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 Little Colorado R above Lyman Lake near ST. Johns
Little Colorado River - a vital lifeline in an arid landscape.
The Little Colorado River, located above Lyman Lake near St. Johns, Arizona, serves as a crucial source of water within the arid Southwest region. This river not only plays an essential role in the local hydrology but also impacts the ecosystem and communities reliant on its water.
The watershed context
This stretch of the Little Colorado River traverses a watershed area of approximately 706 square miles, draining water that supports both the flora and fauna in the region. The primary hydrological influences are the seasonal summer monsoon thunderstorms, which can unleash sudden and violent flash floods, and the winter storms that bring high-country snowmelt. It is important to note that many channels in this region may run dry between such events, highlighting the dynamic and sometimes unpredictable nature of water flow in arid landscapes.
The river has notable peers, including the larger Little Colorado River at Greer and Lyman Lake. These connections form a network of waterways that are deeply intertwined with the health of the watershed, ultimately supporting local agriculture and recreation.
Why the data matters here
Monitoring data from the United States Geological Survey (USGS) is critical for understanding the flow conditions of the Little Colorado River. Insights derived from the river's gauge readings allow for better management of water resources, especially during periods of variable flow caused by monsoons or snowmelt. Today’s measurement provides a snapshot of the river’s current state, which is compared against the median for this date across the past 50 years of records.
This context is vital; relying on just raw elevation can obscure important changes in water levels that could impact irrigation practices, flood preparedness, and ecological health. Understanding the trends in comparison to the historical median enables community stakeholders to make informed decisions about water usage and conservation, adapting to the nuances of this challenging 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.
