Muckle Water

Muckle Water is a long, narrow fresh water loch on Ward Hill on Rousay, Orkney, Scotland. It is the biggest loch on the island and is popular for fishing. It can be reached by a track from the roadside. The Suso Burn on the north eastern shore drains the loch into the Sound of Rousay. A rare hybrid pondweed (Potamogeton sp.) is found in the loch as a result of its unique nutrient levels. The loch was surveyed in 1906 by James Murray and later charted as part of The Bathymetrical Survey of Fresh-Water Lochs of Scotland 1897–1909.
