Study Finds Water Conservation Key to Restoring Great Salt Lake
Researchers propose reducing agricultural irrigation by 35% to address the lake's decades-long water loss and ecological threats.
- The Great Salt Lake has lost over 15 billion cubic yards of water in 30 years, shrinking at a rate of 4 inches annually, largely due to human water use and climate change.
- Agriculture accounts for nearly three-quarters of water diverted from the lake's watershed, with 80% of agricultural water used to irrigate alfalfa and hay for livestock feed.
- Proposed measures include reducing irrigation of water-intensive crops, fallowing hay fields, and offering financial compensation to farmers and ranchers for lost income.
- The lake's decline threatens biodiversity, including habitats for 10 million migratory birds, and poses health risks from toxic dust released from the exposed lakebed.
- Researchers estimate conservation efforts would cost Utah residents between $29 and $124 annually, with potential to restore the lake to an ecologically healthy level within a decade.
