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 Rio Jacaguas Blw Highway 149 near Villalba

Rio Jacaguas - A vital watercourse in Southern Puerto Rico.

The Rio Jacaguas flows near Villalba, embodying the vibrant hydrology of Southern Puerto Rico. This river plays a crucial role in the local ecosystem, offering a natural conduit for the region's rainfall, which influences both agricultural practices and local wildlife habitats.

Why the data matters here

In an area characterized by tropical island hydrology, the Rio Jacaguas is subject to rapid changes in water levels due to rain-driven events. As rainwater accumulates within short and steep basins, flash floods can develop quickly, especially during hurricane seasons or tropical waves. Monitoring the river helps local residents and farmers prepare for these events, ensuring safety and minimizing risks to the surrounding environment.

The most recent readings capture the dynamic state of the Rio Jacaguas, which is essential for understanding its behavior and the surrounding watershed. The US Geological Survey (USGS) measures the river, but it does not currently track flow or discharge. Therefore, focusing on elevation data provides insight into the river’s condition. Today's reading is compared against the median for this calendar day across the USGS's two years of historical records, offering a better context than raw elevation figures alone when assessing changes and potential flooding risks.

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.
