Template:Irrigation

Irrigation requires at a minimum a tile of, a Noria, and a Reservoir.

Fresh water can be moved a maximum of 24 tiles by a Noria through any combination of Aqueducts and Reservoirs. A Reservoir built in the 17th tiles provides irrigation.

A Noria can push water in three directions and the 24 tile limit applies to all combinations of directions. For example, a Noria can push water a total of 8 tiles in any 3 directions and have working Reservoirs in the 9th tiles. If a Noria pushes water in three directions, it can push water a maximum of 8 tiles to each side and 9 tiles in front with working Reservoirs in the 9th tile on the sides and the 9th tile in front.

A correctly operated Reservoir applies the 'irrigated' status to any land tiles:
 * You can build a Farm or Orchard on, although the irrigated Barren land tiles don't provide a Fertility bonus
 * Farms get a + bonus
 * Orchards get a + bonus (+1 Food per tile)

The irrigated status does not stack with several reservoirs, but the irrigation status does stack with the Farm production bonus from Windmills.
