About the data
Switzerland is where BrrChecker was born. The federal office BAFU measures the Rhine, Aare, Limmat, Reuss and the big lake outlets around the clock, wiewarm.ch and the lidos report their pools and lake baths from Zurich to Lake Geneva, and Eawag's Alplakes models complete the large lakes. On top comes the lido portal: operators report their own temperature directly, free of charge.
