Valkjärvi (lake)
Valkjärvi is the most lushest lake of Nurmijärvi, 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. 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.
Despite all this, Valkjärvi has great recreational value and there are quite a lot of both permanent and holiday settlements around the lake. There are two beaches at the southern end of Valkjärvi: Tiiranranta Beach and Lähtelä Beach.
