At approximately {{convert|40|ha|acre}} in extent, it is one of Scotland's largest freshwater islands. The island, which contains the site of an Iron Age fort, can be reached by a wooden road bridge accessed by a track leading from the farm of Dunglass on the west side of the river or across a footbridge that spans a weir at the south-west extremity of the island.[1][2] Following a substantial flood in 1892, Nairne described the island as follows:[3] Port of Dunglass farm, about {{convert|100|acres|0|abbr=on}}, consists of Dunglass Island in the river and the embankment here broke, with the result that over twenty acres was covered with a thick layer of gravel that renders it unfit for further tillage. The Conon channel used to be the larger of the two but a gravel bank was thrown across above the Islands, and the greatest part of the river, for a time flowed through the Dunglass channel. The diversion of the river caused enormous damage to salmon ova, as the breeding banks were left dry, and something like a million ova practically became useless. In 2004, a £38,000 biodiversity project involving Scottish Natural Heritage, Conon District Salmon Fishery Board, Brahan Estates, the Highland Council and Ross and Cromarty Enterprise was undertaken. Dense plantation woodland was removed and {{convert|400|t|LT}} of cobblestones repositioned to aid salmon spawning, which also benefited other river species such as lampreys.[4] This work restored an alder-lined channel through the island, which had become "defunct".[5][6] Notes1. ^1 {{Ordnance Survey}} {{Commons cat|Dunglass Island}}{{coord|57|33|26|N|4|26|58|W|region:GB_type:isle|display=title}}{{Islands of Scotland}}2. ^"Dunglass Island and the Conon, Maryburgh" walkhighlands.co.uk.
