Caveats

  • Figures are total acres NASS classifies as irrigated, regardless of what is grown; not a crop-by-crop breakdown.
  • Two of Idaho's 44 counties are withheld for disclosure in 2017 and omitted here rather than estimated.
  • USDA's separate Census of Irrigation and Water Management (2013, 2018, 2023) is a different survey and is not mixed into this series.

Caveats

  • USGS published one county-level file per Circular year (1985, 1990, 1995, 2000, 2005, 2010); Understand Idaho reads each directly from the publisher's site. 2015, the last Circular year, instead comes from a separate USGS data release, linked above.
  • USGS publishes withdrawals in million gallons per day (Mgal/d); values here are converted to acre-feet per year (1 Mgal/d = 1,120.14 acre-feet per year).
  • Idaho statewide and category totals are this site's own sum of the source file's county-level rows, not a separately published state total.
  • Irrigation withdrawals cover crops and, from 2000 on, golf courses, combined into one figure.
  • Livestock is stock watering only; Animal Specialties (1985-1995) and Aquaculture (2000 on) are separate categories because USGS defines them differently. Commercial is a category only from 1985 to 1995; USGS stopped compiling it after 1995.
  • Mining has no figure for 2000; Public Supply (2000), Livestock (2000 on) and Aquaculture (2000 and 2005) are fresh water only.
  • The 1985 file prints zero for Animal Specialties in every Idaho county; the value is stored as printed.
