On April 16, 1970, the Navajo Agricultural Products Industry (NAPI) was developed by the Navajo Nation Council as an enterprise to operate Navajo Indian Irrigation Project (NIIP). The Navajo Nation Council not only created this enterprise to assist NIIP, but to create economic opportunities for the Navajo people and to build a foundation of commitment, pride, and dedication to their nation.
From past to present, the Navajo people have maintained their existence and built upon creating NAPI to operate and benefit the people and the business.
Navajo Indian Irrigation Project
Legislation PL 87-483 | Authorized June 13, 1962
The Navajo Tribe traded their water rights for the construction of the Navajo Indian Irrigation Project. The objective of NIIP is to irrigate 110,630 acres farmland. Navajo Lake is the storage reservoir for approximately 508,000 acre-feet of annual allocated water to irrigate the NAPI farm at full build-out of Blocks 1 through 11.
NIIP’s development is broken into 11 Blocks, with approximately 10,000 acres in each block. Block 1 was first irrigated in 1976, Block 8 started irrigating in 2002. Currently, 8 Blocks have been completed & Block 9 has approximately 1000 irrigated acres. The project completion is dependent upon moratorium.

The diversion of over 109,000 acre feet of water annually from the San Juan Basin into the Rio Grande Basin has provided additional municipal and industrial water to cities on the Rio Grande, from Los Alamos to El Paso. This diverted water is the water right that the Navajo Nation traded for construction of the Navajo Indian Irrigation Project.
On April 16, 1970, the Navajo Tribe created an enterprise with the day-to-day responsibility to operate the farm. That enterprise is the Navajo Agricultural Products Industry, NAPI.
