KDO...a pretty good rule of thumb is having 20% of the pond naturally vegetated and an additional 20% of stucture placed in ways that provide habitat and pathways to travel, while also giving ambush/ fishing channels.
One of our members, AaronM, created a smaller pond that supports well over 2000 pounds of fish in about .1 acres in Pheonix, Az of all places. He created a natural "Bog" system to filter the water and remove nutrients, ammonia, etc. Your planned stream may be ideal for this and also create a truly impressive aesthetic value to the place.
