The massive pipes that supply the hydro-electric power station drawing water from the River Clyde.
'Waterfall days'
A large hydro-electric power station was built in 1927 to harness the power of the Falls of Clyde. The falls were a key attraction on the site, and when the water volume markedly fell, so did the visitor numbers. The reserve has worked hard over the years to develop other natural attractions, such as the wildlife tours and woodland walks and today visitor numbers are a healthy 60,000 a year. Tourists can still enjoy the natural force of the falls on special 'waterfall days' when Scottish Power turn off the hydroelectric power station. The resulting spectacular cascades have drawn a thousand or more people into the reserve. These events are generally timed to coincide with bank holidays so that more people can appreciate the spectacle.
