Headgates

Gate lift wheel

It took a lot of muscle to turn this wheel! As the gate lift wheel was manually turned, the gate lifted from beneath the windscreens and blocked off the entrance to the forebay.

Gate lift auto starter

The gate lift auto starter was powered by direct current electricity. It replaced the manually operated wheel that lifted the headgates.

Gate gauge

The gate gauge monitored how high the headgates were raised. Each gate could be raised to approximately five meters (16 feet) to allow water into the penstocks.
