Nibi Metrics
Real-time water levels, forecasts, and alerts for lakes and rivers across Canada and the US. Built on official government data.
Nibi Metrics turns raw gauge readings from official hydrometric networks into something a person standing on a dock can actually use: is the water high or low for today, which way is it moving, and how unusual is this? This page explains where every number on the platform comes from and what we do to it along the way.

About Santa Cruz River at Silverlake Road, at Tucson
Santa Cruz River - A vital waterway of the desert.
The Santa Cruz River at Silverlake Road in Tucson, Arizona, is an important natural feature within the Upper Santa Cruz watershed. This section of the river captures the dynamic interactions of its environment, where water scarcity and seasonal surges create unique ecological conditions.
Why the data matters here
Today's reading from the Santa Cruz River, collected by the U.S. Geological Survey, provides critical insight into the river's flow dynamics. The monitoring station measures both the river's elevation and discharge, helping to contextualize how much water is present relative to historical norms. Given the region's arid Southwest hydrology, where flash floods from summer monsoon thunderstorms and winter storms can lead to dramatic variations in river conditions, understanding current readings is essential. The data reflects not only day-to-day changes but also broader trends within this unique ecosystem.
With the river's history of fluctuating flows—measured across the past four years by USGS—today's elevation can be compared against the median for this date across the historical record. This comparison is more meaningful than raw numbers alone, providing a clearer picture of how the water levels respond to seasonal patterns and weather events. Whether you're a local resident, a farmer relying on water from the river, or just an interested observer, this data is key to understanding the Santa Cruz River’s role in the community and environment.
How this page is built
Readings come from official government gauges and are rolled into daily records: the daily mean, high and low for every day on record. Each calendar day gets its own baseline from the full history, so the level you see is compared against what this specific date usually looks like rather than an annual average.
