Reliable, high quality stream data is critical to understanding the overall health of a watershed. In particular, how development and other landscape-altering activities can negatively impact stream health and natural stream functions.
Routine monitoring of Salt Lake County streams allows the Watershed Program to assess where watershed conditions appear to be changing, identify areas of concern, and guide stream restoration efforts.
An expanded water quality data collection program was undertaken in 2009, and has been refined over time to reflect specific interests in the watershed.
Data collected include:

agencies at the federal, state, and local levels.

Salt Lake County Watershed published the first annual 2016 Water Quality Report. This report provides a fine scale analysis
of the health of County waterways. Site-specific data tracks the functionality of sub-basins and, over time, track how these ecosystems respond to management practices and restoration efforts.
The Watershed Program maintains a network of streamflow and precipitation gauges located throughout county. Daily flow data collected from many stream sites is needed to forecast floods, manage water quality, and assess water availability. In addition,
stream gauge data is key to understanding the relationship between precipitation and how quickly streamflows peak.
