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.

About Birch C near Circle AK

Birch Creek - A vital link in the subarctic hydrology.

Birch Creek near Circle, Alaska, is a noteworthy watercourse that contributes significantly to its surrounding environment. Draining an area of approximately 2,150 square miles, this river collects water from its extensive watershed, which plays a crucial role in the intricate hydrology typical of subarctic regions.

Why the data matters here

The Birch Creek station, operated by the U.S. Geological Survey (USGS), provides essential discharge measurements. This data is vital for understanding changes in water levels and the overall health of the ecosystem. The seasonal ebb and flow of Birch Creek are guided by the annual cycle of spring snowmelt and potential ice jams during breakup.

Today's reading offers a snapshot of Birch Creek's current flow conditions, allowing for comparison against the median for this calendar day from the station’s records over the past six years. Understanding these figures is critical for managing water use in various sectors and for flood awareness—key information for local residents and stakeholders relying on the river’s resources.

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.
