Lake Sediment as Soil Amendment?

Asked November 19, 2020, 3:17 PM EST

Has anybody ever dredged a lake and used the sediments as a soil amendment? Was it a good idea or a bad one? Is there someone who could test the dredging materials on a small sample size and determine the composition of the stuff?

Thanks in advance,

Thank you for your question, Clarlie. There has been quite a lot of research on this topic, largely by the EPA. Here is another one: What contaminants are in the sediment depends upon runoff, trash dumped in the lake, and natural erosion conditions. Here is an OSU publication listing available labs: This can be relatively expensive and, as the second article mentions, may cause more harm than good to your soil, even if free of environmental hazards. I hope this is helpful. Good luck!
