if the tile went thru the pond the low draining side of tile should have been cut by the dam core. and if that is the case it is no worries.

the tile you see is presumably the one draining into the pond then. (it flowed) it should have a critter guard installed on the end. preferably this tile should outlet above the level of your pond.

i am concerned that your pond is a couple of years old and has not filled....
