The results of measurements conducted in 2010 of methane emission from the surface of the Nielisz Reservoir on the River Wieprz have been presented. This is a lowland reservoir located in the forested areas of the South-Eastern Poland (The Central Roztocze). The content and isotopic composition of methane in the upper (1 cm) layer of the bottom sediment have also been examined. The methane flux ranged from 15.98 to 383.85 mmolźm-2źd -1, while concentrations of the gas in pore water ranged from 133.33 to 1265.45 žmolźdm-3, and the value of ? 13C-CH4 was within the range -8.05 and -56.22%o. The fractionation coefficients (?cCH4-CO2) between methane and ?CO2 equalled approximately 1.05. The results of investigations suggest that methane in the sediment of the Nielisz Reservoir is produced by acetate fermentation. Levels of emission of this gas to the atmosphere can be compared with the values reported for large tropical reservoirs.
