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 Canas at Rio Canas

Rio Canas - A dynamic river reflecting tropical rhythms.

The Rio Canas flows through the Eastern Puerto Rico watershed, providing a vital water source for the surrounding ecosystems and communities. This river is part of a network that includes several notable peers, such as Lago Carite at Spillway and Rio Bairoa above Bairoa, Caguas. The total catchment area above the Rio Canas station measures approximately 7.5 square miles, contributing to its response to seasonal rainfall and storm systems in the region.

The watershed context

Puerto Rico's tropical island hydrology greatly influences the Rio Canas, where rainfall-driven flash floods can occur year-round. The short, steep basins typical of the region can rise rapidly during heavy rains, particularly in the height of hurricane season or with the passage of tropical waves. This dynamic hydrology means that the river can shift from calm to raging within hours, shaping not only the landscape but also the habitat and community life surrounding it.

The Eastern Puerto Rico watershed, where the Rio Canas lies, is characterized by its lush tropical foliage and diverse wildlife. The river plays a crucial role in sustaining these ecosystems, providing essential water flows that support both terrestrial and aquatic life. Observations of water levels and flow rates are vital to understanding the health of the watershed and anticipating flood events that can affect local communities.

Why the data matters here

Monitoring the Rio Canas is essential for both environmental management and public safety. The gauge at this location, operated by the U.S. Geological Survey (USGS), provides real-time data on river levels and discharge. This information is crucial for residents and local authorities, especially when weather patterns suggest impending storms.

Today’s reading from the Rio Canas shows significant information when compared to the median for this calendar day, utilizing 36 years of historical data. This comparison not only informs about the river's current status but also helps in assessing trends over time and preparing for seasonal fluctuations. Understanding these figures is crucial in an area prone to fast-changing weather and potential flooding, ensuring the safety and preparedness of the communities that rely on the Rio Canas.

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.
