Rain and the waterlevel of Lake Trasimeno
Today we finally had a decent day after a long period of rain, rain and more rain. There also is a good side to all the rain: the waterlevels of Lake Trasimeno have risen significantly.
The past weeks the inhabitants of the lake area closely watch its waterlevel. The historic “zero level” has been reached earlier this month and we are now at about +10 cm. The lake is only fed by rain water, there are no rivers or mountain streams ending up in the lake. It is like an extra large water reservoir and its waterlevels have always been a concern. It is said that even in the times of the Etruscans and Romans they tried to find ways to stabilise the waterlevels of the lake. The Romans even made a canal towards the Tiber river to drain the water in case its level was too high. This canal (and a modern version next to it) is still visible at the Oasi della Valle, a bird watching reserve. villainumbria.wordpress.com/2014/02/13/high-water-levels-at-lake-trasimeno-umbria/
