In 1943, the Hydro-Electric Power Commission of Ontario diverted a large part of the upper Ogoki to flow into Lake Nipigon and on to the Great Lakes. This diversion was intended to increase water flow for the Sir Adam Beck Hydroelectric Generating Stations at Niagara Falls, downstream of Lake Erie. of the Ogoki basin is diverted by a high and long dam at the Waboose Falls (also known as Waboose Rapids), constructed in 1940-43. Together with another 3 control dams, this dam raises the water level by about , thereby creating Ogoki Reservoir (which is long and covers an area of approximately ). An average of about is diverted to the headwaters of the Little Jackfish River, a tributary of Lake Nipigon, and leaving about to flow down the Ogoki River itself. This diversion increases the size of Lake Nipigon's watershed by almost 60%, and together with the Long Lake diversion of the Kenogami River, raises Lake Superior by an average of . Although the water levels have improved in the Great Lakes, it has also caused a major drop in water levels and unnatural flooding in the Ogoki River. ==Ogoki River Provincial Park==

}} The Ogoki River Provincial Park protects a long section of Ogoki River, from Ogoki Reservoir to the Thunder Bay-Cochrane boundary. It also includes Ogoki Lake in its entirety, as well as Kayedon, Harrogate, and Patience Lakes. It was established in 2004 and serves as an important recreational waterway, offering remote tourism and recreation opportunities such as angling, hunting, wildlife viewing, and backcountry canoe camping. Significant features of the park include a diversity of upland and wetland vegetation, as well as a number of glacial features. It also has a number of plant species that are of regional significance, such as the sandbar willow, along the riverbanks, and the ovate spikerush, found on an Ogoki Lake beach. It is a non-operating park, meaning that there are no facilities or services. Permitted activities include boating, canoeing, fishing, and hunting. ==See also==
