Why use a weir?

Resistance board weirs are becoming increasingly popular with fisheries managers due to their versatility, functionality, and reliability. They have many advantages compared to traditional rigid weir designs; especially in larger rivers, where traditional weir designs are ineffective.

Resistance board weir advantages:

• Substantial cost savings compared to a rigid weir
• Simple, yet functional design leads to straight forward installation and maintenance
• Efficient routine maintenance
• Modular design facilitates installation and removal and custom modification
• Can be transported and installed in remote locations
• Greater capacity to withstand higher flow levels, depths and debris loads
• More resistant to 'blow-out'
  • Reduced down-time following blow-out events
  • Reduced repair costs
• Can accommodate safe boat passage
