The downstream river of the tropical Batang Ai Dam is experiencing diurnal flow fluctuation due to power generation operation.
Three samplings were conducted to collect the water quality and fish assemblage data and one sampling was conducted to study the hydrological characteristics of the downstream river.
The results show that the downstream river is extremely shallow and moves slowly when the power generation is halted and no water is discharged from the powerhouse.
Significant correlations between river flow and pH, dissolved oxygen (DO), total suspended solids (TSS), and five-day biochemical oxygen demand (BOD5) indicated that those parameters were influenced by the water discharge regulation.
Fish abundance was low in upstream segment but it gradually increased as distance from the dam increased and was significantly correlated with DO.
Fish diversity in the downstream river was influenced by the river depth and chlorophyll a concentration.
The most abundant fish species, Cyclocheilichthys apogon, exhibited a negative allometric growth pattern, while Hampala macrolepidota and Hemibagrus planiceps exhibited an isometric growth pattern.
Fulton’s condition factor (K) values for 89.4% of H.
planiceps were ≤1, indicating poor to extremely poor conditions.
