Southlake Moor (grid reference ST370300) is a biological Site of Special Scientific Interest (SSSI) near Burrow Mump and Burrowbridge in Somerset, England.

Regular signs of the otter are seen on the muddy banks of the River Parrett.

The ditches on the east side of the site contain a population of the palmate newt.

[1] During 2009 and 2010 work was undertaken to upgrade sluice gates, watercourses and culverts to enable seasonal flooding during the winter diverting water from the Sowy River onto the moor.

It has the capacity to hold 1.2 million cubic metres as part of a scheme by the Parrett Internal Drainage Board to restore ten floodplains in Somerset.
