Salton Sea Crisis 2026: California's Shrinking Toxic Lake

🌊 CALIFORNIA WATER CRISIS SALTON SEA 2026 California's Shrinking Toxic Lake Sustainability Awakening

1 OF 10 WHAT IS IT? California's Largest Lake — And Fastest Disappearing 343 sq miles Current size — down from 376 sq miles in 1980 📍 Located in the Coachella & Imperial Valleys in Southern California — an accidental lake created by Colorado River flooding in 1905 🌊 No outlet — water only leaves by evaporation, making the lake saltier and more toxic every year Sustainability Awakening

2 OF 10 THE POISON A Lake Becoming a Toxic Dust Bowl ⚗️ Salinity: 50+ ppt Nearly twice as salty as ocean — most fish have died; mass die-offs occurred in 2023–24 ☠️ Selenium, arsenic & pesticide runoff from Imperial Valley farms have concentrated in lake sediment 🌬️ Exposed lakebed (playa): 100+ sq miles of toxic dust containing PM2.5, arsenic, and heavy metals Sustainability Awakening

3 OF 10 HEALTH CRISIS Asthma Capital of California 3x Higher asthma rates in communities near Salton Sea vs. California average 🏥 Imperial County has one of the highest pediatric asthma ER rates in California 👶 Children most vulnerable — dust storms carry toxic PM2.5 particles from exposed lakebed into homes and schools Sustainability Awakening

4 OF 10 ROOT CAUSE Colorado River Water Deal = Salton Sea Loses Its Lifeline The 2003 Quantification Settlement Agreement (QSA) diverted Imperial Valley farm drainage away from the Salton Sea to San Diego and LA 📉 Result: the sea has been losing ~1 foot of elevation per year since 2018 💧 Agricultural runoff (via the New & Alamo Rivers) was its only freshwater source — now greatly reduced 🌡️ Climate change is accelerating evaporation — projections show ~33% more surface loss by 2045 Sustainability Awakening

5 OF 10 WILDLIFE COLLAPSE From Bird Paradise to Dying Lake 🦅 400+ bird species historically used Salton Sea as the most important stop on the Pacific Flyway migratory route 🐟 Fish extinction: Corvina, tilapia & bairdiella — once thriving — largely gone due to hypersalinity 🦅 Endangered Yuma Ridgway's Rail & Snowy Plover still nest at the shrinking shorelines 📊 Waterbird count dropped 80% since 1999 as habitat collapses Sustainability Awakening

6 OF 10 COMMUNITY IMPACT Tribes & Farmworkers Bear the Burden 🪶 Torres Martinez Desert Cahuilla Indians — treaty rights tied to the Salton Sea; their ancestral territory is shrinking with the lake 👨‍🌾 60,000+ farmworkers live in Imperial Valley — majority Latino, largely uninsured, with no escape from dust exposure during field work 🏫 Schools close during dust events; children miss up to 15 days/year in affected communities This is environmental justice — the most vulnerable communities suffer most Sustainability Awakening

7 OF 10 CALIFORNIA'S PLAN $220 Million to Restore the Sea 🏗️ Salton Sea Management Program (SSMP) — CA committed $220M for wetland habitat projects & dust suppression on exposed playa 🌊 Species Conservation Habitat Project: 4,100-acre shallow water habitat being built near southern shore (2024–2026) ⚡ Lithium extraction: Imperial Valley brine contains lithium — "Lithium Valley" could fund restoration & power EV batteries 🌿 Environmental groups say $220M falls far short — full restoration needs $8–15 billion Sustainability Awakening

8 OF 10 LITHIUM VALLEY America's Hidden Battery Metal $540 billion Estimated value of lithium in the Salton Sea geothermal brines ⚡ Enough lithium to supply all of the US's EV demand — 40% of known global reserves 🏭 Berkshire Hathaway Energy, EnergySource Minerals, Controlled Thermal Resources — all building extraction pilots in 2025–26 Sustainability Awakening

9 OF 10 WHAT YOU CAN DO 5 Ways to Help the Salton Sea 1️⃣ Support the Salton Sea Authority's restoration funding campaigns 2️⃣ Write to CA legislators: demand $8B+ full restoration funding 3️⃣ Use less water — every gallon saved in the Colorado River Basin helps 4️⃣ Visit & learn: Salton Sea State Recreation Area is open to visitors 5️⃣ Support environmental justice orgs like Comite Civico del Valle Sustainability Awakening
