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 Grande de Loiza at Quebrada Arenas
Rio Grande de Loiza - A vibrant river shaped by tropical rains.
The Rio Grande de Loiza flows through the lush landscapes of Eastern Puerto Rico, tracing its course near Quebrada Arenas. This river plays a pivotal role in the local hydrology, showcasing the dynamic relationship between rainfall and the waterways of the region. Given its location, the Rio Grande de Loiza is subject to the intense rainfall patterns that characterize Puerto Rico's tropical climate, particularly during hurricane seasons and tropical waves.
The watershed context
This section of the Rio Grande de Loiza drains a catchment area of approximately 6 square miles, gathering water from its surrounding environment. Its neighboring water bodies, including Lago Carite and several local quebradas, highlight the interconnectedness of the watershed. Each contributes to and influences the river's flow and ecosystem. This rainfall-driven system sees rapid changes in water levels, especially during heavy precipitation events, when the steep terrain quickly directs water into the river.
Why the data matters here
Monitoring the Rio Grande de Loiza is crucial for understanding both its ecological health and the potential for flooding. The U.S. Geological Survey (USGS) provides data on the river, making it possible for local residents, farmers, and flood-watchers to stay informed about stream flow and water levels. Today's reading at the gauge reflects current conditions in comparison to the historical median for this calendar day from over 49 years of data. This contextual understanding of the river's flow allows for better preparation and response to the sometimes severe fluctuations that can occur due to the region's weather patterns.
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.
