How much does it cost to build a farm dam?
Farm-scale irrigation dams are expensive to build. They are even more expensive to build twice, in the event of a partial or calamitous failure. The costs involved in building a large earth dam with a capacity in the order of 4 GL may easily exceed $1.5 million, even at a favourable site.
Can I build a dam on my farm?
The NSW Office of Water can advise as to what size you can build without needing a licence. If a larger capacity is needed, then a licence may need to be issued. Farm dams can be built on minor watercourses (lower order streams) but not on larger streams, unless they are approved by the Office of Water.
How do you build a dam?
Streams and rivers have to be diverted to create a dry area to construct the dam. Small rivers and streams are usually diverted through a tunnel, or a channel that is constructed around the side of the dam. Soft soils and rocks are excavated to form the route, while harder rocks have to be blasted with explosives.
How do you build a dam for a pond?
A pond dam and spillway are for a pond that has an incoming water source; they don’t apply to a pond of standing water.
- Locate the water source that feeds water to the pond.
- Place large rocks 6 feet upstream from where the water source meets the edge of the pond to create a temporary dam.
Do you need a permit to build a dam?
Rural landholders in NSW are entitled to build and maintain dams up to a certain size without a licence. Those not requiring any licence include: dams up to one megalitre on small properties where the property was approved for subdivision before 1 January 1999.
How big is a 1 megalitre dam?
One megalitre is equal to one million litres and one gigalitre equals 1000 million litres. The numbers sound big, but what do they really look like? A standard Olympic-size swimming pool contains 2.5 ML or 2,500,000 litres of water. Sydney Harbour holds about 500 GL.
How do you build a healthy dam?
Add logs, rocks, trees and shrubs to the dam area
Enhance the habitat and encourage native wildlife to colonise the dam by adding rocks, logs, trees and shrubs to the area. Trees and shrubs can also help to reduce evaporation by reducing wind and shading the water.
How do you calculate the size of a dam?
The surface area of a dam is calculated by multiplying the length by the width. Example: 30 metres X 50 metres = 1500 m2. This will be the case for square or rectangular dams. Most dams start out as a square or rectangle, but over time appear to become rounded.
What is a farm dam?
A farm dam in this article refers to an ‘on-stream dam‘. They are typically a barrier built on a surface water flow path for the purpose of holding back and storing the runoff or flow along that flow path, which otherwise would flow downstream.

How deep should a 1 acre pond be?
Preparing for a Farm Pond
The pond should be at least 1 acre in size. Smaller ponds can work, but pose some difficulties in managing the fish population. Fish ponds should be at least 6 feet deep, but no more than 12 to 15 feet deep.
Can you just dig a hole for a pond?
The deeper you can dig, the better the pond will look. It’s tough to make a pond look natural when it’s sitting 18 inches above the surrounding soil. The easiest way to handle this problem is to dig the pond with a flat bottom, with the side gently sloping into the middle. Once the pond is dug, you have two options.
Can a pond be built anywhere?
Though a pond can be installed on nearly any type of land, your soil has to be compatible or the water won’t hold. Cliff refers to soil that holds water as “plastic soil.”
