NWT Water Monitoring Bulletin – April 25, 2023

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

  • Snowmelt, river ice melt, and small rises in water levels continue in southern basins in the NWT.
  • On the Hay River in the NWT, river ice is beginning to shift but remains largely intact and water levels continue to rise slowly.
  • The initiation of spring break up and water level rise in the Hay River is earlier than normal due to warm spring temperatures
  • Small amounts of rain and snow are forecasted in the Hay River basin over the next 24 hours, which would encourage continued melting of snow and river ice.

Current status - Hay River

  • Snow in the upper (southern) part of the basin continues to melt;
  • Water levels have begun to rise at the downstream (northern) gauges, but the rate of increase is still small and normal for the onset of freshet;
  • The onset of water level rise is occurring earlier than normal and much earlier than last year;
  • Small amounts of rain and snow are forecasted in the Hay River basin over the next 24 hours, which would encourage continued melting of snow and river ice;
  • Ice is degrading along the Hay River within the NWT, with some open patches of water beginning to appear;
  • Refer to the Town of Hay River website for the most up-to-date information, as well as webcam images of current conditions.
