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 Gila River below Painted Rock Dam

Gila River below Painted Rock Dam - a crucial artery in the arid Southwest.

The Gila River, flowing below the Painted Rock Dam in Arizona, is a vital lifeline for both ecosystems and communities in the Lower Gila watershed. This reach of the river measures the response to seasonal fluctuations in the region’s unique hydrological patterns. The river traverses an expansive drainage area of roughly 50,910 square miles, capturing the dynamic interactions of stormwater and snowmelt in this largely arid landscape.

The watershed context

The Lower Gila watershed is shaped by the complex interplay between summer monsoon thunderstorms and winter snowmelt. This region experiences intense storm events that can lead to violent flash floods, interspersed with periods where many channels may run dry. The Gila River itself is a robust waterway during peak flow events, but understanding its variations in a water-scarce environment is essential for effective management and conservation efforts. Nearby water sources, such as the Bruce Church Wasteway and the Gila Monster Farms Turnouts, contribute to the intricate network of water management in the area, reflecting both agricultural demands and ecological needs.

Why the data matters here

Today's reading from the Gila River below Painted Rock Dam provides a snapshot of the current hydrological state, compared against the median for this calendar day across the station's historical record — spanning over 50 years. This data is crucial, as it allows researchers, farmers, and flood-watchers to understand how today’s level stands in relation to typical conditions for this time of year. Monitoring by the U.S. Geological Survey ensures the data is reliable, offering insights that can inform water management decisions and help predict the river's behavior in the face of changing weather patterns.

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.
