Did you know some earthen dams and ponds can actually become better at holding water as they age? 💧
It sounds strange, but there's some interesting science behind it.
Over time, fine clay, silt and organic particles can settle on the bottom of a pond, gradually forming a natural barrier that slows water seeping into the ground.
This process, sometimes called self-sealing, helps explain why certain old farm ponds can hold water for generations, while newer ponds nearby struggle to retain it.
But it's not just about age. Soil composition, underground rock formations and the way a pond was originally constructed all make a difference.
And while some ponds benefit from this natural sealing process, others can develop leaks as the ground shifts, dries or cracks.
It's a reminder that what happens beneath a pond is often just as important as the water we see on the surface.
