California Wetland Project Addressed Dust Linked to Wheezing
Residents near the Salton Sea may see fewer respiratory issues as authorities work to suppress dust from the exposed lakebed.

In May 2025, California completed the 750-acre East Pond Expansion at the Salton Sea to manage dust emissions from the lakebed. This restoration effort aims to improve respiratory health for nearby communities long affected by airborne particulate matter.
Why it matters
Dust storms from the receding Salton Sea have historically increased the prevalence of wheezing and bronchitic symptoms among local children. By covering exposed sediments with water, this project seeks to reduce the volume of fine particles blowing into residential areas.
A study of 722 children linked every 100 hours of dust-storm exposure (PM10 concentrations over 150 micrograms per cubic meter) to a 9.5-percentage-point rise in wheezing and a 4.6-point increase in bronchitic symptoms for those living within 11 kilometres of the Salton Sea.
The players
California Department of Water Resources
The state agency responsible for managing the state's water supply and overseeing large-scale environmental restoration projects.
The details
The project uses a system of shallow ponds, berms, and nesting islands to maintain permanent water cover over previously dry sediments. By preventing these sediments from drying out and becoming airborne, the system limits the release of PM10 particles. The combined 2,000-acre area functions as a barrier against dust emissions while simultaneously restoring critical habitat for migratory birds along the Pacific Flyway.
Timeline
Early April 2025: Filling of the initial East Pond began.
May 22, 2025: California officials announced the completion of the East Pond Expansion.
Health Landscape
This expansion represents a critical milestone in the Species Conservation Habitat Project, which aims to mitigate environmental degradation. It marks a broader shift toward using land-management interventions to address the environmental drivers of pediatric respiratory conditions.
Residents living within 11 kilometres of the Salton Sea should remain aware that high-dust days can exacerbate respiratory symptoms like wheezing. If you or your child experience persistent breathing changes during dusty conditions, discuss monitoring strategies with your primary care physician.
The takeaway
Restoring lakebeds can reduce the hazardous dust that triggers pediatric respiratory issues in the Imperial Valley. Monitor local air quality alerts and consult your doctor if your child experiences increased wheezing during high-wind events.
