Nordre Puttjern in 2007, after the drainage was recovered
Together with Søndre Puttjern lake right nearby, it was almost entirely dried up in 1997 due to a leak during the construction of the railway tunnel Romeriksporten.[1] The water level in Nordre Puttjern dropped 6 metres, so that the depth was reduced from 9 to 3 metres.[2]
