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 Souris River at Melita

Souris River at Melita - A key artery in the Central Souris watershed.

The Souris River at Melita is an important measurement station located in Manitoba, marking the flow of a significant river as it meanders through the prairie landscape. This stretch of the Souris River plays a vital role in the Central Souris - Antler watershed, which encompasses a substantial drainage area of approximately 49,600 square kilometres upstream of the station. Here, the river becomes a crucial resource for the surrounding ecosystem, as well as for community needs.

The watershed context

The Central Souris watershed surrounds the Souris River as it winds through the agricultural heart of Manitoba. This region is characterized by prairie hydrology, where spring snowmelt floods define water patterns, followed by a gradual summer recession. The Souris River contributes considerably to the overall hydrology of the area, sustaining various habitats while supporting local farmland and communities.

Despite the absence of peers mentioned in the metadata, the Souris River remains a distinctive waterway in its own right. The station's capacity to measure discharge reinforces its importance for understanding flow dynamics in the region. As snowfall melts in the spring, water levels can rise significantly, prompting close monitoring to assess impacts on local landscapes.

Why the data matters here

Understanding the flow levels at the Souris River at Melita is essential for local stakeholders, including farmers and flood-watchers who monitor agricultural conditions and potential flooding. Today's reading provides insightful context, as we compare the current water level to the median for this calendar day over 48 years of historical data. Measuring against this median keeps us grounded in the river's historical performance, providing valuable insight into current trends and potential anomalies. The Water Survey of Canada operates this measurement station, ensuring that the data collected can guide response strategies in this dynamic river system.

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.
