This 2014 video says about itself:
The European brook lamprey (Lampetra planeri, also known as the brook lamprey and the western brook lamprey) is a small European lamprey species that exclusively inhabits freshwater. This species should not be confused with the North American species Lampetra richardsoni, which is also called the Western brook lamprey.
Translated from Dutch NOS TV today:
De Dommel water authority [in North Brabant province in the Netherlands] pumps 1000 cubical meter of groundwater into the Reusel brook every day to save the rare brook lamprey. In a number of important places the water near Hilvarenbeek dried out last weekend. The prehistoric small fish (Lampetra planeri) is threatened with extinction.
