Check dams

{plain list|1=

• Check dams usually consist of crushed rock gabions, or pre-treated timber up to 0.6 m in height.
• Rocks used in check dams should have median diameter 25-75 mm.
• The spacing of dams should not exceed the horizontal distance from the toe of the upstream dam to the same elevation on the downstream dam.
• Where check dams are used, the maximum design depth of ponded water must be 0.5 m.}

Structures constructed of a non-erosive material, such as suitably sized aggregate, wood, gabions, riprap, or concrete; used to slow runoff water. Can be employed in practices such as bioswales and enhanced grass swales.
