All drainage districts in the State of Arkansas, whether created by special act or otherwise, are authorized, when considered practicable by the board of commissioners or directors of any such district, to make any necessary surveys for the securing of federal aid and assistance in the construction of dams and reservoirs for impounding of head waters which cause floods that overflow the ditches, wash away the levees and crops, and erode the lands in the district.
