I need help figuring out a way to control sediment and silt pollution in my pond. Every time a hard rain comes a lot of sediment is washed into my pond from a stream (which is also fed by road runoff). I have a pretty large marshy/bog area but very few plants (looks to have a lot of iron in the soil). What can I plant that will help purify the water going into my pond as well as filter out the sediment? What about structures to help control. Not looking to build a lot of stuff that requires maintenance or spend a ton of money. Can I plant cattails and willows and stuff like that to help out?

I have an area of land that is either under water or soggy most of the year. I live in the south eastern United States in zone 8. The soil looks to contain iron. There is runoff coming in at 2 different spots and meeting up before flowing into my pond. There is a lot of silt run off into the pond that I would like to stop. I would like to apply permaculture principles to the piece of property growing plants that are edible, useful, medicinal, habitat, etc. Not sure if I can do all but not sure where to begin.
