The lake of Potamoi is in the Amari municipality, at the end of the Patsos gorge, in a very green valley with some hillocks next to it.

The lake is about 25 kilometers from Rethimno and one of the most important water lands of the south-eastern Mediterranean. Its construction was completed in 2009.

The dam became famous in July of 2014 when, going to put out a fire, two firefighters found a 2-meter crocodile in the lake. The crocodile became the sightseeing of the area as that species of reptiles is not included in the fauna of Crete. It was left in the area by someone that kept it in his house.
