Great Salt Lake Hydro Mapper

Current Conditions

This page displays discharge data for USGS streamgages located on major surface water inflows to GSL. Lake surface elevations for gages on the north (Saline) and south (Saltair and south side of the railroad causeway) arms of the lake are shown at the bottom of this page. Because most surface water inflows enter the south arm of the lake, its surface elevation is usually higher than the north arm. Currently, water can move through the causeway via an engineered breach and to a lesser extent through the rock-fill causeway material. Gage locations are shown on the map.

Data are from the USGS National Water Information System.

Current Daily: Mean daily value. Values are typically from the day before.

Median, Minimum, Maximum: Calculated from daily values for the period of record at each station.

Real-Time Data

Wind events can cause flow reversals where water flows from GSL into Farmington Bay. Flows from GSL to Farmington Bay are indicated by negative discharge values.

Lake Stage

Great Salt Lake at Saltair Boat Harbor, UT

Monitors lake elevation in the south arm and is located in the GSL Marina harbor, at the southern end of GSL. Water surface elevation measured by this gage is representative of the portion of GSL south of the railroad causeway. Historic water surface elevation measurements made at various locations on the southern end of GSL have been combined such that this gage is associated with an elevation record dating back to 1847. Some data included on this graph are provisional and may be revised.

USGS Gaging Station 10010000

Great Salt Lake Near Saline, UT

Monitors lake elevation in the north arm and is located about 3.4 miles northwest of Saline, UT, in the historic Little Valley boat harbor. Water surface elevation measured by this gage is representative of the portion of GSL north of the railroad causeway. This gage has an elevation record dating back to 1966. Some data included on this graph are provisional and may be revised.
