Imperial Irrigation District has completed construction of the first phase of its air quality project at the Salton Sea’s Red Hill Bay.
Using something so simple as a tractor pulling a bull plow across a dry lake bed, the district has built long narrow furrows, to reduce wind velocity on the ground, and thereby control the amount of dust being blown around on windy days. to implement dust control measures.
Oddly enough the furrows of dirt, actually trap soil and dust particles.
The next phase of the project involves planting vegetation or installing irrigation infrastructure between the furrows to further reduce blowing dust.
The furrows that have been built, could reduce dust emissions by up to 90%.
Future project phases will address the site’s water supply, irrigation and seeding.
