Increased fish production is usually promoted as an important secondary benefit of reservoirs created for hydropower, irrigation or water supply. Dam proponents present increased fishery as a benefit for local people in compensation for disruption to livelihoods caused by dam construction. However, reservoir fisheries often fail to live up to expectations. Follow this link :

RRA Report on the Profile of Nam Ou Watershed, Phongsaly Province http://mwi.mrcmekong.org/index.php/watershed-blogs/item/55-rra-report-on-the-profile-of-nam-ou-watershed-phongsaly-province http://mwi.mrcmekong.org/index.php/watershed-blogs/item/55-rra-report-on-the-profile-of-nam-ou-watershed-phongsaly-province
This report is prepared as a consequence of the Mid Term Report Review (MTR) of the project entitles "Poverty Reduction and Environmental management in Remote Greater Mekong Subregion Watershed" (Phase I) under the support of Regional Environmental Technical Assistance Project (RETA, No. 5771) and Science Technology and Environment Organisation (STENO). As a result of the MTR workshop, Nam Ou Watershed was selected and proposed as the potential and priority site for further study and development in according to the criteria set by RETA.

This report is a result of a short-term study of the Nam Ou watershed with priority areas given in Phongsaly Province. The study aim to present profile and overview of Nam Ou watershed in terms of socio-economic development and natural resource management as well as how local minor ethnic people develop their livelihood. This report also try to compile some of the intervention measures carried out and promoted by government and other international support projects active in the areas.

Effects of Dams on Downstream Reservoir Fisheries, Case of Nam Ngum http://mwi.mrcmekong.org/index.php/watershed-blogs/item/54-effects-of-dams-on-downstream-reservoir-fisheries-case-of-nam-ngum http://mwi.mrcmekong.org/index.php/watershed-blogs/item/54-effects-of-dams-on-downstream-reservoir-fisheries-case-of-nam-ngum
In 1971 the first hydropower dam in the Lao PDR was completed. The construction of the dam in the Nam Ngum River created a reservoir with an area of 450 km2 at full supply level. Electricity generated at the Narn Ngurn power- house has been the major foreign currency earner for the Lao PDR. The current annual gross power revenues of the Nam Ngum I dam are estimated at approximately US$36 million. The Nam Xong water diversion scheme came on line in 1995. The Nam Leuk hydropower and water diversion project is under construction. Another six hydropower projects upstream of the existing Nam Ngum reservoir are under consideration (see Map). A definite positive impact of hydropower development is the fish production and economic value of fisheries in newly created reservoirs. This article discusses potential impacts of hydropower development on down- stream reservoir fisheries and aquatic diversity. Information used for this paper has been gathered during the Nam Ngum Watershed Management technical assistance project, co-financed by the Asian Development Bank (ADB) and the Government of Denmark.
