Is there a way to calculate the percentage (or length) of a stream network that is multiple channel streams?

I have a polyline stream network of all channels within a drainage basin (which is 1.1 million square km) A number of the rivers in the basin alternate between single thread and multichannel (i.e. anabranching or braiding).

Is there a way using argis for me to calculate the length or percentage of total which are either multi or single thread, without simply measuring the along line distances?

The ideal end product would be two values:

  1. percentage (or total length) multichannel
  2. percentage (or total length) single channel
