Class I equivalency

The amount of less productive land in a water district receiving Bureau of Reclamation water (Classes 2, 3, and 4) that would be necessary to be equivalent in productive potential to Class I land. This equivalency rating is made to adjust the number of acres that may be irrigated (see acreage limitation) so that less productive lands are equivalent in productive potential to 960 acres of Class I land.
