Virroijoki

Virroijoki is a river located in the Pirkanmaa region of Finland. It is a tributary of the Ruovesi lake, which is part of the Kokemäenjoki river system. The Virroijoki flows through the municipality of Virrat, from which it derives its name. The river is characterized by its relatively slow current and a landscape that is typical of Finnish Lakeland, featuring forests, bogs, and scattered settlements.

The length of the Virroijoki is approximately 20 kilometers. Its source is the lake named Vaskivesi, and it flows generally in a southeasterly direction. The river's course is marked by several rapids and smaller waterfalls, though these are not significant enough to impede navigation for small boats in many sections. The riverbed is primarily composed of sand and gravel, with occasional rocky outcrops.

Historically, the Virroijoki has been used for timber floating, a common practice in Finland's past that utilized waterways to transport logs from forests to sawmills. Today, its primary role is ecological, supporting a diverse aquatic ecosystem. The river supports fish populations such as perch, pike, and zander, and its banks provide habitat for various bird species. The surrounding areas are popular for recreational activities like fishing, canoeing, and hiking, with several marked trails and fishing spots accessible along its course. The water quality of the Virroijoki is generally considered good, reflecting the relatively unpolluted nature of the Finnish countryside.
