Umiam Lake is one of the biggest artificial lakes in Meghalaya that is situated about 15 km from Shillong. It is more easily recognised as Bara Pani, and covers an area of about 220 sq km. The surrounding Sylvan Hills and green Khasi pines add to the majesty of this vast lake, which was created when the Umiam river was dammed to store water for hydroelectric power generation. Though it was initially established as a dam or a reservoir, it is now a popular tourist attraction. It is also known for water sports and adventure facilities such as kayaking, water cycling, scooting and boating.

Since the lake boasts picturesque and panoramic surroundings, it is often compared with the beautiful lakes of Scotland. There is a lovely garden near its shores called the Lum Nehru Park, which is a must-visit point for birdwatchers. Apart from being a popular picnic spot, the park is also known for its orchid house, aviary and sprawling lawns. It is dotted with huge pine trees on either side and has a lot of space where children can play.
