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 Virgin River at Littlefield
Virgin River at Littlefield - a vital corridor through the arid landscape.
The Virgin River at Littlefield is a significant waterway in Arizona's arid Southwest, draining a substantial catchment area of approximately 5,090 square miles. This river plays a key role in sustaining the surrounding ecosystem, particularly during the seasonal fluctuations influenced by summer monsoons and winter storms.
The watershed context
Located within the Lower Virgin watershed, this river connects with several other water bodies, including the Mesquite Canal and various stretches of the Virgin River, notably the reach above the Narrows and near Bloomington. In the summertime, residents may notice dramatic weather events, as thunderstorms can lead to rapid increases in flow, while during other parts of the year, such natural variability may leave channels temporarily dry. This stark contrast highlights the importance of the river system to the broader landscape, providing critical water flow during crucial periods and allowing for diverse ecological interactions.
Why the data matters here
The measurement data from the U.S. Geological Survey (USGS) at this site is essential for monitoring the river's health and water availability. Understanding today's flow conditions compared to the historical median for this date helps communities, farmers, and environmental managers gauge current river performance and predict future behaviors. Today's reading can provide a better view of how this vital resource is holding up against its historical trends, influencing everything from local water usage to flood risk preparation. Keeping tabs on these levels not only aids in understanding the river's current state but also serves to inform strategies for sustainable management as needs and conditions evolve.
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.
