How can Utah ensure enough water to both municipalities and farmers?

Background

Background 2

In 2022, a study published in Nature stated that “2000-2021 was the driest 22 year period since at least 800.” (Nature) As water demand increases and droughts continue throughout the Southwest, maintaining water in major waterways has become difficult. This has been especially taxing on the Colorado River, which supposedly provides 17.5 acre feet of water to the Southwestern United States each year. Unfortunately, the river has only been able to provide 10 million acre feet of water per year for the past couple years (NYTimes). As the river's flow has declined, allocating water has become more difficult, and the federal government is beginning to mandate that certain states begin to conserve more water (doi). States are arguing amongst themselves who legally has to take the cuts in water allotment. The Upper Basin (Colorado, New Mexico, Utah, and Wyoming) argue that they can’t make many more cuts. As the negotiator for New Mexico says, “...the lion’s share of what needs to be done has to be done by the lower basin states.” (NYTimes) While Arizona, California, and Nevada most definitely need to make major reductions in water use, the Colorado belongs to all of us, so we must all do our part. As Lady Bird Johnson eloquently puts it, “The environment is where we all meet; where we all have a mutual interest; it is the one thing all of us share.”

Additionally, we have our own personal troubles to consider. In 2022, the Great Salt Lake reached the lowest levels ever recorded, (dwr) only 45% of the level twenty years prior. (me) The main tributaries to the Great Salt Lake are the Bear and Jordan Rivers, whose annual streamflow has been steadily declining since 1980 (University of Utah).

Agricultural

Water Use

On average, Utah has used ___ KAF of water for agriculture from 20__ to 20__ (U of U). However, this amount is highly variable. Insert Graph. I took water data from the U of U and crop production data from Utah Agricultural Statistics and Summary Report from the Utah Department of Agriculture and Food to analyze water yield vs. production. Fruit production is ignored as it is super small compared to crops. Additionally, as Utah is a cold desert biome, summer precipitation is ignored as it is minimal.

Figure 1:

As seen in Figure 1, as water depletion increases, crop yield does not necessarily increase. In fact, in three out of four crops, yield decreased as water increased. However, it should be noted that r^2 values are incredibly small. At most, 11% of the variance in the data is accounted for by change in water depletion. This tells us that water depletion does not play a significant role in crop yield. So, in theory, we can potentially decrease up to 20.6% of our agricultural water use and maintain the same yield. Alternatively, we could mandate only x acre feet/ acre of x crop is allowed to be used.

Water Conservation

SB 18

On March 13, 2024, the Utah legislature passed Senate Bill 18, which enables farmers to sell or temporarily “rent” water to the Great Salt Lake that they have conserved from water-saving technologies. This shifts the “use it or lose it” water right policy that has previously been the mentality of farmers throughout the state. However, it should be noted that this bill does not specifically give water to the Great Salt Lake. Additionally, water tracking is difficult and allocating these water rights will not be easy. Water tracking meters throughout the state are outdated (Scotty). Money will need to be invested to bring these up to date.

Agricultural Water Optimization Project

In 2019, Utah started the Agricultural Water Optimization Project (AWOP). It has invested $73, 441,375 in 369 farms costing a total of $195,990,601. In total, they have saved 170 KAF/year. They cover 75% of surface drip and automated surge valves and 50% of all other water optimization projects (AWOP info). $62,684,494 more was requested then awarded, so demand is high. With SB 277, $200 million more was given to this program, $170 million of which comes from our state and $30 million of which comes from the federal American Rescue Plan (SB 277). While this is a significant amount of money, it is only a one-time investment. Funding will need to continue for decades. Raising outdoor water tax on municipalities should be considered to fund programs such as these.

Other Considerations

While we should continue to try and improve water conservation in agriculture throughout the state, we must ask ourselves a somewhat uncomfortable question: do we need these farms?

Let me present two other options:

System Conservation Pilot Program

At the end of 2024, the Salt Lake Tribune published an article with a shocking headline: Utah Will Pay Millions for Farmers to Leave Fields Empty – and Leave Water For the Colorado River. This is through the System Conservation Pilot Program. Funded by the Inflation Reduction Act of 2022, it pays farmers not to farm - a radical idea. In 2023, there were 20 projects in Utah, costing a total of $15,969,053. 15,090 acre feet were saved. This is about $360 per acre foot of water.
