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 North Gila Main Canal near Yuma

North Gila Main Canal - A lifeline in the arid Southwest.

The North Gila Main Canal near Yuma, Arizona, serves as a crucial water conduit in the arid Southwest, reflecting the complexities of water management in this region. This canal channels water from the surrounding agricultural landscapes, meeting the irrigation needs of local farms and sustaining the communities reliant on its flow.

The watershed context

This section of the canal is part of the larger Lower Colorado watershed, which stretches across a semi-arid landscape where water is both a precious resource and a potential hazard due to seasonal summer monsoon storms. In this region, summer thunderstorms can lead to sudden flash floods, while winter storms and snowmelt from higher elevations contribute to the flow of larger rivers. Given these dynamics, the North Gila Main Canal plays a pivotal role in managing water resources in an area where many channels may run dry between these significant weather events.

Why the data matters here

Understanding the data from the North Gila Main Canal is vital for effective water use and management in the region. The United States Geological Survey (USGS) operates this monitoring station, providing real-time data that helps inform decisions related to agriculture, flood management, and water conservation. Today’s reading, while not specified in the metadata, is compared against the median for this calendar day over the past 50 years of recorded data. Such comparisons offer a clearer picture than a raw gauge elevation alone, allowing stakeholders to make informed decisions about water use and to anticipate possible changes in flow due to seasonal 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.
