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 West Arrowwood Creek near Arrowwood

West Arrowwood Creek - a vital tributary of the Lower Bow basin.

Nestled in Alberta's prairie heartland, West Arrowwood Creek serves as an essential watercourse within the Lower Bow - Crowfoot watershed. With a catchment area of 781 square kilometres draining above the station, this creek reflects the dynamic nature of prairie hydrology. Known for its seasonal peaks driven by late-spring mountain snowmelt, combined with sharp rises from summer storms, the creek plays a key role in local ecosystems and agricultural water supply.

The watershed context

The Lower Bow - Crowfoot watershed is characterized by its intricate mix of river systems that support various flora and fauna. While West Arrowwood Creek itself may not have a named parent river, it contributes to the broader water narrative of the Bow River system. Nearby, the Bow River below Carseland Dam also adds to the intricate web of water flows that sustain this region. The watershed often experiences shifting water levels, especially during the spring when melting snows augment flow, and in summer when convectional storms can lead to sudden rainfalls.

Why the data matters here

Today's reading at West Arrowwood Creek is essential for understanding local flood risks, irrigation potentials, and ecological health. By comparing today's measurements to the median for this calendar day across the station's historical record—over 13 years monitored by the Water Survey of Canada—users receive a contextual snapshot that surpasses simple elevation figures. This comparison aids farmers, anglers, and community planners in making informed decisions, ensuring responsible water use and management throughout the seasons.

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.
