So far this year there have been 102 days in which a precipitation event has been recorded in Salt Lake County. Each time it rains, precipitation gauges around the valley activate and begin measuring and reporting rainfall back to the base station at the county government center. This data is decoded and displayed on the Watershed Planning & Restoration team’s  monitoring and gauging program website

The Watershed Program is responsible for maintaining 32 stream and rainfall gauges throughout the county. Their new website replaces an outdated version that helps the team monitor gauging sites and provides a platform for the public to access gauge data.

“There’s no better way to display this data than spatially,” said Bob Thompson, Watershed Program Manager. “With respect to the data, this website provides a more user friendly graphical interface than our previous page.”

In addition to flow and precipitation totals, data is also available on parameters relating to the status of each gauge and when it last reported. This information helps field crews identify peak flows, heavy precipitation events, and malfunctioning equipment.

Users can view data in a few different layouts. The  map view shows the location of each gauge and displays real-time data when a site is selected. The  dashboard shows real-time data for all active gauges. Users can also download gauge data in spreadsheet format.
