Pyhäjärvi

Pyhäjärvi is a lake in southern Finland. The name means "holy lake". Pyhäjärvi is shaped like the letter "C" with the cities of Tampere and Nokia 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.
