Consider using a small sediment pond upstream of your inflow to settle out particulates. Some members here have built them to great success but obviously the location-specific details matter quite a bit. Can you find a real pond builder (not just a dirt guy) to help you?
Once I get serious, I plan on getting several quotes, including some from a "real pond builder". My money has been going to other directions this first year. (fencing, gates, cleanup, driveway, etc...)
I'm still in the brainstorming phase at this point! For now, I plan on deer hunting the creek bottom and hopeful one day to catch a bass off the same creek!
