Loch Castle

It's clear that the existence of Lochmaben Castle, on the banks of this unknown lake, has been a definite factor in the lake's name, Castle Lake (Loch Castle). The most popular explanation (according to the area's historical records), was to say "Let's go to castle lake", so this denomination was established as the official name. This is interesting, since the castle is called Lake (Lochmaben) and the like is called the castle. Today, the lake is part of the nature reserve surrounding Dumfries and is popular among fishermen because it's full of fish, so you'll find several companies that rent boats and fishing licenses.
