Real-time water monitoring data released Friday by the U.S. Geological Survey shows the Weber River near Plain City is flowing at a gage height of 10.51 feet, while the Great Salt Lake at Saltair Boat Harbor maintains a water surface elevation of 4190.8 feet.
Weber River Gage Levels
According to data from the USGS monitoring station near Plain City, the Weber River's gage height was recorded at 10.51 feet as of 12:45 AM MDT on July 24, 2026. This measurement is currently classified as provisional.
The river's current level remains well below several critical flood thresholds established for the area. The USGS monitoring station identifies an action stage at 25 feet, with subsequent stages of minor flood at 27 feet, moderate flood at 28 feet, and major flood at 29 feet.
River Monitoring Metrics
The monitoring site for the Weber River near Plain City provides extensive historical context for the waterway. The USGS maintains continuous data for gage height at this location dating back to October 1, 2007.
In addition to gage height, the station tracks several other environmental metrics. Continuous data collection includes discharge measured in cubic feet per second, which has been recorded since October 1, 1986. The site also monitors water temperature in degrees Celsius and specific conductance of unfiltered water in microsiemens per centimeter, with temperature data available from September 28, 2018, through July 23, 2026.
Great Salt Lake Elevation
At the Saltair Boat Harbor monitoring location, the Great Salt Lake's water surface elevation was recorded at 4190.8 feet above NGVD 1929 as of 1:45 AM MDT on July 24, 2026. This data is also noted as provisional.
This current elevation sits below the historical median for this time of year. Based on 36 years of daily mean data, the lake's median elevation is recorded at 4196.395 feet. The monitoring station also tracks a range of historical extremes, including a low of 4189.8 feet and a high of 4203.5 feet.
Historical Lake Statistics
The USGS provides detailed statistical ranges for the Great Salt Lake to help researchers understand current water levels relative to historical norms. For the current period, the 25th percentile elevation is 4193.945 feet, while the 75th percentile reaches 4200.05 feet. The mean elevation is calculated at 4196.887 feet.
The Saltair Boat Harbor station, located in Salt Lake County, operates as part of a larger hydrologic network. It tracks data within the Great Salt Lake subbasin (hydrologic unit 16020310) and covers a massive drainage basin of 22,060 square miles.
Agency Cooperation
Both monitoring stations are part of a cooperative effort involving several state and federal agencies. The Weber River station operates in cooperation with the Utah Division of Forestry, Fire and State Lands, the Utah Division of Water Rights, the U.S. Bureau of Reclamation Upper Colorado Region, and USGS Cooperative Matching Funds.
Similarly, the Great Salt Lake monitoring at Saltair Boat Harbor is conducted in cooperation with the Utah Division of Forestry, Fire and State Lands and the USGS Cooperative Matching Funds.
Long-term Data Records
The USGS continues to provide continuous data for these locations using automated sensors. For the Weber River site, continuous water data collection has been active since 1986. For the Great Salt Lake, the station provides a long-term record of lake surface elevation dating back to 1847.
