The Samina comes into existence at Ölersegg (meeting point of Triesenberg, an exclave of Schaan (Brandegg) and an exclave of Balzers), where the rivers Stägerbach and Valorschbach merge.

In general the Saminatal is not very populated or exploited, therefore its wildlife is almost untouched. Many endangered animals and plants exist there. There is one hydro-electric power station at Samina, which from 2011 to 2015 was transformed into a pumped-storage power station. The pump-storage reservoir has to always leave some water to the river, the amounts fixed by the Liechtenstein law for protection of water. There are measures taken to ensure the ecological conditions of the river. Nonetheless there is critique from ecologists, that these amounts are by far not enough to protect the wildlife in the river. Austria
