Tama Koshi

The river Tama Koshi flows down from Tibet and has a volume twice that of the bhote Koshi. After flowing 75km down, it reaches the road at Busti which is the usual put-in point. 'Tama Koshi' in Nepal means 'River of Copper'. The river is recommended only for keen Kayakers who can maeuver through the treacherous waters. The put-in point is at Busti Bridge which is reached after a 4-hour drive by car from Kathmandu.

The river deceptively is quite calm on the outset, but soon plenty of rapids are encountered for the next 4km before an island is reached. Both sides of the island present Class V + rapids.
Then for 5km, a continuous series of Class IV + rapids lead to bigger Class V rapids. This is once more followed by class IV rapids that continue until the confluence with Khimti Khola is reached. The big rapid that comes up next is 'Fatal Attraction' and a portage is called for. The river then gets tamer until at Chisapani, it is Class III. Going further down for another 4km the Akase airstrip is reached. The Sum Koshi is 1km from here.
