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.

About Rio de Bayamon at Arenas
Rio de Bayamon - A vibrant watercourse in Eastern Puerto Rico.
The Rio de Bayamon flows through the heart of Eastern Puerto Rico, showcasing the dynamic hydrology of the region. This river presents a striking example of tropical island water patterns, heavily influenced by rainfall and the ever-looming threat of hurricanes and tropical waves. With a short but steep basin measuring approximately 0.4 square miles, it can respond dramatically to sudden weather changes, leading to fast-rising waters in a matter of hours.
The watershed context
The Rio de Bayamon is part of the Eastern Puerto Rico watershed, a network characterized by its numerous smaller creeks and rivers, including notable neighbors such as Lago Carite and Quebrada Margarita. This region’s rain-driven hydrology means that local rivers like the Bayamon often experience rapid fluctuations in flow, particularly during storm events. The surrounding landscape contributes to these quick shifts, as steep slopes can lead to flash floods, making monitoring and data collection crucial for local communities.
Why the data matters here
Current water levels at the Rio de Bayamon are tracked by the United States Geological Survey (USGS), which provides real-time data on this vital waterway. For instance, understanding today’s reading in relation to the median for this calendar day across the station's historical record—spanning 34 years—allows local stakeholders to gauge how current conditions compare to typical expectations for this time of year. This context is essential for those living nearby, as it helps prepare for potential flooding or other water-related events. Such data not only informs daily life but also plays a vital role in planning and safety during extreme weather occurrences.
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.
