Kiikunlähde (The Kiikku spring) is the biggest spring pond in Finland according to Hollola municipality's tourism website. It is 400 meters long and the widest point is 100 meters.
Kiikunlähde spring has 14 spring beckets which erupt water about 7000m3 daily. In the northern end there is a dam, which has raised the spring pond's surface a few meters and thus formed a small waterfall and a constant year-round stream for mill and sawmill that situated next to the dam. The water continues its' journey along Kiikunoja (The Kiikku ditch) to lake Vesijärvi near the stone church of Hollola. Water temperature in the spring becket is about five degrees, so it doesn't freeze in winter. Hydrogeologically Kiikunlähde is part of Southern Finland's biggest groundwater reservoir, that erupts to three different directions, for example to the Gulf of Finland.
