About this water

One of the best trout fisheries in the country — fly-fishing only, barbless hooks only, with elevated takeable size limits for grayling and brown trout stricter than the national baseline. Brown trout, rainbow trout and grayling in water where Czech nymphing was developed and perfected. A showcase fishery with beat-specific management that sets the standard for Czech quality-section regulation. WFD ecological status is 'Bad', likely reflecting upstream pressures on the wider Vltava rather than the managed fishery itself — the fly-only beats remain highly productive.
