How Pool Chemistry Changes During a Drought in Northern California

Dylan hadn’t had to top off his pool in nearly a month, which was odd for late June in Rocklin. No big splash-outs, no obvious leaks, just stubbornly low water that kept creeping downward. Then came the notices—local water restrictions were going into effect. He figured he’d just ride it out, but within a couple weeks, his pool turned a little hazy, then fully cloudy. "I haven’t changed anything," he said. "Why does it look like a swamp now?"

It’s not just about water levels—drought affects your pool chemistry in ways most Northern California homeowners don’t expect.

How Drought Affects Pool Chemistry in Northern California

When rainfall is low, heat is high, and evaporation kicks into overdrive, your pool doesn’t just lose water—it loses balance.

Increased Evaporation = Rising Chemical Concentrations

As water evaporates, chemicals like calcium, cyanuric acid, and total dissolved solids (TDS) become more concentrated. You’re left with a stronger chemical brew that can irritate skin and eyes, corrode equipment, or damage pool surfaces.

Higher Temperatures = Faster Chlorine Burn-off

The hotter it gets, the faster chlorine gets eaten up by the sun—especially if your stabilizer levels are off. That means algae can creep in even if your pump’s working hard.

Less Dilution = More Contamination

Normally, rainfall helps flush out tiny particles and contaminants. Without that regular top-off, sunscreen, sweat, and debris linger longer—leading to cloudy water, foamy buildup, and unpleasant smells.

What You Can Do to Protect Your Pool During a Drought

Living in Lincoln, Loomis, or anywhere else in NorCal, you’ll likely face water restrictions during dry seasons. But your pool doesn’t have to suffer.

Adjust Chemical Levels Thoughtfully

If you’re topping off less often, test your water more often—at least twice a week. Keep an eye on:

  • Calcium hardness

  • Total dissolved solids

  • Cyanuric acid

  • Chlorine and pH

Add a Pool Cover (or Use It More Often)

A high-quality pool cover can reduce evaporation by up to 90%. That saves water and keeps chemicals more stable.

Use Algaecide Proactively

Don’t wait until green patches show up. Use a preventative algaecide weekly to help reduce chlorine demand.

Skim and Brush on a Regular Basis

With less dilution, organic debris builds up faster. Skim daily if possible and brush the walls weekly to keep surfaces clean and water flow steady.

Watch for Staining or Scale

White crusty spots or brown stains? That’s a sign of mineral imbalance. You may need to use a sequestering agent to keep minerals from binding to surfaces.
