Loch Knockie (see Plate XCI.). A loch of moderate size and very 

 irregular form, about a mile east of Loch Ness, opposite Invermoriston. 

 It is a beautiful loch, with great parts of the shores wooded, and several 

 tree-clad islands (see Fig. 63). It is narrow, with the axis running 

 nearly south-west and north-east. The shore-line is undulating. A

large broad bay runs off to the north-west, and there are several smaller 

 bays on the south-east shore. The length is 1J miles, the maximum 

 breadth half a mile, and the mean breadth one-fifth of a mile. 



The superficial area is about 182 acres, or a little over a quarter of a 

 square mile, and the volume of water 194 millions of cubic feet. It has 

 a very limited drainage area, amounting to only about 1 square miles. 

 No large stream flows into it, and a short burn carries the overflow into 

 Loch nan Lann. There is no bench-mark near, but a spot-level on the 

 shore indicates that the loch is a few feet less than 700 feet above the 



sea. 



Loch Knockie is on the whole shallow, as indicated by the low mean
