Short answer: Day 5 at Razorback marked the completion of a challenging dam repair project that required persistent problem-solving across multiple days of difficult conditions. The final stages focused on confirming the seal was holding and completing compaction of the repaired sections. The project demonstrated that even severely leaking dams can be successfully rehabilitated with …
Short answer: Traditional dam building techniques including careful clay selection, layered compaction, and hand-shaped spillways remain highly effective and are still widely used by experienced dam builders today. These time-tested methods have proven their reliability over decades of Australian agricultural history. Last updated: April 2026 | Author: Angus Hughson, Big Ditch Aquatecture While the dam …
Short answer: Sealing Razorback Dam required identifying the exact pathways through which water was escaping and applying targeted compaction and clay work to permanently stop the leaks. The project involved reworking sections of the dam wall and carefully monitoring the results to ensure a lasting seal. The Razorback Dam Seal works in progress. Day 3. …
Short answer: Day 2 at Razorback Dam focused on directly addressing the source of the leak, with the team excavating into the problem area and beginning the compaction work needed to turn the situation around. Progress was challenging due to soil conditions, but targeted intervention started to show results. Razorback Day 2: Tackling The Leak …
When you want to calculate how big your dam should be – use this simple formula. 4 units of storage for every 1 unit of required water
The Parry Project at Kendall NSW was a refurbishment of a 10 year old leaky dam that refused to hold any water for longer than a few weeks. The result was stunning
Is it a good idea to create a new dam around a small existing dam?
Long story short, the answer is no – because dams need separation from each other.
The reason being, in hydrology physics and the study of morphology (form and structure) of dam wall design, you need a wet side and a dry side to ensure wall stability
This is achieved through the process of transpiration
