PROBLEM TO BE SOLVED: To provide float selective water intake equipment capable of effectively taking water by automatically following variations in the water level, reducing the connection with a civil engineering structure to simply construction work, substantially lowering a sticking phenomenon with an impervious curtain, an underwater float and a different impervious curtain located on the inside thereof without being required for spreading an impervious curtain until it reaches the bottom of a dam lake and decreasing lifting and lowering resistance. SOLUTION: The float selective water intake equipment includes a water float 5 surrounding a water intake 2a and rising and falling by buoyancy in accordance with the water level, an elevator 8 mounted to the water float, a plurality of water floats 6A to 6E provided to up and down multistage capable of rising and falling underwater with the elevator and so as to hold a predetermined interval H, a plurality of impervious curtains 7A to 7D capable of sealing water and fixing the upper ends of them to the underwater float and provided by overlapping the lower ends with the lower side underwater float, a horizontal impervious member 12 fixed to a weir levee 1 and horizontally partitioning the inside of the impervious curtain and a fixed supporting member 14 fixed to the downward weir levee from the horizontal impervious member and supporting the falling underwater float.
