Freshwater - Drivers and pressures (Liechtenstein)
c) What are the related key drivers (D) and pressures (P) at national level?
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.
