With rivers running high, it is a good day to keep travel plans from going downstream.

The Sheep River and Highwood River remained under a high streamflow advisory Tuesday morning as heavy rain continued in the region.

Preliminary data from Rivers Alberta showed elevated flows at local monitoring stations:

• At 6:30 a.m., the Sheep River at Okotoks was flowing at 120.69 cubic metres per second, with a water level of 27.5 metres.
• At 6:05 a.m., the Highwood River at High River was flowing at 158 cubic metres per second, with a water level of 2.77 metres.

Alberta River Basins says its online data is provisional and preliminary. The information is automatically generated by remote equipment, may not have been reviewed for accuracy, and can change after review or correction.

Environment Canada reported that 40 to 120 millimetres of rain had fallen across the region since Saturday evening, with some parts of southwestern Alberta receiving up to 135 millimetres. Another five to 10 millimetres of rain was expected Tuesday.

Water could pool on roads and in low-lying areas, and utility outages were possible. Drivers were advised to avoid flooded roads and watch for washouts near rivers, creeks and culverts.

Local officials are keeping a current watch on river conditions.

The Sheep River and Highwood River remained under a high streamflow advisory Monday afternoon as communities monitored conditions during significant rainfall.

Preliminary data from Alberta River Basins reported:

• The Sheep River at Okotoks was flowing at 38.04 cubic metres per second at 2:30 p.m., with a water level of 26.77 metres.
• The Highwood River at High River was flowing at 85.9 cubic metres per second at 1:05 p.m., with a water level of 2.14 metres.

River basin readings are automatically collected by remote equipment and have not been reviewed for accuracy. The figures may change after corrections.

Diamond Valley reported at 2 p.m. that repairs to the Black Diamond river monitoring station were expected by the end of the day. Diamond Valley Emergency Management said crews were using field observations and other data sources while the station remained offline.

The agency had not identified river flooding concerns. It said continued rain could still cause water pooling, overloaded drainage systems and minor overland flooding in low-lying areas.

A yellow-level wind warning was also expected to remain in effect Monday evening, with gusts of up to 90 km/h. Saturated ground could increase the risk of falling trees, utility outages and property damage.

Conditions were forecast to ease within 24 hours. Diamond Valley Emergency Management said further updates would be issued if needed.
