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.

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 Chevelon Fork below Wildcat Canyon, near Winslow

Chevelon Fork below Wildcat Canyon - a dynamic river shaped by the Southwest's extremes.

Chevelon Fork meanders below Wildcat Canyon, near Winslow in Arizona, embodying the unpredictable nature of the region's hydrology. This river is part of the Chevelon Canyon watershed, a system influenced significantly by the area's arid climate and seasonal variations.

The watershed context

The Chevelon Canyon watershed drains an area of approximately 271 square miles upstream of the monitoring station. This geographical expanse captures both summer monsoon thunderstorms, which can lead to sudden and intense flash floods, and the gentle winter storms, whose snowmelt contributes to the larger rivers in the region. The hydrology here is marked by its sporadic behavior; many channels experience dry periods between these significant events, revealing the stark contrast in flow conditions across different seasons.

Why the data matters here

Today's observations from the US Geological Survey for the Chevelon Fork provide vital insights into the river's current state. The real-time gauge reading allows local farmers, anglers, and flood-watchers to navigate the often precarious conditions of the Southwest. Comparing today’s measurement against the median for this calendar day across 31 years of data helps paint a clearer picture of the river's behavior, thus offering a more meaningful assessment than a raw elevation figure alone. Understanding these dynamics is crucial for maintaining safety and managing resources in this unique and challenging hydrological environment.

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.
