Do block ramps improve river connectivity for fish?

River restoration

The innumerable sills and weirs found along Switzerland’s rivers fragment the habitats of aquatic organisms and impede the migration of fish. These artificial barriers are therefore increasingly being replaced by block ramps. Whether such measures are effective in restoring connectivity, however, depends on the type of ramp and the fish species concerned.  >> more

Radioactivity in sediments of Lake Biel - Eawag results have been published
In the summer 2013, Eawag and the Swiss Federal Institute for NBC-Protection (LABORATORY SPIEZ) have withdrawn sediment cores from Lake Biel and examined the sediment layers for radioactivity. The study confirms the existence of a Cs-137 peak, which can be assigned to the charges published from 1999 on the nuclear power station Muehleberg. According to the Federal Office of Public Health FOPH the Cs-137 in the sediments of Lake Biel do not pose any risks to health. The full report on the study (in German) can be downloaded on the website of FOPH.
