It is part of the Vantaa River watershed, which descends stepwise to Lake Valkjärvi with a length of 150 meters.The rapids themselves start from a river excavated into the rock, to which the water of the Luhtajoki River flows soon after crossing the Loppi Road and then the old stone arch bridge. After the rocky outcrop, the water falls down in three large stumps, then bubbling through the woods into a rural landscape filled with fields. The field before the Loppi Road undercut by the rapids is the former drained Lake Kuhajärvi.Kuhakoski's waterfalls has played an important part in the history of Nurmijärvi, as the rapids were once the most important mill rapids in the area. Since the beginning of the 16th century, four separate mills (the mills of the villages of Perttula, Uotila, Valkjärvi and Numlahti) and later also sawmilling have been operated in the rapids. In 1910, a small power plant was built in Kuhakoski by the Perttula and Uotila houses. The operation of the power plant continued until 1952. Even today, the foundations and ruins of the mills can be seen in the waterfall, reminiscent of the industrial history of the rapids. Other identifiable landmarks include the semi-two-storey brick building above the Valkjärventie road above the rapids, which was a former machine and car repair shop in Perttula from 1937 to 1972.In the northern part of the rapids, and especially in its eastern part, there is dry meadow, and on the rock along the rapids, bluebells and maiden pinks grow, among other things.

Klaukkala (Finnish: [ˈklɑu̯ˌkːɑlɑ]; Swedish: Klövskog [ˈklø̂ːvskuːɡ], Finland Swedish: [ˈkløːvskuːɡ]) is the southern-most urban area (Finnish: taajama) of the Nurmijärvi municipality in Uusimaa, Finland, located near Lake Valkjärvi. It is the largest urban area in Nurmijärvi, and despite the fact that it officially has the status of a village, it is often mistakenly thought to be a separate town due to its size and structure. In the 2010s, Klaukkala's urban area grew to be part of the larger Helsinki urban area. Klaukkala has a population of over 20,000 and is the fastest-growing area of Nurmijärvi; almost half of the total population of the municipality lives in Klaukkala. Its population began to rise in the 1960s, when it surpassed the church village of Nurmijärvi. In the 1970s, Klaukkala also grew larger than Rajamäki, which until then was the largest of Nurmijärvi's villages. At that time, Klaukkala's population was over 2,500. Klaukkala has significant migration mainly from the Helsinki conurbation; being a rural village a half-hour's drive away from the Helsinki centre, it especially attracts families with children. Unfortunately, due to the enormous population growth, the village is also infamous for its growing traffic, which causes local problems at the mornings and afternoons.In the early 2000s, many detached houses were built in Klaukkala, but the situation has changed as up to three-quarters of the new houses are apartment, terraced and semi-detached houses.
