I'm a little out of bounds, but will toss a few thoughts your way.
Check the pH and alkalinity of your pond. Then, add gypsum in small doses, so as not to dramatically change your pH and alkalinity.
Once you hit the "break point", the water will clear.
Your long term solution is to stop the source of suspended soils.
By the way, continue feeding the trout. They feed by conditioning and smell as much as by sight.
If you feed them, they will come.
