State of local emergency declared for properties on the river side of primary dike
Declaration enables City to respond quickly to changing flood conditions
The City of Winnipeg has declared a State of Local Emergency covering all properties on the river side of the primary dike, as of 11:13 a.m., Thursday, April 16, 2009. This declaration is authorized under the Province of Manitoba's Emergency Measures Act, and has been made to allow the City to respond quickly to an evolving flood situation.
"This activation gives us the ability to respond rapidly and decisively to changing conditions," said Mayor Katz. "It is not a cause for citizens to be anxious; it simply enables our flood-fighting team to respond quickly should localized issues develop."
Randy Hull, the City's Emergency Preparedness Coordinator, explained that this activation enables the City to respond without delay in areas of concern. "So far, our flood-fighting efforts are going well, but this is obviously a major flood event – and we need to be able to act quickly."
Residents of Winnipeg along the river side of the primary dike are asked to cooperate with Police, Fire, Paramedic personnel and other City officials for the duration of the emergency. Your cooperation with will greatly assist in the flood-fighting effort.
The State of Local Emergency is in effect until April 29, 2009.
Summary of Provincial flood forecast for the Winnipeg area
The Red River is currently at 17.3 feet James Avenue datum. For the next few days, levels will only increase between 1 to 2 tenths of a foot per day. A peak of 19.0 to 20.5 James is forecast to occur on the Red River in Winnipeg between April 8–17. The Province has indicated that the risk of a serious ice jam this year is greater than usual. Ice jams can cause a rapid and unpredictable increase in local water levels.
City's flood control plan
The City of Winnipeg is preparing for peak water levels forecast by the Province with a freeboard allowance of three feet throughout the City except for the Kingston Crescent area and areas south of the South Perimeter Highway. These areas are historically more prone to ice jamming and a four foot freeboard allowance will be used in preparations. As levels rise, flood pumping stations, temporary pumps and flood control gates will be operated as required. The City is also raising some low areas on the primary dike.
City crews are continuing to notify at-risk property owners as well as to survey and stake these properties. City employees have approached at-risk property owners to determine residents' needs for assistance in building or raising sandbag dikes. As a result, the City has activated the volunteer component of its emergency plan.
The City of Winnipeg is still producing additional sandbags. Sandbags will be delivered to impacted properties to enable those at-risk property owners to build sandbag dikes to the required levels.
Residents requiring sandbags to manage local drainage concerns may pick them up from any of the three distribution centres located across the city.
External agencies potentially affected by the high water have been advised to initiate private flood control measures.
Summary of Provincial flood forecast for the Winnipeg area
Currently the river is at 16.7 feet James. A peak of 20.5 James Avenue datum could occur on the Red River in Winnipeg as early as Friday, April 3 if the ice has not moved out of the city and the Floodway is not yet operational. The Province has indicated that ice jams are possible within the city. Ice jams can cause a rapid and unpredictable increase in local water levels.
City's flood control plan
The City of Winnipeg continues to prepare for a water level of 20.5 feet James. For that level, 33 flood pumping stations will be activated and about 220 flood control gates will be operational. There will be about 35 temporary pumps deployed. The City is also raising some low areas on the primary dike.
An ice cover currently exists on the river within Winnipeg. When this ice begins to move, there is the potential of an ice jam developing that would cause river levels to rise very quickly. Accordingly, the City is notifying all at-risk homeowners to increase their dikes by about one foot.
City crews will survey and stake those properties to the new required dike level. Based on the current flood forecasts, the number of properties at risk within the City is approximately 80.
The City of Winnipeg is working to produce additional bags. Sandbags will be delivered to impacted properties to enable those at-risk property owners to build sandbag dikes to the new levels. External agencies potentially affected by the high water have been advised to initiate private flood control measures.
Residents requiring sandbags to manage local drainage concerns may pick them up from any of the three distribution centres located across the city.
