Pond Boss Forums POND CONSTRUCTION Selecting a site New Pond / Tree Roots ...will they cause leaks?

SJO, GENERALLY speaking, tress along natural shorelines will not cause leakage issues unless as Bill D pointed out, the pond had to be clay lined because of poor soils available. In the Dam, however, any tree root that grows through the dam and enters the water will eventually die, decay, and provide a hole for water to run through.
