Salmon Traffic Light System shows promise as salmon are endangered; Blairgowrie is cited in conservation efforts coordinating with businesses to shield the migratory young. Blairgowrie, Perth and Kinross, is a Scottish town increasingly framed in environmental safeguards.
The Tay Rivers Trust has completed a second year with no smolt mortality at Blairgowrie weirs, using a traffic-light system to guide water abstraction during low-flow periods. Local businesses voluntarily reduce intake during red periods and gates can open to bypass the weirs, boosting river flow for endangered salmon.
