We just had our pond dug last fall - it is about a 1/8 to 1/4 acre and steep sides with a max depth of 15-18 ft. It is heavy heavy clay soil and there is run off from a large area (about an acre) that is much higher than the pond itself , this run off is ditched into the pond, but there is what I believe to be a lot of iron bacteria in this run off and it is running into the pond. Question, is there anything we can put at that inlet to capture that before it goes into the pond or do we need to re-divert that runoff to not go into the pond. It is a very low flow and I would expect it to dry up in later in the summer - maybe. The area above is all the clay that was dug out to make the pond.
