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 above the Narrows near Littlefield
Virgin River above the Narrows - a dynamic waterway shaped by seasonal storms.
The Virgin River above the Narrows flows through the arid landscapes of Arizona, showcasing the dramatic hydrology characteristic of the Southwest. This section of the Virgin River is part of the Lower Virgin watershed and spans a significant drainage area of approximately 4,415 square miles upstream. The river is known for its fluctuations, influenced heavily by the region's summer monsoon thunderstorms and winter storms that trigger snowmelt from high-country areas.
The watershed context
The Lower Virgin watershed is home to several tributaries and branching waterways, and the Virgin River above the Narrows is a key artery in this system. Its peers, including Mesquite Canal near Mesquite and other segments of the Virgin River, contribute to the hydrological complexity of the region. The intense summer thunderstorms often lead to sudden, violent flash floods, while the winter months can see the river swell from melting snow, creating a dynamic environment marked by rapid changes in flow and water levels.
Why the data matters here
As of today, the USGS reports a flow measurement for the Virgin River above the Narrows. Comparing this current reading against the median for this calendar day allows stakeholders, from anglers to flood-watchers, to assess how the river's current state measures up to historical norms. The historical data gathered over more than 28 years helps in understanding the river's behavior, informing decisions in water management and land use along its banks. Today’s reading is a vital benchmark for gauging the effects of rainfall and runoff on this energetic river.
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.
