Partial sun across much of the south has given a brighter outlook to the flooding situation in Alberta.

However, some river and creek levels continue to rise and flood warnings remain in effect for the South Saskatchewan River, Willow Creek downstream of Chain Lakes, Waterton Lake, and the Waterton and Belly rivers.

Hardest hit now are residents of the Blood Reserve, where many have fled their homes as the Belly River flooded lowlands and continues to rise.

 

The South Saskatchewan is also still rising and was already up more than two metres at Medicine Hat as of Alberta Environment’s report early this morning.

Peak flow through that city is expected to be 2,800 cubic metres per second, and river levels will rise another 2.2 metres to peak mid-day Saturday.

Last year, peak flows of 5,300 cms caused flooding, so this year’s event is not expected to be as severe.

The Oldman River through Lethbridge continues to rise this morning. Levels have already risen four metres and peak flow of 2,050 cubic metres per second was expected sometime this morning.

Lethbridge County is reporting extensive overland flooding in some areas, with accompanying road washouts and standing water on cropland. The province is providing water pumps.

Flat land near Coaldale and into the Municipal District of Taber has full ditches and standing water.

All rainfall warnings have ended, and Environment Canada said no significant precipitation is expected in the next 24 hours.

Since the beginning of the major rainfall event, areas in the upper Waterton region have recorded up to 240 millimetres of rain.

Environment Canada figures indicate 150 mm in the Belly River basin, 140 mm in the St. Mary basin, 110 mm in the Willow basin, 90 mm in the Oldman basin, 145 mm in the Castle/Crowsnest and 65 mm in the Highwood.
