Movable and adjustable dam

A movable and adjustable dam for generating power, comprising:

• two wall members spaced apart from each other so as to form a channel there between;
• a water wheel rotatably mounted between said wall members to be driven by flowing water in said channel;
• and
• an adjustable dam floor between said wall members, comprising;
• a draft plate slidably mounted between said wall members;
• a penstock plate operatively connected to said draft plate;
• an inlet plate slidably mounted to said penstock plate;
• an outlet plate operatively connected to said draft plate;
• whereby adjustment of said penstock plate effects correlative adjustment of said draft plate so as to convert operational modes of the dam to maximize power-generating capacity of said water wheel.

A method for providing an adjustable dam, comprising the steps of:

• providing two wall members spaced apart from each other, each having an inner side, an outer side, an inlet edge and an outlet edge;
• providing an adjustable dam floor secured between said wall members;
• providing a water wheel rotatably mounted between said wall members;
• placing said wall members between banks of a flowing body of water to effectively secure said wall members in a watertight fit between said outer sides of said wall members and said banks of said flowing body of water and to form a channel between said inner sides;
• directing said flowing body of water past said inlet edges, into said channel, and over said adjustable dam floor to rotate said water wheel before said flowing body of water exits through said outlet edges;
• and
• adjusting said dam floor to a desired height, said height of said dam floor controlling the water level upstream from said water wheel and thus controlling the operational modes of said water wheel.
