Pond Boss Forums INTRO Questions & Observations neighbor installed field drain tile *frowns*

Has the drain tile caused the watershed of your pond to increase? ie water that was previously flowing into some other valley now flows into your drainage area?

Are there terraces in the field? Does the drain tile have risers (water inlets) out in the field in the terrace pans? Most drain tile outlets I have seen have relatively clear water coming out since the water is filtered though several feet of soil before entering the pipe.

sounds like you definitely need to visit with the neighbor.
