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 Magaguadavic River at Elmcroft

Magaguadavic River - A vital flow through New Brunswick.

The Magaguadavic River at Elmcroft serves as an important waterway in New Brunswick, covering a substantial catchment of approximately 1,420 square kilometres. This river is part of the Magaguadavic watershed, which connects broader ecological and hydrological networks while supporting diverse life forms along its banks. With peer rivers like the Lepreau River and nearby Magaguadavic Lake, this river also plays a crucial role in the regional hydrology of Atlantic Canada.

The watershed context

The Magaguadavic River flows through a landscape shaped by the local climate and topography. In spring, the region experiences a freshet due to snowmelt, which can lead to an increased risk of ice jams on the major rivers. Following the warm months, fall rain can contribute to flood events, highlighting the dynamic nature of water flow in this area. With the river cradled by the surrounding environment, it reflects the seasonal rhythms typical of New Brunswick, including the transition to winter ice cover.

Why the data matters here

Monitoring the Magaguadavic River's water levels is crucial for managing both ecological integrity and potential flood risks. Today's measurement serves as a point of comparison with historical records, specifically against the median for this calendar day across the station's 108 years of data. The Water Survey of Canada provides these insights, helping local stakeholders understand changes in the river's flow patterns and anticipate shifts in water levels. By focusing on this historical perspective rather than merely a snapshot elevation, we gain a more reliable view of the river's current state and its context within broader hydrological trends.

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.
