Ian Strathcarron has identified what was El Yuba Dam as Odem, in the Golan Heights.
Sam and the pilgrims were warned by their dragoman not to stop and ask for water at this location. The Quaker City Itinerary places the date for this as September 17, traveling from Kefr Hauwar to Baniyas.

I've plotted the location of the Odem Mountain Winery, which according to Ian Strathcarron, is located at this site.
