Length of the main stem in a river by summarizing line segments

I have a problem with calculating the length of the main river in a network of rivers. I am only interested in the main stem length. Problem is that the river only consists of line segments and many side-rivers I am not interested in. Do I have to calculate this manually by using the "Identify" tool or are there easier options? I am going to use this on many different rivers so I hope there are more efficient ways to sort this out. If so, can you give me a little guide or point me in the right direction?

Help will be appriciated

At least by using the Strahler method of stream ordering and other tools


it will simplify what you consider to the the main stream channel then you can select the segments and get their length
