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 Cayaguas at Cerro Gordo
Rio Cayaguas - A vital flow in Eastern Puerto Rico.
The Rio Cayaguas meanders through Cerro Gordo, a testament to the dynamic and responsive nature of tropical island hydrology. This river is a key waterway in the Eastern Puerto Rico watershed, serving both the landscape and the communities that depend on its waters.
The watershed context
Draining roughly 10.1 square miles, the Rio Cayaguas feeds into the intricate network of rivers and streams that characterizes the eastern region of Puerto Rico. This area shares its siblings with notable waterways such as Lago Carite and the numerous Quebradas nearby. The tropical climate of Puerto Rico gives rise to a unique hydrological cycle, marked by rainfall-driven flash floods that can occur year-round. During hurricane season, intense storms can lead to rapid increases in flow, highlighting the river's capacity to respond to sudden changes in weather conditions.
Why the data matters here
Monitoring the Rio Cayaguas is essential for understanding local water conditions and for managing risks associated with floods. The U.S. Geological Survey (USGS) station at this site measures discharge, providing valuable insights into river behavior during different rainfall events. Today's reading, when compared against the median for this calendar day in the station’s 49 years of records, offers a clearer perspective on current flow conditions than raw elevation alone. Such comparisons are crucial for both residents and planners, as they help inform decisions related to safety, agriculture, and resource management in this vibrant yet vulnerable region.
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.
