Slow going — pick your moments
River temperature is the limiting factor today, not the flow. Fish dawn or dusk if you go at all, and handle everything with extra care.

About this water

Private trophy salmonid fishery on the Otava with its own permit system. Managed for quality — larger fish, lower pressure, potentially stricter rules than the general Otava sections. Represents the Czech model of premium beat management where conservation and quality fishing go hand in hand.
