DELICATE WATER ZONE · D3 — Extreme drought over a member dam
Salt Lake City, Utah
The Wasatch Front drinks mountain snowmelt — creek water and the Provo River system's pools at Jordanelle and Deer Creek. Every diversion is water the Great Salt Lake never receives: the lake set its record low in 2022, and its exposed lakebed dust is the valley's air-quality problem in waiting. The lake's elevation is this zone's honest ledger.
