Boundary Watershed Update
April 24, 2026
Boundary watershed update
As many have seen, snowpack is lower than normal in the Boundary region. The southern monitoring stations at Gold Axe Camp and Sentinel Butte have melted, while Grano is at about 67% of normal for this time of year. Modelled snow estimates show remaining snow in the higher elevations, mostly northern half and east of the watershed (images below). Less snow than last year this time, but more than we had in 2015 (April snow level percentages shown between 2010-2026).
Main river levels in the Boundary region typically peak in the third to fourth week of May. With more than a month still to go, a typical freshet may be harder to achieve if spring stays warm and dry, while a cool and wet spring could still result in more normal conditions.
Over the past month (March 15 to April 13), precipitation ranged from 18 mm in Rock Creek to 94 mm in the northern part of the watershed. Even so, AAFC identified the Boundary as drier than normal over the past 90 and 180 days.
Following a wetter fall, many aquifers were able to recharge from the drier summer, and those located near water bodies are still showing normal water levels for this time of year.
The next several weeks will be important. Continued warm, dry weather could lead to lower water levels earlier in the season, while cooler, wetter weather would help support more typical conditions.
Now is a good time to prepare by:
-fix water leaks, stop dripping taps and running toilets
-add mulch to gardens- reduce evaporation from the soil
-plant drought-tolerant species
-setting up drip irrigation where possible, plan to reduce overhead sprinklers
Overall, look for ways to reduce unnecessary water use at home, in the garden, and at work. Planning ahead now can help us all be WaterWise and FireSmart this season.
