The opening post is not entirely correct. Building Osiris's temple complex (OTC) does improve the Nilometer by a level but that only increases the flood about half as much. For example, in the Sandbox custom mission, if the Nilometer says no flood without OTC, building OTC raises the Nilometer to poor flood, but the flood only covers 3 tiles from the Nile, compared to 6 tiles that are covered with a poor flood without OTC.
Flood quantity depends on the Nilometer, the maximum distance of a floodplain tile from the Nile, and whether OTC exists. A flood covers those tiles that are no more than a specified fraction of (the maximum floodplain distance plus 1) from the Nile. Without OTC, the fractions are: none=0, poor=.2, mediocre=.4, good=.6, excellent=.8, and perfect=1. If OTC is built, a perfect flood is not changed but for the other levels, the Nilometer increases by a level and the fraction is increased by .1. With OTC, a perfect flood on the Nilometer might not completely cover the floodplain.
I tested all flood levels in five missions (with the maximum floodplain distance): Heh (4), Sauty (20), and the custom missions Henen-nesw (11), NAFTA (15), and Sandbox (29). (In Heh, OTC did not affect the flood at all.)
