Lake levels causing ground water to rise, pool - News Release #95

Tuesday, June 6, 2017 - 10:20am

Lake levels continue to trend upwards, however, from day to day, individual lake measurements may fluctuate up and down. A daily decrease in lake levels does not indicate that the flooding event has peaked.

As of Tuesday morning, Mission Creek is flowing at 30-35 cubic-metres-per-second. Rain is forecasted beginning Thursday and may persist through the weekend which could see creek flows increase again.

With lakes at unprecedented levels, the underground water table has come to the surface in some neighbourhoods. Residents should continue to monitor basements and crawlspaces in low lying areas. Local streets may close suddenly due to ground water seeping to the surface.

Residents in impacted or at-risk areas are advised to protect property to 343.5 metres plus an additional buffer for wave action. For more information about sandbagging, visit

All other Evacuation Alerts and Orders remain in effect, and residents in those areas should be prepared to leave on short notice if conditions change and there is a threat to public safety. Visit to search by address to determine if an area is under alert or order, or to find the closest sand and sandbag locations.

Residents and visitors are reminded to stay off flood protection measures. Jumping or walking on gabions or water dams is a public safety concern and could damage or undermine the device causing ruptures and significant water flows.
