Mitatut Lake is a glacial lake above the confluence of Holt Lake and Mistik Creek, approximately 21 kilometres (13 mi) northeast of Bakers Narrows. As a segment of the Mistik Creek, it is part of the Nelson River watershed, in the Hudson Bay drainage basin in the Northern Region of Manitoba, Canada. The surrounding mixed deciduous and coniferous forest is part of the Churchill River Upland portion of the Midwestern Canadian Shield forests. The region around the lake consists of rocky parallel ridges with poorly drained areas of muskeg and irregular stony shorelines due to intense glaciation. The lake is situated on the well known "Mistik Creek Loop", a remote canoe route 80 kilometres (50 mi) in length which can be paddled in four days.
