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 Aravaipa Creek near Mammoth, AZ.
Aravaipa Creek - A dynamic desert river
Aravaipa Creek near Mammoth, Arizona, flows through a unique landscape shaped by the region's arid climate and seasonal rainfall. This river is a vital part of the Lower San Pedro watershed, which is known for its dramatic fluctuations in flow driven by summer monsoon thunderstorms and winter snowmelt from higher elevations.
The watershed context
Aravaipa Creek is nourished by a catchment covering approximately 537 square miles. During summer, intense thunderstorms can lead to rapid increases in water levels, often resulting in flash floods that can dramatically alter the creek's flow. In contrast, during periods without rainfall, parts of the creek may run dry, a testament to the variable nature of desert hydrology. This makes each visit to the creek a unique experience, offering diverse scenes depending on the season and recent weather patterns. Nearby, the San Pedro River at Redington Bridge influences the ecology and hydrology of the area, reinforcing the interconnected nature of these desert waterways.
Why the data matters here
Current monitoring by the U.S. Geological Survey (USGS) is crucial for understanding the changing dynamics of Aravaipa Creek. Today's reading provides insights into how the creek's flow compares to the median for this calendar day over the last 50 years. This historical context allows for better comprehension of current conditions and potential trends in water availability, which is important for local ecology, land use, and community safety during flood events.
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.
