Flashboard Risers

A flashboard riser, or weir box, is an overflow-type dam commonly used to control the water level in crop irrigation or ponds.
 
Water flows over the top board or dam of the flashboard riser and is released at a level below the top of the weir. The crest of an overflow spillway on a large dam is often called a weir.
 
 
Our flashboard risers are designed with high production,
low cost/ maintenance farming operations in mind.
Installs easily on existing culverts or new installations can
be easily replaced if damaged.
 
Each standard flashboard riser is painted with lift resistant red primer. Add a safety red paint for high visibility or Wild Grasses duck pit paint for hunting use for an additional $20.00.
