Keep Tahoe Blue: How Local Cleanups Are Redefining Lake Stewardship
By Charlie Pankey | Sierra Rec Magazine
This July, while most of us were enjoying sunshine, fireworks, and lakefront barbecues, a dedicated group of over 650 volunteers quietly changed the narrative for Lake Tahoe’s Fourth of July weekend.
They picked up 1,375 pounds of trash from Tahoe’s beaches — and for the first time in years, we could actually call that progress.
In this week’s Sierra Rec Now podcast, I had the pleasure of sitting down with Marilee Movius from the League to Save Lake Tahoe (Keep Tahoe Blue) — one of the original architects behind the “Keep Tahoe Red, White & Blue” cleanup movement. We took a deep dive into what that 27% reduction in beach litter actually means — and why it’s only the tip of the iceberg when it comes to protecting this incredible place.

From 1,800 Pounds to 1,375: Why That Matters More Than You Think
Twelve years ago, Keep Tahoe Blue launched its first organized July 5th beach cleanup at just two locations. Today, that event spans the entire lake, with seven hosted cleanup hubs and 17 partner organizations. What’s more, this year’s 1,375 pounds of collected litter marked a significant 27% decrease from 2024.
“I know it sounds odd to celebrate 1,300 pounds of trash,” I told Marilee during the show, “but I couldn’t help thinking… isn’t that better than 1,800? It’s progress, right?”
Marilee’s answer was clear: “It’s a win. It means more people are picking up after themselves. It means the systems we’ve put in place are working.”
Making Cleanup Part of the Tahoe Vacation Tradition
One of the most heartwarming parts of our conversation was hearing how families are now making beach cleanup part of their holiday plans. Marilee shared the story of the Plum family, who brought their teenagers to Kings Beach after years of dreaming about a Fourth of July in Tahoe — and made the July 5th cleanup part of their trip.
It’s that kind of cultural shift — from passive observer to active steward — that’s redefining what it means to be a Tahoe lover.
Tools of the Trade: Beach Robots, Sign Experiments, and Smart Stewardship
It’s not just volunteers doing the work. Marilee talked about the BeBot beach-cleaning robot, which scrapes microplastics and debris from under the sand — the last line of defense before that waste hits the lake.
And then there’s the Conservation Communication Collaborative, a new research initiative testing the effectiveness of signage around Tahoe. Think of it as A/B testing for behavior change: Which messages inspire action? Which images stick with people long enough to make them pick up their trash?
“They’re literally roaming the beaches, asking where people are from and what kind of messages resonate,” Marilee said. “That data helps us figure out what works.”
Enter the Tahoe Blue Crew: Adopt Your Favorite Trail or Beach
If you’ve ever felt like you wanted to do more for the Sierra, meet your new favorite program: the Tahoe Blue Crew.
It’s like Adopt-a-Trail but smarter. Anyone — local, visitor, business, or hiking group — can adopt a location and commit to cleaning it up at least three times per year. The key? Participants not only clean up, they log data on what kind of trash they find.
That data has helped push real change, including:
- The first-ever municipal ban on plastic water bottles in South Lake Tahoe
- Targeted cigarette disposal stations
- More sustainable infrastructure on public beaches
With over 60 active Blue Crews and hundreds of cleanups logged since 2019, this is more than a feel-good initiative. It’s a backbone of modern conservation in the basin.

The Tahoe Blue Beach Program: Where the Right Choice Becomes the Easy One
Launched in 2024, the Tahoe Blue Beach Program is now piloting at:
- Zephyr Cove Resort
- Kings Beach State Recreation Area
- Meeks Bay
- Camp Richardson
- Tahoe Beach Club
Through a collaborative model of education, engineering, and enforcement, Keep Tahoe Blue and its partners are creating beaches that inspire stewardship — not demand it.
Think upgraded signage, improved waste disposal systems, public education campaigns, and seasonal infrastructure improvements — all designed to make it easier to do the right thing when you show up to play.
Bonus Episode Insight: What You Need to Know About Aquatic Invasive Species
Late in the episode, we also touched on a growing concern in the Tahoe region: the threat of aquatic invasive species like the golden mussel. Keep Tahoe Blue now offers training through its Eyes on the Lake program and works alongside the Tahoe Keeper program to educate boaters and paddlers on the importance of cleaning, draining, and drying all watercraft before hitting the water.
Because as Marilee reminded us: “It only takes one contaminated boat to create a battle for Tahoe’s life.”
Final Takeaway: Protect Where You Play
This episode reminded me that keeping Tahoe blue isn’t just about reacting to problems — it’s about transforming how we show up to public lands, how we model behavior for others, and how we take pride in leaving a place better than we found it.
Whether you’re a full-time local or a weekend adventurer, we each have a role to play in preserving this incredible region.
So the next time you head for Tahoe’s shoreline, bring a reusable water bottle, tuck a trash bag in your pack, and maybe — just maybe — sign up to adopt the place you love most.
We’ll see you out there.
