Less dust raised
When a lake retreats, the exposed bottom can become a source of dust. Containing them requires interventions and maintenance that have costs and consumption.
Research and local documents ↓What the evidence tells us
At Owens Lake, the operator reports a 99.4% reduction in its dust emission control metric. The measures include water management, gravel and vegetation in the treated areas.

The diagram compares choices and conditions for putting them into practice. Measured outcomes and their limits are discussed in the evidence.
Research and local documents ↓Conditions and limits
It's an indicator of the manager's schedule, not the disappearance of all human exposure. Dust control is not equivalent to restoring the original lake.
Other possible benefits
Protection of air quality around the basin, with attention to the use of water.
