    We compared the structure of fish community and condition of major fish species in Lake Chungpyung and Lake Paldang which are relatively shallow meso-eutrophic cascading dam reservoirs on the North Han River. Two lakes have wide littoral zone in the lakeside providing similarly good habitat for fishes whereas fishery and water recreational activities such as motorboating water skiing are allowed in Lake Chungpyung but are prohibited in Lake Paldang. The average lengths of large size fishes in Lake Chungpyung are shorter than those of same species in Lake Paldang resulting in the slight distortion of generation distribution of those species in Lake Chungpyung possibly owing to the active fishery such as fixed shore net fishing gill net fishing and angling. Meanwhile the condition of fishes represented by the length-weight relationship of fish species did not show the significant differences between two lakes and showed normal condition. To evaluate the impact of physical disturbance such as loud noise and turbulent wave from water recreational activities to fishes precisely further studies including physiological responses to stress an spawing activity should be needed.
