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.

How snowpack becomes summer water

The science of snow water equivalent and why it drives the season ahead.

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 National C near McCarthy AK

National C - a river flowing through the heart of Alaska's wilderness.

The National C near McCarthy, Alaska, is a striking river that reflects the raw natural beauty of its surroundings. Nestled within the Chitina River watershed, this river is fed by the seasonal rhythms of Alaskan hydrology, where the spring breakup and the snowmelt generate significant water flow. During the summer months, rivers in this region may rise further due to glacier melt, although specifics about the glacial contributions to this particular waterbody are not provided.

Why the data matters here

Today's reading at the National C showcases the river's status relative to historical data provided by the U.S. Geological Survey (USGS). When looking at the current water levels, it is essential to understand the context—that today’s reading compared with the median for this calendar day across five years of historical records gives a better perspective than raw elevation alone. As conditions fluctuate with the seasons, insights gleaned from historical comparisons help inform anglers, flood-watchers, and those engaged in the natural resource management of this remarkable part of Alaska.

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.
