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.

Water Stories

The flood of record that was overtaken

For five years, spring 2019 was the mark every Lake Muskoka decision answered to. In April 2026 the lake went two centimeters higher - and the official books have not caught up yet.

Why the Assiniboine floods every spring

Inside the freshet cycle that puts Manitoba shorelines at risk each year - and why 2026 broke the script.

Flash Flood Alley: how Texas rivers rise in hours

Why Central and South Texas rivers go from gravel beds to fifty-year records in an afternoon - including July 2026 on the Nueces.

About Virgin River Blw Conf of Muddy River near Overton

Virgin River Below Confluence of Muddy River - A vital waterway in the arid Nevada landscape.

The Virgin River below the confluence of the Muddy River near Overton, Nevada, plays an important role in the local hydrology, particularly in a region characterized by its arid Great Basin climate. This section of the Virgin River is part of a larger watershed that ultimately feeds into Lake Mead, a crucial reservoir for the southwestern United States.

Why the data matters here

At this river station, hydrological data is vital for understanding fluctuations in water levels and streamflow. The river has a drainage area of roughly 13,393 square miles above the station, indicating a substantial catchment that contributes to its flow dynamics. The data provided by the U.S. Geological Survey (USGS) helps local communities monitor the river's behavior, particularly important during events like summer thunderstorms that can lead to flash floods.

Today's reading from this gauge is significant when compared to the median for this calendar day, offering insights into the river’s typical patterns over the years. With a historical record spanning more than seven years, tracking these levels becomes essential for water resource management, environmental monitoring, and community preparedness in this unique desert hydrology. Understanding this data goes beyond mere elevation; it reflects the river’s health and responsiveness to seasonal and climatic variations impacting the Great Basin region.

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.
