Rawal Lake is located within an isolated section of the Margalla Hills National Park.
The reservoir is of considerable importance for wintering waterfowl, especially Anas platyrhynchos.
Resident mammals include the common fox, Pangolin, Porcupine, Jungle cat, Jackal, Wild boar and yellow-throated marten.
Reptiles include indian cobra and Russell’s viper.
It is a good place for birds watching, as the majority of Birds of Islamabad are found here.
