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 Canal de Juana Diaz at Lago Guayabal
Canal de Juana Diaz - A vital connection within Southern Puerto Rico's waterways.
The Canal de Juana Diaz at Lago Guayabal is an important waterway in the Southern Puerto Rico area. Flowing through a region characterized by tropical hydrology, this canal responds rapidly to rainfall, illustrating the dynamic nature of the local environment. Flash floods can occur throughout the year, particularly intensified during hurricane season and tropical waves, marking the significance of this channel in both natural and human contexts.
Why the data matters here
This station, monitored by the U.S. Geological Survey, not only tracks the water level of the Canal de Juana Diaz but also measures discharge, providing essential information for understanding the canal's hydrological behavior. Given the frequency of heavy rainfall and the steep basins in the area, real-time data from this station becomes critical in managing water-related issues, such as flooding and water quality.
Today's reading provides insight into the current state of the Canal de Juana Diaz. By comparing today's elevation to the median for this calendar day across the station's four years of historical record, we gain a context for understanding the normal fluctuations of water levels within this region. This systematic approach of comparing to historical medians allows for better decision-making and timely responses to changes in water conditions, helping to safeguard both the environment and the local community.
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.
