The article presents the results of five-year calibrating period before drainage and one year after drainage. The observation was performed in the mountains waterlogged watershed (32.6 ha) in the Orlicke hory Mts. (eastern Bohemia). The influence of drainage increased occurrence frequency of average daily flow from the interval 2-4 L.s/l to the interval 4-6 L.s/l. The change of peak flow was not registered but the shape of unit hydrograph was changed in the culmination segment. For the present, the water table depressed about 8 cm in average value. Negative effect of drainage on water regime of presented catchment was not proved.
