Pyhäjärvi

Lake in southern Finland. The name means "holy lake". Lake P~ is shaped like the letter "C" with the cities of Tampere and Nokia (city) on the northern end, and Hämeenlinna at the southern.

The lake is fed by the water running through the Tammerkoski rapids in the center of the city of Tampere. Because of the rapids, the water in Pyhäjärvi is warmer and richer in ozone than that in the northern lake Näsijärvi. As an effect, the life in this lake is richer, but the water is also more polluted - by Finnish standards, which means it's still safe to drink by international standards :-)
