Double Floodgate

The Double Floodgate is a building used to control water flow in irrigation and dam systems. It functions like a two-tile-high adjustable barrier: its control sets a target water height between 0 and 2 (meters) in precise increments, and water above that level will spill over while water at or below that level will not pass through the structure. This makes it suitable for creating stepped spillways, managing reservoir levels, or forming controlled overflows where a single floodgate's height is insufficient.

The height control is granular, adjustable in 0.05 increments, allowing fine tuning of water behavior around the gate. By default, adjacent Floodgates have their heights synchronized, so a line of gates will automatically match each other unless you disable that option—useful for making even dam faces or continuous weirs without individually adjusting each unit. Because the unit prevents percolation above the set level, it effectively forms a waterproof barrier up to the chosen height while permitting overflow once that height is exceeded.

Practical notes:

• Use Double Floodgates when you need a taller adjustable overflow than a single gate provides; stack or place them to shape stepped drops.
• Disable synchronization only when you intentionally want different heights on neighboring gates (for staggered spillways or stepped terraces).
• Fine 0.05 increments let you balance reservoirs precisely, but remember that water physics and inflow rates still affect actual behavior—monitor upstream/downstream levels after adjustments.
• The building is categorized with Floodgates and Dams and is commonly used in conjunction with channels, reservoirs, and pumps to create robust water-management systems.
