The Earl of Dumfries proposed to make a 'cut' from the River Nith in New Cumnock through the Loch o' th' Lowes and Creoch Loch to the Black Loch in order to provide a supply of water to power a factory he intended to build on the Glaisnock Water.
This would have resulted in part of the waters of the River Nith flowing onto the Clyde rather than the Solway, however the development was never carried to fruition.

Fanciful imagination has pictured a trout swimming up the River Ayr, passing into the Lugar Water at Barskimming, entering the Black Loch via the Glaisnock Water and thence into the Black Loch.
The second outflow from the loch would carry the trout into Creoch Loch, then into the Loch o' th' Lowes, the River Nith and finally into the Solway Firth after a journey of around seventy miles.

The 1864 OS map shows the main line railway cutting between Black Loch and Creoch Loch, running from the east to the western lochshore of Creoch Loch.
