River course
The origin of the Bonaparte River is the small mountain lake Couture Lake . This is located at an altitude of 1500 m on the Bonaparte Plateau , an eastern part of the Interior Plateau . The source area, rich in lakes, is partly within the Bonaparte Provincial Park . The Bonaparte River initially flows north 15 km and flows into the eastern end of Bonaparte Lake . The Bonaparte River leaves the 17 km long lake at its western end. Then it flows 15 km to the northwest. The Machete Creek flows into the Bonaparte River on the right. This now turns to the southwest. It flows through Young Lake , which is a river widening, and then flows west. Later, for the last 60 km, the Bonaparte River turns south. It passes the Cache Creek settlement and finally flows into the Thompson River, which flows south-southwest, above the small community of Ashcroft . The middle course of the Bonaparte River forms the boundary between the Bonaparte Plateau and the Cariboo Plateau to the north .
Hydrology
The mean discharge at the gauge 11 km above the mouth is 5.8 m³ / s. The catchment area covers around 5050 km². The months of May and June are usually the most draining months.