Summary of Provincial flood forecast for the Winnipeg area
Spring runoff is well underway in the Red River watershed. The Red has risen rapidly and will continue to rise rapidly until the ice clears from the Floodway Inlet. Ice is expected to clear tomorrow or Friday. The water is expected to peak at about 20 feet James Avenue datum before the ice clears. Currently the river is at 16.7 feet James.
A second peak on the Red River for an open water condition is expected from April 12 - 17. The crest on the Red is expected to be between 19.0 and 20.5 feet James at that time.
City's flood control plan
In preparation for the immediate potential flood peak expected tomorrow or Friday, the Water and Waste and Public Works Departments are enacting a flood control plan for a level of 20.0 feet James in the downtown and north areas of the City and 21 feet James in the south areas of the City where the potential for ice effects are the greatest. A flood of this magnitude will require the activation of 31 flood pumping stations and 200 sewer control gates as well as setting up 33 temporary pump locations. City crews have been surveying and staking the 34 properties at risk. It's estimated that 24,000 sandbags will be required for these properties.
Residents requiring sandbags to manage local drainage concerns may pick them up from any of the three distribution centres located across the city. External agencies potentially affected by the high water have been advised to initiate private flood control measures.
Second flood outlook - March 17
Summary of provincial flood outlook for the Winnipeg area
A potential exists for very high river levels to occur this spring on the Red River in Winnipeg. Manitoba Water Stewardship stated that the:
"March 10 blizzard in the US portion of the Red River watershed was significant due to the high soil moisture conditions and above average snow cover which already existed in the US prior to the storm."The peak Red River level is still very dependent on weather conditions from now through to spring.
With average weather, the Red River is expected to crest in Winnipeg at 19.5 feet James Avenue datum. With unfavourable weather conditions (1 in 10 chance) between now and spring, the Red River would be expected to crest at 22.2 feet James.
City's flood control plan
In preparation for the potential flood, the Water and Waste and Public Works departments will develop a flood control plan for a spring flood peak of 22.2 feet James. A flood of this magnitude would require the activation of 33 flood pumping stations and 223 sewer control gates as well as setting up 41 temporary pump locations. Sandbagging at 292 homes within Winnipeg would also be required at this high level to protect from river flooding. The departments will ramp up flood preparations as the spring event progresses. Properties requiring sandbags will be notified as required. As in past years, stockpiled sandbags at selected sites will also be available for the public to pick up to protect their homes from overland flooding.
The City's flood control plan will be based on the Spring Flood Outlook. The actual event will be influenced by highly variable factors and as such the City's plan will be revised as more precise flood forecasts become available.
Preliminary flood outlook - February 19
Manitoba Water Stewardship has issued the first long range flood outlook indicating the flood potential across Manitoba for the spring of 2009. 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 2009 spring flood potential.
Summary of provincial flood outlook for the Winnipeg area
An above average potential for high river levels exists on the Red River in Winnipeg. Manitoba Water Stewardship indicates that the soil moisture content in the Red River Valley is at near record levels. Wet frozen soils impede infiltration of melt water and increase spring runoff. The moisture content of the snow pack is about average in Manitoba and above average in the U.S. portion of the Valley. However, the potential for flooding is still very dependent on weather conditions from now through to spring.
With average weather, the Red River is expected to crest in Winnipeg at 19.0 feet James Avenue datum. With unfavourable weather conditions (1 in 10 chance) between now and spring, the Red River would be expected to crest at 20.0 feet James.
City's flood control plan
In preparation for the potential flood, the Water and Waste and Public Works Departments will develop a flood control plan for a spring flood peak of 20.0 feet James. A flood of this magnitude would require the activation of 32 flood pumping stations and 201 sewer control gates as well as setting up 35 temporary pump locations. Sandbagging, to protect from river flooding, at a limited number of homes within Winnipeg would also be required. As in past years, stockpiled sandbags at selected sites will also be available for the public to pick up to protect their homes from overland flooding.
The City's flood control plan is based on the February preliminary flood outlook. The actual event will be influenced by highly variable factors and as such the City's plan will be revised as more precise flood forecasts become available.
