Box Elder Irrigation
← Bear River dashboard · Canals · BRWCD · Box Elder Irrigation · Brigham City Irrigation
The dashboard labels this diversion "Box Elder Irrigation District (BRID)." No single "Box Elder Irrigation District" exists. Box Elder's irrigation is carried out by many separate canal and ditch companies, not one district. The dashboard's "BRID" is a generic label for the Box Elder Valley's irrigation as a whole — and it substantially overlaps with the canals diversion, which describes the same physical system.
This page exists to be straight about that: of the four diversions on the dashboard, "BRID" is the one whose name is most clearly a model construct rather than a real entity.
Where the water goes
Across the Box Elder Valley — the irrigated farmland on the valley floor and the foothills around Brigham City, Corinne, Tremonton, and the surrounding communities of northwestern Utah. The water comes from the Bear River and is moved across the fields by the region's canals, laterals, and ditches.
What it is used for
Irrigation of crops and forage — the same uses as the canals: alfalfa and hay, pasture, and row crops. The Box Elder Valley is one of Utah's most productive agricultural regions, and its farm economy depends on this water.
Why this overlaps with "canals." The dashboard splits the valley's irrigation into three sliders — canals (280,000), BRID (110,000), and BCID (70,000) — for 460,000 acre-feet/year of irrigation in total. But there is no three-way physical division of the valley's canals that matches these three labels. The three sliders are arbitrary buckets of one system (the Box Elder canal and ditch network), created so the what-if dashboard can let you drag irrigation up and down in parts. If you are trying to map a slider to a real, named operator, "BRID" is the one that will not map cleanly.
Who holds the rights and operates it
Because there is no single district, there is no single operator. The water is held and operated by the dozens of independent mutual canal and ditch companies of Box Elder County (the same ones described on the canals page). Each is owned by the farmers and landowners it serves, and each holds water rights with priority dates that determine who is served first in a shortage.
If a single "BRID" did exist, it would be a water users association or irrigation district — the kind of entity that consolidates many small ditch owners under one management. But the state's canal registry shows Box Elder as a patchwork of separate companies, so the dashboard's "district" is a fiction for modeling purposes.
How it is monitored and regulated
- Self-reporting by the individual canal and ditch companies to the state.
- Utah DWR regulates the companies, administers the water rights, and publishes the water-use accounting (the Box Elder area appears as the Brigham City and Corinne sub-areas).
- USGS gauges (Corinne 10126000, below-O-Line 10126050) measure the river's overall loss across the valley — the closest independent check on total irrigation take.
- As an interstate river, the Bear River's allocation is also governed by compact and settlement agreements with Idaho and Wyoming.
Is any of it wasted?
The same analysis as the canals applies, because it is the same water and the same fields:
- Flood and furrow irrigation loses a large share of applied water to evaporation, seepage, and runoff rather than crop uptake — "waste" by the engineering definition.
- Some of that loss is beneficial (groundwater recharge, return flow), and Utah's push toward efficiency and secondary metering aims to convert "diverted but wasted" into "diverted and used."
- At the basin scale, agriculture is the dominant use (~63% of Bear River basin water per the 2016 USU white paper), so efficiency here is the biggest lever for the river and the lake.
The specific "waste" concern for a district-level label like BRID is that it hides the variation: some Box Elder operators have modernized to pivots and drip, while others still flood-irrigate. A single "BRID" number cannot show that spread.
The dashboard number
The dashboard assigns 110,000 acre-feet/year to "BRID." This is a modeled estimate, not a measured figure for any real entity — because no such entity exists. It is one of three arbitrary buckets the dashboard uses to represent the valley's ~460,000 acre-feet/year of irrigation. Do not read it as the take of a specific "Box Elder Irrigation District."
For scale: the DWR's water-use accounting puts the Brigham City sub-area at about 147,600 acre-feet/year of surface agricultural diversion (1989–2024 mean) — one sub-area, already larger than this single "BRID" bucket, which is a sign the buckets are a modeling convenience rather than a census of real operators.

Data gaps
- No real entity to document. The honest finding is that "BRID" is a model label. The underlying reality (the Box Elder canal system) is documented on the canals page.
- The three-way irrigation split (canals / BRID / BCID) has no physical basis in the sources found; it appears to be a dashboard modeling choice.
- Per-company diversion totals are not publicly aggregated in a form the pipeline can read.
