Studies on the relationship between the rainfall, water levels and floods in Asa Dam Ilorin, Kwara State Nigeria was carried out for twelve months to determine the impact of these parameters on the supply of fish species from this dam to Ilorin and environ. Maximum rainfall (26.14 cm) was in September. The range values of rainfall recorded during this research was zero (November / February) to 26.14 cm (September). Water levels were lowest in April (11.40 m) and highest in September (12.80 cm). Increased water levels commenced from May (11.90 m) to October (12.60 m). The flooding of the dam began as from August when the dam spillway began to overflow. Assessment of fish catch from six fishermen around the lake showed significant increase in the fish supply at the dry season when water levels were low than the wet season (P < 0.05). Rainfall and water levels were negatively correlated.Page Range
