After reading through several other threads about spring-fed ponds vs. groundwater ponds, I've come to think my builder was incorrect saying ours was spring-fed. From one of the threads, I take it a true spring-fed pond will continuously fill the pond so water will be going through the pipe or over a spillway. When ours was dug, water did start seeping into it, but it hasn't "filled" it up and the water lever only rises after a hard rain. It's still about four feet below the spillway. Our area seems to have a high water table (if that makes sense), as we had to install a sump pump in our basement that runs regularly, and there are a few very "leaky" front yards down the street from us. What are some things I should watch for, given its really not a spring-fed pond?
