Creating inset shadow for river polygon in ArcGIS Desktop?

Question

I'm trying to accomplish what the image of the two ponds shows as "inset" shading. They called this Bevel effect, which I think was down in Adobe Illustrator. I'm using ArcMap 10.3 without 3D Analyst.

I want to shade a river polygon so it ultimately appears as if it's at a lower elevation then the ground. The closest I've come to that is creating a buffer around it using the Buffer wizard (see image with shaded rivers).

I've also used the move tool through the Layer Properties menu --> Representations. However, this only makes the polygon appear to pop up.

You can do something close using the following steps especially for the first image:

• Go to layer properties of the lake symbol -> Symbology
• Click on the Symbol (Colored Rectangle) to change its properties, as you can see below:

• Click on Edit Symbol -> Under Properties Type Choose Gradient Fill Symbol, as you can see below:

• Right-click Color Ramp -> Select Properties -> Choose the desired two colors that you want -> Adjust the Bright and Dark colors to get the desired effects
• Press OK (3 times) -> Apply and you can get an output like this:
