Apparatus for generating hydroelectric power comprising a portable collector tube assembly which can be transported to the site of a water source having a waterfall sufficient in magnitude to provide a pressure head for driving a turbine generator. The tube assembly comprises telescopically arranged inner and outer tubes, and means for rotating the tube assembly and extending the inner tube so as to place the upper, extended end thereof in a position within and below the top of the waterfall so as to take advantage of the resulting hydrodynamic and hydrostatic forces.
