The closed Kairiai landfill still remains a serious source of pollution. In some sites of Kairiai landfill test-ecosystem, water pollution exceeds “safe” concentration by 260 to 860-fold. While ecological conditions of water bodies are commonly assessed according to physical, chemical or hydro morphological criteria. The goal of this study was to investigate a long-term effect of landfill pollution on fish community’s parameters and ecological status according to Lithuanian Fish Index (LFI) and Lithuanian Fish Index for Lakes (LFIL) in 2012–2013 study period. Estimates of LFI of indicate that ecological potential in the drainage channel varied from poor to bad (LFI 0.07– 0.17). Variation among LFIL estimates (on average 0.45±0.003) in the Ginkūnai Pond was very limited and represented moderate ecological status of the whole water body. In Švedė Creek, LFI values (0.15–0.35) varied in relation to distance from the pond and corresponded for poor to moderate ecological potential.
