Known also as Nipawi, Nepiwa, Neepoin, Nippewean, Nepowewin and Fort Des Prairies or Aux Trembles.

Old French fort on south side of Saskatchewan river, about 100 miles above The Pas, just below the Nipawin rapids and about 3 miles below the Cadotte rapids. Built about 1748. This fort is mentioned by Sir A. McKenzie who calls it Nepawi House. It was regularly operated by the French until the cession of Canada and was abandoned about 1763. After the French, the first English trader to reach the locality was James Finlay who in 1767 either occupied the old French fort or constructed Finlay's House (q.v.) nearly opposite on the north bank. Finlay wintered there in 1771-72, also 1775-76, and Cadotte of the Hudson's Bay Co. and A. Henry Sr. were there in 1776, and Thompson in 1808. After the formation of the North West Co. in 1783, the old French fort was occupied by that Company and it was called "Nepoin" fort. Porter and McLeod of the North West Co. were in charge in 1794. About 1808 the Company abandoned the old fort. A. Henry Jr. passed "the old establishment at the Nepawee" on August 30, 1808, apparently deserted. The old French fort is shown on Franklin's map and the North West Co. "Nepoin" on Thompson's map 1812 (No. 7). Fort à la Corne (St. Louis) was known as Upper Nipawi and Nepoin as Lower Nipawi. Location of the Nipawin rapids is shown on maps No. 37 & 42, and the old fort on maps No. 3, 10, 12.
