Of the many devices capable of converting power from open river flow or head differential,
no other technology has been adapted for similar low-head dam utilization.

Background and History

Low Head Dam Background
What is a "low-head" dam?
—A low-head dam is defined as one having an elevation difference of less than 15 feet
How many low-head dams exisit?

There are over 72,000 low-head dams across the United States.

When where they built?
—These were primarily constructed prior to 1950 on non-commercially navigable rivers to provide flood control and a reliable source of water for adjacent industries.
How are they maintained?
—There is very little standardization in the design of the dam structures.  Most are operated and maintained by local government agencies or the Army Corp of Engineers.
Do they have any safety issues?
—The water turbulence on the downstream side of the dam is considered extremely dangerous and inhibits recreational use of the river.

The Williams Cross-Flow Turbine

The Williams Cross-Flow Turbine

Mr. Fred E. Williams, Jr. was awarded a patent in 1999 for a device that addressed the ability to capture the power provided by the flow of water over the weir of a low-head dam.

—This design has since been refined to include provisions which…
  • —Provide enhanced recreational safety
  • —Minimize impacts to aquatic biology
  • —Eliminate structural modifications of the dams
  • —Minimize visual impact
—A second patent was awarded in 2005 related to the turbine housing, and a third patent is pending at this time to incorporate further design improvements.
