Niagarette River

The watershed of the Niagarette river covers an area of 53.85 square kilometres (20.79 sq mi).[2]

The Niagarette river takes its source from a small unidentified lake (altitude of 138 metres (453 ft)), located in a forest area in the eastern part of the municipality of Saint-Ubalde. This lake is located 4.8 kilometres (3.0 mi) east of the village center of Saint-Ubalde and 10.8 kilometres (6.7 mi) northwest of the confluence of the Niagarette River and the Sainte-Anne River.

From its source, the course of the Niagarette river flows over 20.3 kilometres (12.6 mi) with a drop of 108 metres (354 ft). It receives the waters of its main tributary, the Petite rivière Niagarette, at 1.6 kilometres (0.99 mi)[3] from its mouth. The average slope of the Niagarette river is 6.6 metres per kilometre (35 ft/mi). Besides the first five kilometers upstream which have a slope of 1.42%, the slope of the rest of the river is low with 3.8 metres per kilometre (20 ft/mi).

The Niagarette river flows according to the following segments:

• 1.7 kilometres (1.1 mi) to the west;
• 3.7 kilometres (2.3 mi) east to the limit of the forest area;
• 4.1 kilometres (2.5 mi) south-east to the confluence of the Rang Saint-David River (coming from the west);
• 3.5 kilometres (2.2 mi) towards the south-east, meandering in an agricultural area to the chemin du 3e rang in Saint-Thuribe;
• 3.7 kilometres (2.3 mi) towards the south-east by meandering in agricultural area to the railway bridge;
• 2.0 kilometres (1.2 mi) to the southeast by winding through an agricultural zone and cutting the route 363 until the confluence of the Petite rivière Niagarette (coming from the west);
• 1.6 kilometres (0.99 mi) to the east, forming a few loops passing south of the village of Saint-Casimir, to its mouth.

After cutting the route 354 which runs along the northwest shore of the Sainte-Anne river, the Niagarette river flows onto the shore west of the latter at 0.4 kilometres (0.25 mi) south of the village bridge of Saint-Casimir. From there, the current descends on 0.9 kilometres (0.56 mi) southwards following the course of the Sainte-Anne River, to the northwest bank of St. Lawrence River.

Agriculture covers 60% of the river basin. This is the Sainte-Anne River sub-basin whose land use is most agricultural.[4]

The majority of fish species were sampled by the Corporation d'Aménagement et de Protection de la Sainte-Anne in 2002 (CAPSA).

Two major floods have been reported in the history of the Niagarette River, in 1939[7] and in 1973,[8] On August 10, 1939, the erosion of the banks of the Niagarette river had damaged the low walls of cement and the rip-rap of the banks near the buildings south of the village of Saint-Casimir. This sudden flood also damaged the route 363 and swept away the residences of the families of Réjean Lépine and Rolland Duchesneau, located near the course of the river as well as part of their respective terrain. The houses of MM. Victorin Naud and Lévis Tessier were also damaged.[9]

On October 29, 1986, the Gazette officielle du Québec published decree 1512–86 at the request of the municipality of Saint-Casimir for the reconstruction of a dam for the purpose of aqueduct on the bed of the Niagarette river.[10]

In 1998, the municipality of Saint-Casimir had a project to divert the Niagarette river by giving it a more rectilinear route in order to resolve its flooding problems. The Niagarette river then had a meander more than 200 meters long, suitable for the formation of ice jams during the snowmelt.[11]

The spelling of the toponym occasionally took the form "Naigarette River" dating back to the end of the 19th century and perhaps even before. This toponym could be explained as being a diminutive of the famous Niagara Falls. The term Iroquois niagara means "to resonate", "to make noise".[12]

The toponym "Niagarette River" was formalized on August 17, 1978, at the Place Names Bank of the Commission de toponymie du Québec.
