For 90 years the Owens Lake in central California was drained almost dry to supply water for Los Angeles. Fine alkaline dust from the exposed lakebed, however, greatly increased air pollution. This program profiles the Owens Lake Remediation Project, as the Great Basin Unified Air Pollution Control District and the Los Angeles Department of Water and Power use managed vegitation and shallow flooding to restore the lake and improve air quality when the dust settles.
