeg is prepared for a Red River water level peak of 19.5 feet James. The weather is positive as no rain is expected for the next several days.

top of pageTop of page


Flood forecast #3 - April 4
This is the first flood forecast where river water levels are forecasted for each day in the coming week. They are rough estimates since there are no actual measurements of river flows due to ice conditions.

Current Situation
The Red River has risen quickly over the weekend and Monday - roughly 10 feet over 3 1/2 days. The Red River downtown is currently at 14.3 feet James Avenue datum. The sheet ice has moved on most of the river in Winnipeg, but has not moved upstream (south) of the Floodway. The Floodway gates are not yet in operation.

Presently, nine flood pumping stations have been activated and seven more will be activated today. Approximately 104 flood control gates are operational. 72,000 sandbags have been made. The delivery of sandbags to homes requiring sandbagging will begin.

Forecast
The Red River is expected to rise to 18.8 feet James, or another 4.5 feet over the next 8 days. Below are the daily rough estimates:

April 5 15.7 feet James
April 6 17.0 feet James
April 7 17.5 feet James
April 8 18.0 feet James
April 9 18.3 feet James
April 10 18.5 feet James
April 11 18.7 feet James
April 12 18.8 feet James

The City of Winnipeg is still planning for a Red River water level peak of 19.5 feet James. The weather is positive as no rain is expected for the next several days. The Province is expecting to begin operation of the Floodway gates on Friday, April 7th.

top of pageTop of page


Flood forecast #2 - March 31
The updated flood outlook reaffirms the outlook issued last week. There was concern that with the recent rain, the flood outlook had changed. This is not the case for Winnipeg.

At this point, with little additional precipitation, the flood forecast is for the Red River to crest in downtown Winnipeg at between 18 to 19 feet James between April 14th to 18th. With unfavourable weather conditions, it would be higher, at about 19.5 feet James.

Thus the City's Water & Waste Department and Public Works Department will continue preparing for a river level of 19.5 James. A flood of this magnitude would require the activation of 29 flood pumping stations and 173 sewer control gates as well as setting up 26 temporary pump locations. Approximately 118,000 sandbags would also be required at 48 homes within Winnipeg. The City's flood control plan will be adapted as more accurate flood forecasts become available over the next week, in particular once the ice releases. The electronic flood manual scenario is 211.

Currently, the Red River level downtown is 4.6 feet James Avenue datum. Starting this weekend, it is expected that the Red River will rise a foot or two per day. The Floodway will likely be activated sometime late next week.

The weather forecast is currently calling for light rain for Wednesday and Thursday. We will likely be issuing more frequent flood forecasts starting on Monday, April 3.

Flood forecast #1 - March 24
This afternoon, Manitoba Water Stewardship has issued its second long range flood outlook indicating the revised flood potential across Manitoba for the spring of 2006. The flood outlook at this time is preliminary and is based on soil moisture analysis and the water content in the snow pack within the Red River watershed. Flood forecasts based upon actual runoff conditions and river flows will be issued once the spring melt actually begins.

Summary of Provincial flood outlook
A potential for moderate flooding continues to exist on the Red River. The spring flood potential is still very dependent on weather conditions from now until the end of April. A quick melt with above-average precipitation could result in serious flooding in many areas of Manitoba.

For the Red River, there is a potential for flooding due to high soil moisture and moderate snow cover in most of the watershed including the U.S. portion. Serious ice jamming appears unlikely due to below-average ice thicknesses.

With average weather, the Red River is expected to crest in Winnipeg at 19.0 feet. With unfavourable weather conditions, such as a rapid melt and an additional 50 mm plus of precipitation (1 in 10 chance) between now and the peak flow, the Red River would expect to crest at 19.5 feet James. An extreme weather event, such as a heavy snowfall or an early heavy rainfall, could result in a significant upward revision to expected flooding for this spring.

City's flood control plan
In response to this 2nd flood outlook, the Water and Waste and Public Works Departments have developed a flood control plan for a spring flood peak of 19.5 feet James. A flood of this magnitude would require the activation of 29 flood pumping stations and 173 sewer control gates as well as setting up 26 temporary pump locations. Approximately 118,000 sandbags would also be required at 48 homes within Winnipeg. The City's flood control plan will be adapted as more accurate flood forecasts become available over the next few weeks.

Rise in Red River expected to start immediately
The Red River in downtown Winnipeg is presently at 2.7 feet James. Manitoba Water Stewardship has also informed the City that the Red River is expected to rise immediately due to melting in the Fargo area a few weeks ago. It is expected that the Red River will rise to between 4.0 to 4.5 feet James over the next few days.

Preliminary flood outlook - February 27
Manitoba Water Stewardship has issued the first long range flood outlook indicating the flood potential across Manitoba for the spring of 2006. The flood outlook at this time is preliminary and is based on soil moisture analysis and the water content in the snow pack within the Red River watershed. A second flood outlook in late March is expected and will provide a better determination of the 2006 spring flood potential.

Summary of provincial flood outlook
A moderate potential for flooding exists on the Red River. The spring flood potential is still very dependent on weather conditions from now until the end of May. Below-average precipitation and an early breakup of ice would result in little or no flooding, whereas well-above-average precipitation could still result in serious flooding in many areas of Manitoba

For the Red River, there is a potential for flooding due to high soil moisture and moderate snow cover in most of the watershed including the U.S. portion. Serious ice jamming appears unlikely due to below-average ice thicknesses. With average weather, the Red River is expected to crest in Winnipeg at 18.0 feet James. With unfavourable weather conditions (1 in 10 chance) between now and May, the Red River would expect to crest at 19.0 feet James. An extreme event, such as a heavy snowfall or an early heavy rainfall, could result in a significant upward revision to expected flooding for this spring.

City's flood control plan
In preparation for the potential flood, the Water and Waste and Public Works Departments have developed a flood control plan for a spring flood peak of 19.0 feet James. A flood of this magnitude would require the activation of 28 flood pumping stations and 157 sewer control gates as well as setting up 22 temporary pump locations. Approximately 93,000 sandbags would also be required at 31 homes within Winnipeg. The City's flood control plan will be revised once a more precise flood outlook becomes available in late March.
