River Breakup

What is river breakup?

During the spring months, there is an increased risk of flooding when ice on the Athabasca, Clearwater and Christina rivers begins to melt and break apart. Stay informed with information on ice forecasting and warning and ice jam flooding.

River breakup preparedness

Residents may see a number of temporary measures installed in the downtown area, including triple dams (water filled barriers), temporary clay berms, pumps and plugs. There will be temporary road closures and temporary trail closures to allow for these measures. 

  •  Be aware and stay informed
  • Watch out for thin ice and stay away from riverbanks 
  • Tune into the Alberta Environment website for real-time advisories and warnings
  • Listen to local media
  • Tune into this website, Twitter or Facebook
  • Arrange with neighbours to advise one another of an emergency notification
  • Make an emergency plan for your household
  • Prepare an emergency kit for your household
  • Learn the river breakup evacuation zones
  • Review your insurance policy and check to ensure you have overland and sewer backup flooding insurance
  • Take a video with the date displayed of your belongings
  • Install backflow valves in sump pumps, the floor, sink, toilet, and washing machine drains in your basement to prevent sewer backups. There is a Backwater Valve Grant program available. 
  • Install weather protection sealants around basement windows and ground-level doors
  • Check sump pumps to check they are working
  • Landscape and build-up areas against your foundation to keep water moving away. There are free sandbag materials available. 
  • Confirm downspouts are at least six feet away from your basement wall and are working (check to ensure the water does not drain onto your neighbour's property)
  • If your property is next to a ditch or stream, keep the banks clear of brush and other debris
  • Store valuable items on the upper floors of your home, away from the basement
  • If flooding is close, shut off electricity and put up barrier for basement windows and doors
  • Clear snow away from your home's foundation

Sand and bags are available free of charge to residents and business owners.

While there is no firm limit on the number that can be taken, the intended use of the sandbags is to place them around doors, windows and other openings to provide additional flood protection for private properties.

New location

  • Location: RMWB Satellite Yard - 28 Silin Forest Road - The area is fenced and gated, so please call Pulse to arrange a time and staff will open the security gate. Access will be made available on weekdays and weekends until River Breakup is complete.
  • These sandbags are intended to provide additional flood protection for homes and businesses.

  •  Please…

    • Take only what you need
    • Bring your own shovel
    • Secure your own transportation to and from the site, including transportation of sandbags
    • Properly secure all loads
    • Do not litter

Community members can keep, and reuse filled sandbags in the future, but they must be stored properly to prevent damage. Sandbags can be stored inside or outside but they must be protected from the sun, rain and snow. If storing outside, it’s recommended to place sandbags on a pallet and cover them with a waterproof and UV resistant tarp.  

  • Information on sandbag disposal will be provided after river breakup. 

  • Follow evacuation instructions
  • Do not walk through moving water or standing water
  • Do not drive through flooded areas
  • If your vehicle stalls in rising waters, all passengers should get out and go to higher ground
  • Stay away from flood zones and response route
  • In the event of a flood, residents may be evacuated, make sure you know which zone you live in by using the evacuation zone map.

 Returning to your property

  • If utilities were shut off during the flood, you are required to follow the RMWB's restoration plan and instructions provided at the time of re-entry before returning to your property.  
  • Review Alberta Health Service's "Returning to your home after a flood" safety information 
  • Exercise extreme caution when you return to your home or business
  • Do not enter any building unless it is structurally sound

 

If your property was damaged: 

  • Avoid damaged areas or areas that contain dangerous debris
  • Do not enter areas with standing water due to hidden hazards
  • Do not handle items that have touched floodwaters unless you have personal protection equipment (PPE) and wash your hands properly after removing gloves. Floodwaters carry microorganisms from the river and may contain sewage and chemicals
  • Get an electrical panel and appliance inspection by a qualified technician before having your utilities reconnected
  • Before drinking the tap water check for odd colours or odours

Completing a damage assessment

  • Follow the RMWB's restoration plan and instructions provided at the time of re-entry. 
  • Take a video to record any flood damage to your property
  • Store any valuable papers in the freezer, do not discard any papers damaged during the flood
  • Watch for information on disaster recovery programs

Cleaning your property

  • Review Alberta Health Service's "Cleaning a house after a flood" information package. 
  • Arrange for childcare while you clean to cut your child's exposure to contaminated areas
  • Do not bring pets back until it is safe

How river breakup happens

During the spring months when the flooding risk is greater, our Emergency Management branch works with Alberta Environment to mitigate the flood risk.

  • There are many checkpoints on the Clearwater River to provide warning of an ice break.
  • The type of breakup (thermal or dynamic) is dependent on weather and river conditions.

Thermal breakup

Thermal processes melt the ice cover and weaken it (picture an ice cube disappearing in a glass of water as it melts). Contributing factors include sunshine or wind, increased water or air temperature.

Dynamic breakup

Dynamic processes push the ice cover out of its original place and into chunks. These chunks are then pushed downstream. Precipitation, water levels, or water movement that causes the ice cover to break before it has weakened.

Dynamic breakup is more likely to cause an ice jam and create a higher flood risk.
