I am no expert, but have an idea. If you only have one spot where water is coming out forcing its way through the clay layer. Maybe make a larger hole where water wants to force the clay up, then make a trench up hile to the ponds full level. Put a 4 or 6 inch pipe in the trench and fill hole with gravel, put 2 feet of clay over pipe and hole, but leave the upper pipe end exposed. This may keep enough pressure from the spring pushing up threw your clay liner in the dry times. May not work if you have to force the water uphill to far. May not cost much to try if you have some equipment. Everyone knows springs give water and take it. Water will find the easiest way to go, hopefully threw this pipe would be easier than through your clay liner.
Good luck and maybe my idea is full of holes
