Due to the unblemished nature and the lack of industry and bigger settlements this district guarantees a completely natural basin. Numerous pools that are followed with rapids and areas of the calmer current give plenty of living space to brown and rainbow trouts, but also chubs can wander into the district.
Access to water is good everywhere along the local road Mirna - Gabrovka that runs through the valley.
