Liminological Shipping Routes (WIP)

[inspectorjavert]

So this is a part of the lore I'm making as part of my world building. This is a map of Dragon Lake, the largest lake in the known portion of my world. It serves to major purposes for the people in my world. First it has a very high fish population and fishing boats routinely travel the lake, fishing during the morning and afternoons when the fish feed, and moving to the islands in the lake to mine salt from the rock formations there in the evenings. The salt is used to preserve the fish, which are sold at the nearest port when the ship has either filled its holds, or decided to cut its losses.

The second purpose of the lake is to serve as a shipping hub, an ancient civilization built very complex canals on both ends of the lake which grant access to the "not" Mediterranean sea and a major inland river from the lake. So what do you think of my map and the lore I've written behind it?

Thanks in advance.

EDIT: You know what would have been really awesome? If I remembered to add my attachments when I posted something.
