So I installed a huge 80ft round 6 foot deep pond/lake liner in my pond this summer. It has a slow trickle of a creek that feeds it. I filled the pond with water and its holding great. I have a small trickle of a creek that feeds it..but at the point of where the creek enters the pond is tricky. Ive built a little in-creek/pre-pond before is spills into the lined pond. That pond isnt lined. The pre-pond is always full...yet its not full ENOUGH to spill over into the lined pond. (It does when it rains). But WHERE is the trickle water going? I thought it might be going UNDER the liner...but it isnt. Ive felt around in there... Its not bubbling up. The weight of the water is holding it down. But WHERE is the water going? Very odd?
