[Mithadan]

When I wrote Tales from Tol Eressea, now about 20 years ago, I did study BolT and JRRT's later works in an attempt to divine the island's geography. Unfortunately, all that is mentioned post-Bolt is the city and port of Avallone on the eastern side of the island and the Mindon in that city. While I included Tavrobel in my Tales, there is nothing after BoLT that mentions that town (with the possible exception of the Etymologies and the first Quenta, both dating back to the 1930s, and the poem from the 1920s). Nor is there any clear mention of any other places, such as the rivers I recall being mentioned, in Eressea post-Bolt.

I am working from memory so others may have more information.
