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 San Pedro River near Tombstone
San Pedro River - a dynamic flow in an arid landscape.
The San Pedro River winds its way near Tombstone, Arizona, providing a crucial lifeline in an otherwise dry region. This river plays an essential role in supporting both the local ecosystem and human activities in the surrounding area. With a drainage area of approximately 1,740 square miles upstream of the monitoring station, the San Pedro River channels water that can be especially vital during the seasonal fluctuations characteristic of the arid Southwest.
The watershed context
Part of the Upper San Pedro watershed, the San Pedro River benefits from the seasonal patterns of Arizona’s hydrology. In summertime, violent flash floods driven by monsoon thunderstorms can transform the river, sometimes resulting in rapid increases in water levels. Winter storms and high-country snowmelt feed the river, contributing to its flow, though many channels can run dry between these significant hydrological events. Nearby waterways such as Babocomari River and Banning Creek also contribute to the local hydrology, creating a network of water sources that sustain diverse vegetation and wildlife, even amid challenging climatic conditions.
Why the data matters here
Monitoring water levels on the San Pedro River near Tombstone is crucial for understanding the river's dynamic flow. Today’s reading, provided by the U.S. Geological Survey (USGS), offers vital insights into current conditions. Each measurement is compared against the median for this calendar day across the station's historical record, which spans more than 50 years. This comparison is important because it allows residents and stakeholders to assess how the current water level stands in relation to typical conditions throughout the years. By focusing on this contextual understanding, we can better appreciate the implications of water flow variations in a region known for its extreme climate and unique ecological needs.
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.
