Cutting topographic data below a polyline

Context: I want to cut  *.xyz data for a river channel below the free surface. 

 

I assume I want to use ArcGIS to generate a polyline based on my free surface data, and to clip out all topographic data that exceeds it. However, this isn't a method I've used before and it's been a long time since I've used ArcGIS. I've not found a method online either. Does anyone know where I could start, or what tools would be applicable?

 

Thanks in advance!
