228 THE FRESH-WATER LOCHS OF SCOTLAND 
Lochenbreck Loch has a rhomboidal outline, each side being about 
a quarter of a mile long. It is situated at an elevation of 651 feet 
above sea-level, about seven miles N.N.E. from Gatehouse of Fleet, 
and has the characteristic features of a bare highland loch, modified 
by a plantation of coniferous trees on its eastern shore. The shores 
are stony, and the water is clear and slightly peaty. The flora is of 
the ordinary type, excepting an abundance of Heleocharis multicaulis. 
Woodhall Loch is three miles north-east of the last-mentioned. 
It is If miles long by J mile broad, at an elevation of 173 feet 
above sea-level. Being somewhat wind-sheltered by low hills and 
surrounded by meadow, grassy moor, or deciduous wood, it presents 
the general features of a lowland loch, saving that its water is very 
slightly peaty. Here and there a gravelly bay occurs, but frequently 
the moor or meadow-land abuts upon the water without the interven- 
tion of a shore. Where a strip of shore does occur, it is narrow, 
stony, and frequently covered with Juncus articulatus. The west side 
has a reedy or sedgy margin almost continuous throughout its length, 
but on the east side the reeds are mostly restricted to the bays. At 
either end there are large associations of Equisetum limosum ; the 
specimens of this plant at the north end are very large, rising 
3 or 4 feet out of water 6 feet deep. The bottom of this loch, from 
a depth of about 8 feet to the deepest part, is covered with the dead 
remains of vegetation, which prevents the growth of plants upon the 
bottom at a greater depth than 8 feet. 
At some parts of this loch the following successive zones of plant 
associations were observed, starting from the shore : — (1) Juncus effusus, 
J. lamprocarpus, J. acutiflorus, and Ranunculus Flammula, all more 
or less mixed ; (2) Carex rostrata or C. filiformis ; (3) Heleocharis 
palustris ; (4) Phragmites communis ; (5) Equisetum limosum ; (6) 
Scirpus lacustris ; (7) Potamogeton natans, P. polygonifolius, and P. 
lucens, mixed ; (8) Nvmphaea lutea, Castalia speciosa, and Potamogeton 
natans, mixed; (9) carpeting the bottom below these zones, wherever 
I here was space, Lobelia Dortmanna and Littorella lacustris. 
This loch forms a somewhat transitional stage between a typical 
peaty highland loch and a typical lowland one. 
Blate's Mill Loch is a small circular pool within a few hundreds 
of yards of the east shore of Woodhall Loch. It is surrounded with 
a zone of Carex rostrata and Equisetum limosum, with quantities of 
Nymphasa lutea, Castalia speciosa, and other plants common to the 
district. 
Mossdale Loch is a peaty pool half a mile from New Galloway 
railway station. It contains a few plants common to the neighbour- 
hood, but, like the last-mentioned, appears to be of no further 
botanical interest.
