Valkjärvi is a lake located in the Nurmijärvi municipality in Southern Finland. It is an island-free lake in the immediate vicinity of Klaukkala's urban area. The water flows from the lake along the Luhtajoki River all the way to the Vantaa River.[1]

Valkjärvi is the most lushest lake of Nurmijärvi,[2][3] and it is part of the Nurmijärvi's lake monitoring program of the Central Uusimaa Environment Centre (Keski-Uudenmaan ympäristökeskus) due to its poor oxygen values near the bottom of the lake, which are observed especially in summer and winter under ice.[4][5] Blue-green algae are quite common in the lake; in July 2015, the phytoplankton in the lake with the highest total biomass consisted of 40% cyanobacteria and 29% cryptomonad.[2]

Despite all this, Valkjärvi has great recreational value and there are quite a lot of both permanent and holiday settlements around the lake.[5] There are two beaches at the southern end of Valkjärvi: Tiiranranta Beach and Lähtelä Beach.[6]
