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.

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 Portugues near Tibes

Rio Portugues - A dynamic river shaped by heavy rainfall.

The Rio Portugues flows near Tibes, nestled in the Southern Puerto Rico watershed. Known for its quick response to rainfall, this river plays a vital role in the hydrology of the region, which is characterized by tropical island dynamics. The short, steep basins in Puerto Rico allow for rapid changes in water levels, making the Rio Portugues particularly sensitive to weather events.

The watershed context

Draining approximately 7.3 square miles, the Rio Portugues contributes to an intricate network of waterways in the Southern Puerto Rico area. Its peers, including major continental channels such as the Aes Intake Canal and multiple segments of the Canal de Juana Díaz, illustrate a landscape shaped by both agriculture and urban development. In this tropical environment, rainfall drives the river's flow, with the potential for flash floods being a reality year-round.

Given the regular occurrence of hurricanes and tropical waves, the river can rise swiftly, necessitating vigilance from those living and working around its banks. The interplay between heavy rain and warm weather creates an ever-changing ecosystem, balancing the needs of local communities with the natural rhythms of the land.

Why the data matters here

Today's reading from the USGS station at Rio Portugues provides important context for gauging conditions in relation to historical records, which span over 29 years. Monitoring the river's elevation in tandem with historical median values allows stakeholders to gauge potential flooding threats and ecological changes. Understanding current data in the context of median readings for the calendar day gives a clearer picture of the river's immediate conditions and informs decisions for residents, farmers, and conservationists alike.

This careful observation ensures that the community can better prepare for the fluctuations that characterize the Rio Portugues, helping mitigate impacts from sudden weather events in this vital watershed.

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.
