“Located in southeastern Manitoba, the Seine River Watershed is approximately 2,509 square kilometres in size. The Seine River has its headwaters in the Sandilands Provincial Forest, near the village of Marchand. The river meanders northwest to the town of Ste. Anne where the Seine River Diversion channels a portion of the flow west to the Red River. Between Ste. Anne and the Red River, the Diversion is joined by a number of tributaries, including Youville, Drain, Manning Canal and St. Adolphe Coulee. From Ste. Anne, the Seine River continues northwest, passing under the Red River Floodway through the Seine River Siphon and joins the Red River in Winnipeg.”
