To get water out of the creek and into the ditch, several things are needed where the ditch begins.
- A diversion dam keeps a constant water level at the headgate, so that a set amount of water will always be available to the ditch intake.
- The headgate structure and trash rack keep excess water, branches and trash out of the ditch.
- The headgate valve regulates the amount of water flowing into the ditch. It is chained and padlocked in position, so it cannot be tampered with.
- The spillway allows excess water to return to the creek.
