2 acres? Small Lake, not a pond,lol Installed many myself. 1st, is pretty good size job.But you could do it with a good excavator or loader and a good dozer though. Keep in mind if hiring out, roughly 60.00 an hour. Have questions, electric near pond? For trout you would want good clean water, some sort of filtration, a skimmer pump with filtration basket works well and also keeps water moving. 2 acres is good size, maybe want a couple of these. Also may think of a bubbler for winter and an aerator for warm months If no electric, Bass, Gills, etc, any warm water fish should do well at that depth. There are many fish freindly chemicals to control weed growth. Could house many fish in a 2 acre pond, suggest 20-30 to start. Wait a good week after fill to let settle. Will you install liner? There are many out there. We used one this last year that was more like a tyvec house wrap as apposed to a rubber liner. Tough stuff and a little less costly.Suggest a ledge ten feet out from edge of pond 4 to 6 feet deep then dig out center. Leave edge out of one end for exit with dirt.
I am in no way an expert, just been around it for many years. Best of luck and if I can be of any further help, let me know, will surely try.
