We supplied and installed Rollgum EPDM liner in this recently dug dam. The water will fill up to the edge of the rock when its full. The muddiness in the water is from the rocks which the client was forced to lay down as a council requirement because the land around the dam has a lot of springs. The turbidity of the water will clear when the soil settles. We also installed a Vertex aeration system to keep the water healthy and clear of algae and weeds ongoing.
