You can download a beat map of the River Carron near here. I am not sure if this is given out with permits or not but it seems to be something many anglers have found useful in the past and I only found a copy in a very old link on a rather unused forum somewhere, yet clearly people still look for this kind of info. The map was created by Roger Geary (see comments below) and the official up to date version of the file (in jpg format)  can be found on the MediaFire platform at this location.

This file is in JPG  format and is just over 1.2Meg to download.
