From WoWWiki

The Loch is the single most prominent feature of the dwarven territory of Loch Modan. It is the largest body of water on the continent of Khaz Modan, and third in size in the entire known world after the Lordamere and the Darrowmere. Fed by an underground source, the loch was originally much smaller, but more than doubled its size after the dwarves of Khaz Modan built the Stonewrought Dam at the loch's northern end. Three islands and three islets dot the loch's waters, and remnants of the second war can still be found scattered about the bottom.

Trivia

• The fact that The Loch is inhabited by Threshadons may be a reference to the Loch Ness Monster, often described as plesiosaur-like (like Threshadons).
