NWT Water Monitoring Bulletin – May 25, 2022

News Type: 
Water monitoring bulletin

The Government of the Northwest Territories maintains water monitoring stations across the territory to keep track of water levels and flow rates in areas of potential flood risk for communities.

This information is provided regularly to territorial and regional emergency managers to help understand the status of waterways across the NWT in the lead-up to, and during spring break-up – the highest-risk period for floods in the Northwest Territories.

Technical data

 

Current status - NWT

  • The ice jam on the Mackenzie River appears to have released at Tsiigehtchic, and the head (upstream end) of the ice jam is now at Point Separation;

    • Ice and water from the large jam are expected to have moved downstream and into the Delta;

    • Although hydrometric data are still unavailable at the Mackenzie River at Arctic Red River gauge, there are reports of water levels having receded at the ferry crossing;

    • We will be monitoring gauges, photos, and satellite imagery to track the progression of the ice front.

  • Water levels under ice continue to increase in the Mackenzie River Delta, at normal rates for this time of year;

    • Water levels at Aklavik are at 13.7 m (maximum from last year was 15.539 m).

    • Water levels at Inuvik are 15.0 m (maximum from last year was 15.561 m).

  • Water levels on the Peel River at Fort McPherson are slowly dropping and appear to have reached their ice-induced peak after rising on the weekend.
