A new forecast from Saskatchewan has somewhat lowered the water levels expected on the Saskatchewan River in The Pas. Dikes will still need to be raised on Ralls Island, but not as high as the four additional feet anticipated yesterday. Water levels are expected to reach 855.5 to 857 feet, depending on the weather. Preparations to reinforce existing dikes and build permanent dikes are underway.
The wind warning for the Lake Manitoba area has been lifted. A strong wind warning is in effect for Lake Winnipeg’s North Basin. Winds at Dauphin Lake are forecast to be northwest 20 km/h today, then veer southwest tomorrow.
Peak lake level forecasts have increased as a result of the heavy rains from the recent storm. Lake Manitoba is forecast to peak at 816.3 to 816.5 ft. around July 5, depending on weather. Lake St. Martin is expected to be 805.3 to 805.6 ft. around July 25. On Lake Pineimuta, the peak is expected to be between 808.5 and 808.8 ft.
