What is the best method for getting lowpoints? I want to simply show the places on a map that are lower then other parts so i can see where a heavy rain would accumulate.

 

Is "Flow accumulation" the best tool to work? is any other method better?

If you know the terrain statistics, why not just classify the DEM? Use a single color ramp from low to high for the elevation classes. Symbolize the lowest class in a different color then the others.

I might have been over thinking this challange. I have thought about your idea and I can see how it could work well to visualize what I want to show. I might use that method.   Thank you David.
