Selecting only canals that are connected to reservoirs?

I have a polygon layer of water reservoirs and a polyline layer of canals.

In my data, some canals are originating from reservoirs, and leading to other canals. On the other hand there are some canals that are isolated or not connected to anything. (How this came about is story for another day)

I need to delete the isolated canals and those canal networks(i.e. connected set of canals) that are not connected to a reservoir.

I assume that i will have to use some kind of network tracing, but I am not sure where to start.

I have ArcGIS desktop, along with Network Analyst to solve this task.

How would you go about this task?
