- Cut the power to the transformer yard.
- Truly, you are the master of floodgates.
This achievement is story-related and cannot be missed. There is a fairly simple floodgate puzzle near the middle of The Clicker to complete at the Bright Falls power plant for Cynthia Weaver. After closing all of the floodgates, traverse them and flip a switch to turn off the power to the transformer yard on the opposite side of the river, and this will earn you the achievement.
