I am near a lot of reservoirs in California. The main river channel always has creek arms and other coves, and these have names the fisherman refer to.

 

However, I am never seeing these names published on the Navionics maps.

 

Is this normal? Are they ever going to add this? This seems crazy to not label creek arms/etc. 

 

See attached screenshot for example. 

Some are right, some aren't.  I tend to prefer using google earth or maps, and see what they have for names.

Naming the coves would be invaluable
