The present work was carried out in Chenani hydroelectric reservoir to investigate its monthly variations in the physico-chemical parameters and its fish fauna during the study period of September 2011 to August 2012. Eight species of fishes which belongs to a single family i.e Cyprinidae (Schizothorax richardsonii, Tor pitutora, Cirrhinus mrigala mrigala, Garra gotyla gotyla, Labeo boga, Labeo bata, Labeo rohita and Labeo dero) were found in Chenani hydroelectric reservoir. The relative species diversity, species richness, dominance and evenness indexes were calculated. The value of Simpson index ranged between H’= 0.34(March) to 1.48(Nov.). The value of Shannon-Weiner index was higher (I= 1.81) in March and lower (I=0.96) in Sept. Species richness in term of Maraglef’s index and Menhinick’s index varied between minimum valued R1= 0.71 (Sept.) to a maximum value R1 = 2.07 (Aug.) and a minimum valued R2= 0.49 (Sept.) to a maximum value R2=1.48 (Aug.) respectively. The minimum evenness value was observed in Nov. and maximum in Oct. the values being E = 0 and E= 0.96 respectively.
