Saturday 29 September 1pm-3pm.
Volunteers from Torrs Hydro will be on site to answer your questions about the project.
Find out what goes on behind the scenes, walk down the fish pass and see inside the engine house.
I will also be around to talk about the inspiration for the Junkstop installation - 'Message In A Bottle' - created specifically for the site with New Mills School Art Department.
The eyes are watching you!
