Nam Ko Dam Oudomxay Hydropower Info by Hobo Maps - Go to Hydropower Projects Page - - - HOME

This Nam Ko Dam hydropower project is located in La district, Oudomxay Province of northern Lao PDR.

There is another Nam Ko reservoir in Xieng Khouang Province and our separate web page for this other project is at Nam Ko Xieng Khouang Dam Info .

The project in Oudomxay Province is on the Nam Ko river in the Nam Ou river watershed basin.

The Nam Ko river flows north through the town of Oudom Xay (Muang Xay) and continues about 15 km further north to the Nam Ko hydropower project and then further north until it joins the Nam Phak river not far east of Muang La town, just below National Road 2E.

In 2026 we see on Google Maps that the Nam Ko river is wrongly labelled as the Nam Phak river in the area south of Muang La town.

Nam Ko Oudomxay hydropower plant is a small 1.5 MW project with 8 GWh annual output capacity that has been in operation since 1996. The project is owned by EDL.
