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 Rincon Creek near Tucson, AZ.
Rincon Creek - A dynamic waterway shaped by Arizona's climate.
Rincon Creek flows gracefully through the landscape near Tucson, Arizona, in the Rillito watershed. This region experiences a complex hydrological pattern that influences the creek's behavior and health. Summer monsoon thunderstorms can transform the creek dramatically, bringing the potential for sudden and violent flash floods. These intense storm events are juxtaposed with winter storms and the gradual melting of high-country snow, which feed the larger river systems but may leave many channels dry between these events.
The watershed context
Rincon Creek is part of the Rillito watershed, which includes various neighboring waterways such as Barrel Canyon and Brawley Wash. The creek's drainage area extends roughly 44.8 square miles, providing a crucial contribution to the local hydrology. As it flows, Rincon Creek interacts with various smaller tributaries such as Cienega Creek and Sabino Creek, all of which share the same arid conditions that characterize southeastern Arizona. The relationship between these waterways is essential for the communities and ecosystems that depend on them.
Why the data matters here
The measurement at Rincon Creek is crucial for understanding the local hydrological dynamics. The United States Geological Survey (USGS) monitors this creek, providing valuable data on discharge levels that can inform residents and land users about current conditions. Today’s reading, when compared against the median for this calendar day across the station's historical record of 39 years, offers a vital perspective on how current conditions measure up against the past. This comparison, rather than the raw elevation, provides insight into the creek’s flow patterns and helps assess risks of flash flooding or low water conditions due to the seasonal fluctuations typical of this arid landscape.
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.
