Important Vegetation Management for Dams: What to Plant and What to Remove

As a dam builder with over 30 years in the industry, I have seen first-hand how vegetation can make or break the long-term safety, functionality, and environmental value of a dam.

Whether you’re managing a farm dam in New South Wales or a larger water storage elsewhere, the right approach to vegetation is essential for water quality, dam stability, biodiversity, and operational safety.

In this comprehensive guide, I’ll outline the principles of vegetation management for dams, detail what to plant and what to remove, and share practical advice for dam owners seeking to optimise both ecological and engineering outcomes.

10 Ways to Select the Best Site for your Farm Dam

Water is the most important thing for any farm, and a well-placed farm dam can keep your water safe for decades. I’ve been building and designing dams for more than 30 years, and I can tell you that choosing the right site is the most important thing you can do when building a new dam. If you pick the wrong site, it could cost you a lot of money, cause problems with upkeep, and even hurt the environment. On the other hand, a well-chosen site will give you reliable, high-quality water with little work on your part.

Solar Panels for Farm Dams to Stop Evaporation

Water is very important for farming. Farm dams are crucial for irrigation, cattle, and keeping rural communities alive in Australia and around the world.

But every year, millions of litres of valuable water are lost to evaporation, especially in hot, dry places like much of inland Australia.

How Much Water Are You Losing To Evaporation

How Much Water Is Your Dam Losing To Evaporation?

Evaporation loss from farm dams in Australia is a great challenge to water security, ranging from 9% to 36% loss of total volume of water in summer. Reliable quantification and prediction of losses are complicated by numerous factors that include meteorology, dam shape, and inaccuracies in measurement. This paper explores the complexities of evaporation estimation, the limitations of current practice, and the potential for improvement through advanced modeling and abatement technologies like floating covers and windbreaks. Understanding these dynamics is essential to effectively manage water in Australia’s agricultural regions.
