A low head water turbine (2) comprising a runner (6) having a cylindrical outer surface (8) extending between opposite ends (10) and a plurality of similar blades (12) having inner (14) and outer (16) sides extending to ends. The blades are similarly pivotably secured along their inner sides (14) to the outer surface of the runner so as to pivot in the direction of rotation of the runner between closed position lying adjacent the outer surface of the runner and open position at an angle thereto. A housing having (24) end walls (26) and a rounded side wall (28) extending therebetween, completely encases the runner and its blades. The runner is eccentrically mounted to the end walls of the housing for rotation about a horizontal axis (A) so that the cylindrical outer surface of the runner is spaced closer to an upper portion (30) of the housing side wall and farther from a lower portion (32). A water inlet (34) opening is located in a lower, forward portion of the housing, below the axis of rotation of the runner. A water outlet opening (38) is located in a lower, rearward portion of the housing.
