Editing Lake Manitoba (section)

=== Flood in 2011 ===
Due to above average snowfall over the winter of 2010–2011, and above average precipitation in the spring over the Lake Manitoba watershed, forecasted water levels on Lake Manitoba called for levels above the regulated upper range of {{convert|812.5|ft|order=flip|abbr=on}} above sea level and around the flood stage of {{convert|814|ft|order=flip|abbr=on}} above sea level. With the added inflows of the [[Portage Diversion]] due to high water levels on the [[Assiniboine River]] and its tributaries, of up to {{convert|34,000|cuft/s|m3/s|order=flip|abbr=on}} of water the lake peaked at {{convert|817.2|ft|order=flip|abbr=on}} above sea level on July 21.<ref>Water Survey Canada</ref> On May 31, 2011, when the lake was already very high, {{convert|815.13|ft|order=flip|abbr=on}}, strong winds from the north and the north-west of {{convert|70|km/h|abbr=on}} gusting to {{cvt|90|km/h}} caused major damage to beaches and communities on the south basin of the lake including [[Twin Lakes Beach, Manitoba|Twin Lakes Beach]], [[St. Laurent, Manitoba|St. Laurent]], St. Ambroise, Delta Beach, Lynch Point, Big Point, and large areas of farmland.
