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

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

There is another Nam Ko reservoir in Xieng Khouang Province and you can see our separate web page for this other project 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.

Location of Nam Ko dam & reservoir is seen on satellite images shown below at coordinates - 20°47'33.5"N 102°07'03.0"E (20.792639, 102.117493). (note: Nam Ko river is wrongly labelled as the Nam Phak river on Google Maps satellite images in 2024 at these coordinates).

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.

From the satellite images we can see a small reservoir south of the dam which indicates a run-of-river style project. We also see a rectangular-shaped pond on the discharge side of the dam structure which may be a regulating pond used to release flows downstream in a regular and continuous manner.
