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 Cedar Lake

Cedar Lake - a key feature of the Lower Saskatchewan watershed. Cedar Lake, located in Manitoba, is a significant body of water within the Lower Saskatchewan - Mouth watershed. Spanning a vast catchment area of approximately 352,000 square kilometres, this lake plays a crucial role in the local hydrology and ecology.

## The watershed context The Lower Saskatchewan watershed encompasses a diverse array of landscapes and habitats. Cedar Lake is situated in an expansive prairie region, where spring snowmelt floods often define the annual hydrological cycle. As the snow melts and water levels rise, these floods can significantly impact the local environment. Beyond the spring months, the typical pattern of summer recession sets in, leading to lower water levels and inflows.

While Cedar Lake itself does not have a direct parent river, its presence in this sizeable watershed underscores its importance in regional water dynamics. The lake contributes to both the ecological health of its surroundings and the overall hydrology of the area.

## Why the data matters here Monitoring Cedar Lake's water levels is vital for understanding the fluctuations within this significant prairie lake. The Water Survey of Canada station located near Oleson Point provides real-time data on the lake's elevation. Today's reading reflects important trends within the historical context, as it is compared against the median for this calendar day over the past 48 years of records.

Utilizing median comparisons, as opposed to just raw elevation figures, allows for a clearer understanding of current conditions in relation to typical seasonal patterns. This is essential for cottagers, anglers, and others who rely on timely updates on the lake's status throughout the year. For this reason, staying informed about Cedar Lake's levels can be crucial for making plans, managing natural resources, and ensuring safety.

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.
