Much of the Saskatchewan River Delta, a large inland delta that straddles the Canadian provinces of Saskatchewan and Manitoba, istoo wetfor extensive farming.
But amid the delta’s winding channels, lakes, and marshes, an “island” of straight-edged fields breaks up the curvy contours.
These fields, west of the town of The Pas, make up Manitoba’snorthernmost agricultural area.
Known as the Carrot River Valley, the area lies within the Rural Municipality of Kelsey.
Its actively farmed land spans more than 40,000 hectares between the Carrot and Pasquia rivers—tributaries of the Saskatchewan River—and is surrounded by wetlands, including the marshes of the Saskeram Wildlife Management Area to the north.
These images show the valley at two points during the 2026 growing season: on July 2 and September 21.
They were acquired with theOLI on the NASA-USGSLandsat 9andLandsat 8satellites, respectively.
Landsat data feed into the Agriculture and Agri-Food Canadaannual crop inventory.
The 2026 inventory was not released as of late September, but the 2025 map shows that farmers in the Carrot River Valley grew mostly canola and spring wheat that year, along with small patches ofCanary seed.
The July 2026 image shows green crops across many of the valley’s fields.
Planting in the area, part of Manitoba Agriculture’s Northwestcrop reporting region, began later than in parts of the region to the south because ofwet conditions.
Still, fertile soils and long summer days at this northern latitude can help crops grow quickly.
By the time of the September image, the patternhad flipped.
The Pas recorded little rainfall in the preceding week, while wetter weather elsewhere in the Northwest region held up the harvest.
By then, farmers across the region had harvested about 10 percent of the canola and 50 percent of the spring wheat.
Managing water has long been a challenge in the valley.
In the 1950s, a majorflood control and drainage projectgot underway, and farming in the area today still depends ondiking and pumpingfor agricultural flood protection.
