Nagavara Lake, along Outer Ring Road in north Bengaluru, is a picture of contrasts. One side of it makes for the perfect outing spot — with a boating facility, children's play area, and beautiful landscaping, there's plenty to keep visitors engaged. The other half is an eyesore: It's covered with hyacinth and sewage inflow has polluted the water. The lake, ironically, is located close to one of the biggest IT hubs in the City, Manyata Tech Park. The portion of it that's maintained under the public-private partnership model is a favorite hangout among locals. The access to visitors or researchers is only restricted to the cleaner parts of the lake.
