• A nearby landowner knows them well and calls them “fall-downs”. They were put there in the 1960s to catch sediment and control erosion for the Lake Burley Griffin catchment when the lake first started filling up. There were many dams put in there as well at the same time. Source: Via Col McA, Graham S, from Judith T and David W.
• David is correct – extensive work was undertaken in the Kowen area to try and improve the water runoff and quality into the Lake. This is why you will see many erosion control structures and an abnormally large amount of dams. The area was degraded farm land before the pines were planted and in fact much of it was so infested by wattle scrub that it was useless for any form of land management.
