So from what I've learned (not a professional just a curious person) it's better to feed the source because a drought affected area given a sudden burst of water will flood instantly. The ground is too dry to properly flow the water so it just sits on top which is typically what causes a flash flood. So feeding it to the source would allow it to actually distribute the water at an even pace without causing a sudden flood
