The water inflow structure for a hydroelectric generator system has a step which cooperates with two adjacent blades of a runner to retain a quantity of water, the weight of which rotates the runner. Each blade of the runner has a forward surface which is inclined when the blade is at its highest position, to prevent water from overlying the runner shaft to produce reverse rotation. An inflow opening is formed in the step to admit water past a blade which is at the step.
