A water management plan (WMP) has been prepared for the Namewaminikan River – High Falls Generating Facility. The High Falls Generating Facility is situated on the Namewaminikan River approximately 10 km northwest of Beardmore, in Sarnia Township and has a nameplate capacity of 5.3 MW. The zone of influence included in the WMP extends approximately 5 km from 1 km below High Falls upstream to the lower end of Long Rapids. The WMP will address the management of in-stream flows and levels in the river as they are affected by the operation of waterpower/water control projects owned by The Power Limited Partnership (TPLP) by its general partner Nipigon General Partner Inc.
The Namewaminikan River watershed drains an area of approximately 2,500 km2. The headwater of the Namewaminikan River is the area around Barbara Lake at the southern end of the watershed. From there, the river takes an irregular meandering northeast course through a series of lakes to Turkey Lake. It outlets at the northwest side of Turkey Lake and continues westerly to Elmhirst Township, where it turns southwest towards the High Falls Generating Station. Beyond the Generating Station, the river flows mainly west to Lake Nipigon.
The river supports a range of aquatic ecosystems and human uses, including canoeing, and fishing.
The WMP was developed by a planning team having representation from The Power Limited Partnership, MNRF and First Nation representatives from Animbiigoo Zaagi’igan Anishinaabek, Biijintiwaabek Zaaging Anishinaabek, Bingwi Neyaashi Anishinaabek, Poplar Point Ojibway Nation, and Red Rock Indian Band. A steering committee, comprised of representatives of the above dam owner, agencies and First Nations, will provide direction to the planning team.
