I have a new 1.5 acre pond in Iowa and want to try and prevent silt from the neighbor farmer's 70 acres from accumulating in my pond over time. I am considering building a 10 foot long rock "Dam" out of clean 3 inch rock that would be deeper than the creek that feeds the pond. My hope is the water entering the pond will deposit any sediment prior to entering the pond.

Should I be concerned about silt with the ratio of watershed compared to my pond size? Would the plan be effective? Building an actual silt pond would be ideal, but the lay of the land would make that difficult.
