Pitlochry fish ladder

Although viewing the ladder is still allowed, the observation tank as of July 2019 has been closed due to "access and safety concerns".

The ladder was constructed as a result of a 1943 Act of Parliament which laid a duty of care on the North of Scotland Hydro-Electric Board to preserve fish stocks in the waterways encompassing its power schemes.

[2] The fish ladder consists of 34 separate pools, each 50 centimetres (1.6 ft) higher than the last and covering a distance of 310 metres (340 yd).

[4] There are three larger pools which allow the fish to rest during their ascent, and one of these has an underwater viewing area with a glass wall and CCTV cameras to allow the public to observe the fish making their climb during the breeding season.

An average figure has been nearer to 4,000 fish, looking at the Tay District Salmon Fisheries Board report of 2015.
