When the arrangements were agreed in 1945 for incorporating this stretch of river into the Tummel-Garry Hydro-Electric Scheme, there was no provision for any hands off flow to be maintained and a weir was put in place to prevent salmon gaining access.
In recent years, the implementation of the Water Framework Directive provided a stimulus for the balance between the costs to SSE of re-engineering structures and losing some hydro generation and the benefits to the environment, to be re-examined, and a flow has now been restored and access to salmon reopened. SSE, SEPA and the Tay District Salmon Fisheries Board have needed to work together to reach this successful outcome which was marked by a celebratory event which local and national organisations attended on 30 October.
The Tay District Salmon Fisheries Board (Tay DSFB) is anticipating that as many as 1500 extra salmon might pass the fish counter at Pitlochry Dam further downstream once the opened up water is fully colonised.
