Water quality of rivers that flow into bakun hydroelectric dam reservoir, Sarawak, Malaysia / Teck-Yee Ling, Lee Nyanti and Annestasia Simbut John Masion

After Bakun Dam was filled to its full supply level 2 years ago, little is known about the water quality of the rivers that flow into the reservoir. After the impoundment, sections of rivers of Batang Balui were submerged. Those rivers are still important for aquatic organisms and they will affect t...
