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.

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 Pembina River at Jarvie

Pembina River at Jarvie - a key flow through the foothills.

The Pembina River at Jarvie offers a glimpse into the dynamic water systems of Alberta's foothills. This reach of the Pembina River flows through a diverse landscape characterized by its significant drainage area, which spans roughly 13,100 square kilometres upstream of the station. The river's course through this region plays a crucial role in supporting both natural ecosystems and human activities.

The watershed context

Nestled within the Lower Pembina watershed, this stretch of the Pembina River is an important tributary that interacts with neighboring water bodies like Wabash Creek near Pibroch. The river’s flow reflects the seasonal patterns typical of Alberta's hydrology. In the late spring, mountain snowmelt contributes to higher water levels, while summer convective storms can lead to sharp increases in flow due to localized rainfall.

This watershed is essential for maintaining the ecological balance in the region, supporting a variety of plant and animal life that depend on its resources. The river's flow changes throughout the seasons, providing critical habitats and watering resources for both wildlife and agricultural operations in the area.

Why the data matters here

Today's reading for the Pembina River at Jarvie is a critical indicator of the river's health and behaviour. It reflects the current conditions against a historical benchmark, as this gauge has been in operation for over 49 years. By comparing the current water level to the median for this calendar day from the Water Survey of Canada, users can better understand the flow trends, enabling informed decisions for managing the river's resources. Such comparisons offer insights into natural variations in water levels and can signal broader environmental changes in the area.

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.
