The Incomappleux River is a 67 km long river in the eastern part of the Canadian province of British Columbia .
The headwaters of the Incomappleux River is on the southwest flank of the Sir Donald Range in the Selkirk Mountains . There the river is fed by the Geikie glacier at an altitude of about 1600 m . The Incomappleux River initially flows 10 km towards the west-southwest, later in a southerly direction through the mountains before it flows into the 440 m high Upper Arrow Lake . The top 10 miles of the Incomappleux River is within Glacier National Park .
Hydrology
Since the completion of the Hugh Keenleyside Dam on the Columbia River in 1968 and its damming up to the Arrow Lakes , the Incomappleux River no longer flows directly into the Columbia River, but into the Beaton Arm , an eastern side bay of Upper Arrow Lake . The damming shortened the course of the river by around 17 km. The catchment area of the Incomappleux River covers an area of 1020 km². The mean discharge 4.5 km above the mouth is 55.8 m³ / s. The highest runoffs usually occur between May and August.
