Newbie here that is strongly considering building an 1/2 acre pond in Central Illinois. We have a natural spot to place a pond centered along an existing ditch that has some small springs leaking along the sides (approx 6ft below ground level). We dug a test hole and did find some gravel but that didn't seem to bother the gentleman that dug the test hole.

Add to this we have what I call yellow clay, so I'm concerned about all the comments about springs causing leaking issues. My pond builder sees no issues, but I am concerned.


Also is there any guidelines as to what it costs to build a pond of this size? He is offering to do it for under 10k.

I apologize if this is in the wrong area.

Thanks in advance for your help!
