Beastman, my pond has runoff from both row crops and cattle. I wish I had a settling pond. I was too eager for more fishable water. I have had issues with FA in past years. This year the FA was almost nil, but did have very green water with only a few inches of visibility this year. No fish kills or anything, but worrisome.

If you can get a sediment - prefilter pond that the run off hits first to slow it down, you may have less problems with nutrient loading later.

Btw, the cattle and row crops are not mine, so I have no control over tillage and feeding or fertilization methods/times. You may have more input with your situation.
