The stream Poreznica runs through the gully Zakojška grapa, across the steep terrain to the western side of Porezen, the highest mountain in the Cerkno region. On its path to the valley, the stream has created numerous small and large waterfalls, rapids and pools. It runs through the forest and preserved wilderness, since this area has been uninhabited for many years. However, in the past this part of Porezen was settled, mills and sawmills were located on the stream until the great flood in 1926.
Nowadays Poreznica is the home of a fish farm where pure Marble trout is bred.
