A lazy river is a water ride found in water parks, hotels, resorts, and recreation centers, which usually consists of a shallow (less than 1,2 meters) pool that flows similarly to a river. There is generally a slow current, usually just
enough to allow guests to gently ride along lying on rafts. There may also be scenic elements added, such as small waterfalls on the edge of the river. Some lead into wave pools, while some just go around in circles.
Generally Aqua parks keep the length of the lazy river short cause if high electricity cost. Bellagio Water Parks use special engines and circulate the water in an efficient way with less cost.
