Building waterponds with a road grader

The purpose of waterponding is to slow water flow down and give it an opportunity to soak into the soil ─ plants can only utilise rainfall when it becomes available as soil moisture.

A successful waterponding project involves four steps:

1) planning,

2) surveying,

3) building, and

4) management post construction.

In this presentation we focus on the third stage: building waterponds with a road grader. Join Matt Fletcher (Development Officer – Department of Primary Industries and Regional Development, Western Australia), Ray Thompson (Rangeland Rehabilitation) and Jardine Mcdonald (Program Manager – Rangelands NRM) when they discuss the optimum building process. Collectively, they discuss:

  • correct bank form
  • laser gear and tine marking
  • waterponding configuration
  • horseshoe and circle waterponds – when best to use each
  • graders, seed boxes and rippers
  • key consideration points to waterpond construction
  • case study trials, the science and key points (including the cost breakdown)
  • and more…

It costs approximately $225 to waterpond one hectare (including construction and survey) and this investment can be easily lost if ponds are not built to specification. For example, building past the survey end results in an increased depth of water been ponded and often results in a breakage and draining the pond of water.

Conversely, ponds built to specification can have a lifespan of 20 years with little maintenance.
