The Shrinking Great Salt Lake: What It Means for Your Water Supply

There’s something surreal about watching a lake vanish.

Not just any lake, either—the Great Salt Lake, that shimmering giant in our Utah backyard, is disappearing like a magician’s final trick. But this isn't a show. It’s a crisis. And here's the kicker: it's not just birds, brine shrimp, and boaters who are feeling it.

🏠 Your taps. Your showers. Your lawn. Your life. They're all tied to that shrinking shoreline.

Let’s break it down, fast-paced and no-fluff style—what’s happening to the lake, why it matters more than you think, and how it could change the way your plumbing and water usage work from Magna to Millcreek, from Kearns to Cottonwood Heights.

🌊 Where Did All the Water Go?

Picture this: In the 1980s, the Great Salt Lake covered about 3,300 square miles—a sparkling inland sea. Fast forward to now, and we’re hitting record lows. The lake has lost more than 70% of its volume and nearly two-thirds of its surface area. That’s not a typo. That’s a disaster.

Why?

Because we're draining it faster than snowmelt can fill it. Water that would normally feed the lake is being siphoned off upstream for agriculture, development, and urban water needs. Cities like West Valley, Layton, Sandy, and even Park City pull from the same sources—rivers like the Bear, Weber, and Jordan—before they ever reach the lakebed.

Throw in prolonged droughts, rising temperatures, and rapid growth along the Wasatch Front, and what do you get?

A thirsty lake...and a thirsty population.

🚿 What Does This Mean for Your Water Supply?

This isn’t just a scenic loss—it’s a plumbing problem in the making. Here’s what’s lurking just below the surface:

1. Increased Demand, Decreased Supply

As lake levels shrink, it’s not just the lake suffering. The snowpack that feeds it is also under stress. Less runoff means less water in reservoirs. That’s the same water you're using to fill your bathtub in Taylorsville, water your roses in Holladay, or run your dishwasher in West Jordan.

And with more people moving in every year, the demand keeps climbing while the supply shrinks.

That means water restrictions. Tiered billing. Even rate hikes.

2. Water Quality Could Take a Hit

As water sources dry up or get diverted, water managers might be forced to rely more heavily on lower-quality sources or dig deeper into aquifers. That often means harder water—more minerals, more buildup in your pipes, more stress on your water heater, and yes, more frequent plumbing calls.

If you’re in Magna, Kearns, or Glendale, you're probably already dealing with hard water scale that crunches under your fingers. Imagine it worse. Grittier. Stickier. Not fun.

3. Dust...in Your Water?!

Here’s where it gets real: the exposed lakebed isn’t just dry—it’s toxic.

We’re talking arsenic, mercury, and other nasty stuff buried under centuries of lake sediment. When winds kick up over that dry basin, guess what flies into the air? That dust doesn’t just vanish. It settles—on your car, in your lungs, and in your water catchment systems.

Now imagine that dust making its way into your gutters, your filters, your swamp cooler system. It’s not outlandish. It’s already happening.

🧠 What the Experts Are Saying (and Why It Should Scare You)

Water engineers, climate scientists, and yes—even plumbers—are raising alarms. Utah’s Division of Water Resources has issued multiple drought contingency plans. Salt Lake City has already tested voluntary restrictions and tiered billing.

Here’s a quick-fire reality check:

• The Jordan River is flowing lower than usual.

• Deeper wells are being drilled statewide.

• Water reuse projects are being fast-tracked.

When the systems that bring water into your home start changing at the source, you can bet that changes will show up inside your home, too.

🛁 What You Might Notice at Home (Sooner Than You Think)

Here’s what might happen if you live anywhere from Sugar House to West Valley:

• Your water pressure might dip unexpectedly during high-usage months.

• Appliances might wear out faster due to increased mineral buildup.

• That spotless shower glass you worked so hard to keep clean? Say hello to calcium crust.

• You might start seeing brown or cloudy water after heavy windstorms. That could be dust making its way into the municipal supply before full filtration.

We're not talking worst-case doomsday here. This is real-world stuff happening in homes already.

🌱 The Ripple Effects: Landscaping, Regulations, and Remodeling

Think it's just about drinking water? Think again.

Your lawn is part of the equation. Many cities, including Sandy and South Salt Lake, are encouraging or mandating xeriscaping—a fancy word for swapping thirsty lawns for rock, mulch, or native plants. Some West Side areas, like Granger-Hunter Improvement District, are even offering cash incentives to rip out grass.

Planning a bathroom remodel in Holladay? Be prepared for stricter fixture requirements. Plumbing codes are slowly shifting toward ultra-low-flow fixtures, and some municipalities are pushing for graywater systems to recycle sink or shower water for irrigation.

🧰 What You Can Do (Right Now) to Get Ahead of It

You can’t refill the lake on your own. But you can make moves to protect your home, your plumbing, and your budget.

✅ Get a Water Softener (If You Don’t Have One)

Hard water is only getting harder. If you’re seeing crusty faucets or flaky skin, it might be time. Bonus: your appliances will thank you.

✅ Swap Out Old Fixtures

That leaky toilet that runs all night? It’s wasting gallons a day. Low-flow toilets and aerated faucets use a fraction of the water with no performance loss.

✅ Rethink Your Lawn

Seriously. That carpet of grass is guzzling up to 3,000 gallons a month in summer. Cut back, go native, or get creative with xeriscaping. You’ll save water—and cash.

✅ Install a Sediment Filter

If you’re near a dusty zone (looking at you, Tooele County and parts of Daybreak), you don’t want lakebed dust clogging your systems. A simple whole-house sediment filter can help.

✅ Stay Informed

Follow your local water district’s updates. From Taylorsville-Bennion to Salt Lake City Public Utilities, each has different rules, updates, and rebate programs.

🔮 The Bottom Line: The Lake Is Talking. Are We Listening?

The shrinking Great Salt Lake isn’t just a Utah headline—it’s a home issue. A faucet issue. A garden hose issue. It’s a warning wrapped in brine, blowing across the valley in gusts of dust.

It’s the kind of thing that can sneak up on you: one dry winter, one clogged pipe, one murky faucet flow at a time.

But knowledge is power. And when you understand how this lake’s collapse connects to your kitchen sink, you can make smart changes now—before the problem shows up uninvited in your next water bill or plumber’s visit.

Because while the Great Salt Lake might be shrinking, your impact doesn’t have to.
