Flooding in Pitt Meadows is largely determined by what is happening in the Cariboo region coming through Prince George via the Fraser River. Flooding will typically show up in Mission first.

Flood response planning is based on the Fraser River levels in Mission measured by the Mission gauge.

Current Flood Status

May 21, 2020: The City is currently monitoring river levels (PHASE 1 below). No active flooding.

River Levels and Flood Response

The City of Pitt Meadows has a detailed flood response plan based on river levels measured by the Mission gauge (see below for more information).

 

                                    FRESHET FLOOD RESPONSE LEVELS

 
 
 
 
 

PHASE 1: Mission 1.0 to 5.0 (Below bank conditions)

  • River level is normal

What the City’s Doing

  • Day to day operations
  • Reviewing Freshet Plan and flood supplies
  • Inspecting dikes weekly and other flood protection infrastructure
  • Monitoring Mission Gauge and weather forecast

What You Can Do

PHASE 2: Mission 5.0 to 6.0, Hope 11,000 m3/s+ (Flood preparedness)

  • Rising river level has filled its natural banks, but has not spilled over into the floodplain
  • Localized flooding may be present

What the City’s Doing

  • Inspecting dikes regularly
  • Continuing planning activities

What You Can Do

  • Monitor the City’s website and social media channels or local media for updates about sandbagging stations or possible evacuation procedures or routes.
  • If a flood warning is in effect, shut off electricity to areas that are at risk of flooding and move small appliances, electronics and smaller furniture to upper floors or areas not likely to be affected.
  • Make sure your grab-and-go bag is ready, if you need to evacuate.

PHASE 3, Stage 1: Mission 6.0+ (Flood response)

  • Emergency Operations Centre (EOC) activated to Level 1 or 2
  • Local State of Emergency may be declared
  • River banks are full; flooding anticipated
  • Possible flood alerts

What the City’s Doing

  • Inspecting dikes more frequently
  • Monitoring and preparing for flood response

What You Can Do

  • If an evacuation alert has been issued, be ready to leave on short notice.
    • Gather your grab-and-go bags, emergency plan and important documents.
    • Ensure your vehicle has fuel and is parked away from waterways.
    • Do NOT attempt to shut off electricity if water is present.
    • Use sandbags to block floor drains and toilets to prevent sewage back-up.

PHASE 3, Stage 2: Mission 7.0+ (Flood response)

  • Emergency Operations Centre (EOC) activated to Level 3
  • Possible flood evacuation order
  • Provincial State of Emergency may be declared
  • Possible river widening into floodplain adjacent to the dikes

  • Follow instructions from officials and evacuate using designated routes.
    • Do not attempt to cross rivers or flowing streams.
    • Do not drive or walk across flooded roads: Two feet of water can carry away most vehicles and six inches of fast-moving water can knock an adult off their feet.
    • If your car begins to flood, abandon it and head to higher ground.

PHASE 3, Stage 3: Mission decreasing (Demobilization and recovery)

  • Emergency Operations Centre (EOC) activation levels reduced
  • Flooding receding

What the City’s Doing
