I guess I don't know if it's from a spring or water table...I don't think pumping is feasible b/c there's no place to pump the water to. I don't want to flood my yard.
How important is it to have steep drop offs, shelves, etc? Can I refine these later after the initial shape is made? Is my assumption correct that you don't want the bottom completely flat with steep sides?? Or will this be ok if I add structure? I have many root balls, deadfalls, and PVC trees waiting. THanks a lot!!
