Is artificial irrigation used for growing grain in the US in any meaningful amount? Rain falling on crops shouldn't count towards "water usage", since the rain would just fall on other plants (e.g., grass or trees) in absence of farming.

Table 32 here breaks it down:

There is substantial irrigation of grains but the majority of grain acres are not irrigated.
