The City of Lethbridge remains under a flood watch, and officials have gathered at the Emergency Operations Centre to plan a course of action in light of all the rain that is in the forecast.

The Oldman River is expected to peak late tomorrow or early Thursday. Bridge Valley Campground has been asked to evacuate by noon on Wednesday.

Emergency officials have issued a flood warning for the entire Oldman River basin in southern Alberta.

The warning issued Tuesday afternoon covers several rivers, creeks and a lake.

- Castle River.

- Crowsnest River.

- Oldman River upstream of Oldman Dam.

- Willow Creek downstream of Chain Lakes.

- Waterton River.

- Belly River.

- St. Mary River.

- Oldman River downstream of the Oldman Dam.

- Waterton Lake.

- Lee Creek.

- Pincher Creek.

Officials are urging people to be cautious of rising water levels and to take appropriate precautionary measures to avoid flood damage.

Rainfall warnings are still in effect for areas in the south of the province, but do not include Calgary. 

High River residents, badly hit by flooding a year ago, have been anxiously watching the water.

On Tuesday morning, town officials said forecasters are expecting a total of 70 millimetres of rain by Wednesday evening, which would result in a 1.2-metre rise in river levels with a 215 m³/s flow rate.

"With this flow rate it is only the neighbourhood of Wallaceville that is in any danger of seeing low level flooding – and Wallaceville area residents have been notified accordingly. The rest of the town is protected by berms, dikes and other flood mitigation methods to at least 1200 m³/s," officials said in a press release.
