The southern portion of the Great Salt Lake has reached a new historic low, according to U.S. Geological Survey information collected at the SaltAir gauge location. Average daily water levels have dropped about an inch below the previous record established in 1963.
Utah Department of Natural Resources executive director Brian Steed stated that while the lake has been gradually declining for some time, current drought conditions have accelerated the fall to this new low level.
Ryan Rowland, the USGS Utah Water Science Center data chief, said that based on current trends and historical data, the USGS anticipates water levels may decline an additional foot over the next several months. Rowland noted that this information is critical for helping resource managers make informed decisions.
Extreme drought conditions are also impacting streamflow levels across the state. Currently, 63% of streamgages with at least 20 years of record are reporting below-normal flows.
The USGS emphasizes that average daily values provide the most representative measurement because wind events can cause temporary changes in lake levels. The agency maintains a record of Great Salt Lake elevations dating back to 1847.
Brian Steed stated that finding ways to balance Utah's growth with maintaining a healthy lake requires working together among elected leaders, agencies, industry, stakeholders, and citizens.
