The river Kleine Krems, 14km long and 5-7m wide, is a feeding tributary of the river Große Krems on the right-hand bank near the village of Kottes, similar in character, and crosses wooded, sparsely populated hilly country in northern Lower Austria.

This river whose banks have to a great extent been left untouched is meandering through a region hardly exploited by agriculture and forestry, of sometimes gorge-like character.

The fish stock is dominated by an especially beautiful type of brown trout with the rainbow trout representing here a minority.

It is compulsory to have an official fishing- or guest license for Lower Austria.
