The Loch Davan area is situated in an area of the River Dee catchment known as the Muir of Dinnet. The Muir of Dinnet (area 2287ha) is an SSSI and a Natural Nature Reserve designated because of its value as a habitat for flora and fauna, and important geomorphological features. The Muir forms the south-western corner of the Howe of Cromar, a wide saucer shaped plain at the foot of the Grampian Mountains. The landscape of the area was moulded by gravel and meltwater in the post-glacial era, and the Loch is a kettlehole (ice depression) surrounded by fluvio-glacial hummocks, ridges and hollows. The Loch Davan area is contiguous with the Loch Kinord area and the two lochs are adjacent. Loch Kinord (area 79.0 ha) is oligotrophic whereas Loch Davan (31.1 ha) is mesotrophic with recent research suggesting a transition towards eutrophication. The difference in trophic status reflects the higher proportion of agricultural land use in the Davan catchment
