River Levels

Northwest Territories river levels

Live streamflow at 50 gauged Northwest Territories rivers, highest first. Where a gauge has a long enough record, the reading is placed against its own history for today's date.

39% of gauged Northwest Territories rivers are running above normal for the date, as of October 27, 2026.

Of 44 gauged rivers with a long enough Water Survey of Canada record, 14 are below normal (6 of them much below), 13 are in the normal range, and 17 are above normal (12 of them much above). Normal means the middle half of that gauge's own history for this calendar date.

Streamflow from the Water Survey of Canada (Environment and Climate Change Canada), Open Government Licence - Canada, read every six hours. "Usually today" is the median for this calendar date, which we compute from the gauge's own daily record (HYDAT). A gauge tells you how much water is moving, not whether a stretch is safe to run: check the channel, the hazards and a current local notice before you launch.
