. This occurs when prevailing northerly winds blow along the length of Lake Winnipeg, exerting a horizontal stress on its surface. Surface waters move in the direction of the wind and pile up along the leeward south shores.

Furthermore, water depths are known to be extremely variable at the south end of the lake. Many of the recreational beaches on the southern end of the lake feature rustic, seasonal piers for swimmers. It is not uncommon to be able to walk off the end of one of these piers one day into more than waist-deep water, then return a few days later to the same spot to find the water only ankle deep, or even exposed sand.
