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

About Wellton-Mohawk Main Canal near Yuma

Wellton-Mohawk Main Canal - a vital irrigation artery in the arid southwest.

The Wellton-Mohawk Main Canal, located near Yuma, Arizona, serves as an essential lifeline for agriculture in the arid landscape of the Lower Gila watershed. This canal channels water efficiently through its course, demonstrating its importance in managing the region's limited water resources.

The watershed context

The Wellton-Mohawk Main Canal functions within the broader Lower Gila watershed, which is characterized by its dynamic hydrology. The region experiences considerable fluctuations in water flow due to summer monsoon thunderstorms that can trigger flash flooding, contrasted by dry stretches where many channels may run almost completely dry. In addition to these thunderstorms, winter storms and the seasonal melting of high-country snow contribute to the water supply for the larger rivers that feed into the area.

Nearby, this canal is in good company, with peers such as the Bruce Church Wasteway and various turnouts related to Gila Monster Farms all working to facilitate agricultural irrigation. Without these channels, the arid environment would significantly limit agricultural possibilities, underpinning the critical nature of water management in the region.

Why the data matters here

The U.S. Geological Survey (USGS) station monitoring the Wellton-Mohawk Main Canal provides valuable data on water levels and discharge. Currently, the canal is operating within a measured range, with readings tracking over 50 years. A comparison of today's water level against the median for this calendar day gives a clearer picture of current conditions, rather than relying solely on an absolute elevation. This context helps stakeholders, from farmers to conservationists, understand fluctuations in water availability, particularly in a region where unpredictable weather patterns can drastically affect water flow and agricultural viability.

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.
