#4 Sediment Forebay - II
Direct maintenance access by heavy equipment should be provided to the forebay
Harden forebay bottom to make sediment removal easier
Provide a vertical sediment depth marker in the forebay, to measure sediment deposition over time
Notes:
Properly functioning forebays will require maintenance in the form of sediment removal much more frequently than the permanent pool areas. Consequently, it is important to provide adequate access for heavy equipment, as shown in the next slide.
