Please follow from 2:54. After you create the flow accumulation raster go to properties and in symbology you can check which value will work for you.

@@harisfaheem5859 If i could send you some pictures it would be more clear for you. Let me try. Please create the flow accumulation raster again. Then goto symbology. Go-to classified. Select first range colour as black. And all others in red. And if you want to create two class then observe the lowest value in the ranges. And as I entered 500 you try with the lowest value. The lowest value will be the 2nd class's first range value Number. Please try it

Thank you. Before the dissolve step we created polyline(stream to feature). Open attribute table for this file. And right click in grid code and go to statistics. You will find stream numbers there.

Cells with a high flow accumulation are areas of concentrated flow are used to identify stream channels. I choose 500 because all cells with more than 500 cells flowing into them are assigned with different value, and all other cells are assigned NoData. For future processing, it is important that the stream network, a set of raster linear features, be represented as values on a background of NoData.
