Freshwater - Drivers and pressures (Liechtenstein)

The findings of the national groundwater monitoring show that the quality of groundwater is good.

The water network encompasses over 450 km of rivers. About 60 % have been considerably altered by construction work or are culverted. These watercourses, which are narrowed and often straightened, need space for their numerous functions.

The Alpine-Rhine at the border of Liechtenstein is affected by heavy short-term runoff variations due to the production of repetitive peak forward current at hydro-power plants upstream. Therefore, monitoring show shortcomings in evidence of the fish population.
