After passing through a heavily wooded area[4] it reaches a tall concrete dam with a control centre, which is labelled "pumping station" on maps.

It is crossed by two bridges carrying a local road to the hamlet of Kilmichael Glassary (Gleann Cill Mhicheil Glas-Airigh).

Between the bridges, it is joined on its right bank by Allt Slochd an Ime, which drains the foothills of Creag Buireinich.

[4] The river is crossed by a small bridge, providing access to Dunadd fort, which is situated on a rocky outcrop on the left bank of the channel.

It is a scheduled monument, and is thought to have been the capital of the early Scottish kingdom of Dál Riata.

Here it is surrounded by the bog fields on the Mòine Mhòr Nature Reserve, and becomes tidal below the Kilmartin Burn confluence.
