This is the River Findhorn, the Nairn being the next one north. It is Dulsie Bridge however and interestingly during the "Muckle Spate" of 1829 the river level reached just about where the photographers feet are in this photo! There is a nice shot to be had of the River Nairn from the road bridge at Clava just off Culloden Moor, it is most attractive in autumn colours and I imagine this shot would work well in autumn as well.
