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.

Shell River near Roblin Water Level

Live water level, flow, historical records and forecast for Shell River near Roblin in Canada, MB, Canada, built from official government gauge data.

About Shell River near Roblin

Shell River - a vital waterway in the heart of Manitoba’s Prairie landscape.

The Shell River, located near Roblin, thrives within the expansive Upper Assiniboine - Shell watershed, draining approximately 1,320 square kilometres above the gauge. As a key feature of Manitoba’s hydrology, the river plays an important role in the local ecosystem and water management systems.

The watershed context

The Upper Assiniboine - Shell watershed is characterized by its gently rolling terrain and agricultural landscapes, typical of the Prairie region. The Shell River flows through a landscape shaped by historical glacial activity, with its tributaries contributing to the overall health of the watershed. Nearby, water bodies such as Lake of the Prairies, along with other segments of the Shell River, help to create a network that supports both wildlife and human activity alike. Seasonal rhythms dictate that the spring snowmelt floods are a defining characteristic, contributing to peak flow periods. This natural cycle is crucial for maintaining the ecological integrity of the area.

Why the data matters here

Monitoring data from Water Survey of Canada allows for informed decision-making regarding the Shell River. The real-time gauge at Shell River near Roblin not only measures the river's level, but also provides crucial discharge data. By comparing today’s reading to the median level for this date drawn from nearly 50 years of historical records, stakeholders can better understand current conditions relative to typical seasonal trends. This approach offers insights into potential flooding events or low-flow concerns, essential for agricultural management, local residents, and those engaged in recreational activities throughout 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.
