Small-dam.JPG (18627 bytes)Dams: At Yallaroo we are incorporating water features into our domestic landscape. We have both micro and macro features. We classify micro features as ponds. At present we have three ponds with more on the drawing board. Macro water features are classified as dams. Yallaroo has a number of gullies in relatively close proximity to the house. This has provided the opportunity to have a couple of dams constructed. There are two major differences between ponds and dams. Dams are larger and are not lined. They rely on a clay floor to hold water.
When we purchased Yallaroo there was one small dam, east of the house. This dam is now included in a large dam. The wall of the original dam has become an island. To the west of the house there is a small dam. The image shows this small western dam.
If you have the room, suitable soil and reasonable catchment, dams have a number of benefits: They provide irrigation water, create wildlife habitat, they become a scenic attraction, add value to your property and may be used as a source of food.
Wide ranges of organisms are attracted to dams. Frogs will occupy the rushes and sedges that grow around the margins and their tadpoles will live in the water. Aquatic insects will colonize the dam. Tortoises will also live in the water. Ducks and other water birds will rest, feed and nest on dams.
Yabbies or freshwater crayfish will soon take up residence and may be caught. Fish may also be introduced. At present we have Golden Perch and Rainbow Trout in our large dam.
Dam building is a skilled occupation. We suggest, that if you are considering building a dam, that your machinery operator is experienced in dam construction.
