Darland's Lake Nature Reserve is a nature reserve south of Totteridge Village in Barnet, England. The lake is very shallow, with extensive reed beds, and the reserve also includes woodland. It has a diverse range of breeding birds and eighteen species of mammal, including stoat and weasel. It is also of value for grass snakes, amphibians, fungi and invertebrates.
Folly Brook and Darland's Lake Nature Reserve are together designated a Local Nature Reserve, Borough Grade 1. Darland's Lake was formerly designated a Site of Special Scientific Interest, but the designation was withdrawn when it was discovered that the rarest plants had been introduced.
