Bonnechere River

The Bonnechere River begins in Algonquin Provincial Park at McKaskill Lake in geographic Clancy Township in the Unorganized South Part of Nipissing District.[2] It heads north into geographic Niven Township, then loops back southeast into Clancy Township, under a Hydro One transmission corridor and into geographic Guthrie Township. It continues southeast through the Crooked Chute, over the High Falls, through the Stacks Rapids to the unincorporated place Basin Depot, located on a former logging road. The river continues southeast out of the park at Boundary access point (Access point Q), enters geographic Burns Township in Madawaska Valley, Renfrew County, then heads into geographic Richards Township in Killaloe, Hagarty and Richards, Renfrew County, takes in the left tributary Pine River, passes through the Jack Chute Rapids, and reaches Round Lake, where it takes in the right tributary Sherwood River. The rivers leaves the lake at Grassy Bay controlled by the Round Lake Dam and reaches Golden Lake in North Algona Wilberforce, where it is crossed by Ontario Highway 60. The lake is home to Killaloe at the west and the Algonquins of Pikwàkanagàn First Nation at the southeast. From Golden Lake until the river reaches Admaston/Bromley downstream, the river forms the boundary between North Algona Wilberforce (left bank, on the north) and Bonnechere Valley (right bank, on the south). The Bonnechere River leaves Golden Lake controlled by the Golden Lake Dam.

The river reaches its mouth at Lac des Chats on the Ottawa River near the settlement of Fergusons Beach.

The river is 145 kilometres (90 mi) long and drains an area of 2,400 square kilometres (927 sq mi).

During the 19th century, the river was used to transport white pine logs from the forested areas surrounding the river. A number of hydroelectric plants have been built on the river.

The Bonnechère Caves, formed from ancient limestone, are located by the river near the village of Eganville, Ontario, in the hamlet of Fourth Chute, Ontario.[3]

The First Chute (waterfall) of the river is where the Bonnechere empties into the Ottawa River, at Castleford. The Second Chute is in Renfrew; this waterfall has a small hydroelectric dam. The Third Chute is in Douglas, Ontario; it also has a small hydroelectric dam. The Fourth Chute is in the small village Fourth Chute, and the Fifth Chute is in Eganville, Ontario.

There are two provincial parks along its length: the Bonnechere River Provincial Park (a 23 km long section bordering Algonquin Park) and the Bonnechere Provincial Park (located on Round Lake).

The Bonnechere River lies mostly in a 175 million year old rift valley called the Ottawa-Bonnechere Graben.

Over the years, songs have been written about the Bonnechere River including the recent "In The Arms Of The Bonnechere River" by Ottawa Valley singer/songwriter, Terry McLeish.

Each year the river is host to a raft run between the third and fourth chute. Originally arranged by local Shriners the run has taken on a less official status, occurring with little to no organization apart from its pre-determined date during Victoria Day weekend. Participants design and build a raft or anything else they hope will take them down the river. The river presents natural obstacles in the form of light rapids. There is no competitive angle to the run with no prize at the end other than warmth and a good time. Most participants are young adults from the area returning to visit friends and family. Having recently surpassed its twenty-fourth year, the river run is a local tradition.
