Our visit was in September, a few years back, when the waterfall had just about a decent flow. Few enthusiasts even trekked down to the base for a swim in the hot sun. Bhandardara is a place to just relax, laze, eat, sleep & if that gets too boring in a day, its best to visit the waterfall, Wilson dam (quite ancient) and the local market for the amazing colourful sights and cheerful local folks. And for early risers, there's another spot - the Bird Sanctuary, a short drive away, but dont expect to see birds, not many left anymore :(
