The river Suhodolnica is the main source of drinking water for the Slovenj Gradec basin due to its extra clear upper stream. Even the endangered species can be found here, especially freshwater crayfish. The bottom is lime and stone.

The river creates numerous pools in its lower course as well as smaller rapids where brown and brook trouts live.
