Hudson's Bay Co. post originally built about 1872 at junction of Mattawa and English rivers, Ontario, (outlet of Pakwash or Shallow lake) on north bank, see maps No. 79 and 57. A small Indian village was located nearby. About 1923 this post was moved about [60] miles to the east near the east end of Lac Seul at Pine Ridge on the north shore and the name was changed to Pine Ridge Post (Maps No. 138 & 79). See Fort Lac Seul. Fort Mattawa was apparently an outpost of Fort Lac Seul and later was combined with it, Lac Seul having been established 1815.
