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 Toa Vaca above Lago Toa Vaca
Rio Toa Vaca - A vital stream coursing through Southern Puerto Rico.
Rio Toa Vaca flows above Lago Toa Vaca, nestled within the Southern Puerto Rico watershed. This river, which covers a drainage area of roughly 14.2 square miles, is a primary feature of the region’s dynamic hydrology. The rainfall-driven nature of this area underlies the river's character, especially during the hurricane season when severe conditions can lead to rapid increases in water levels.
The watershed context
The Southern Puerto Rico watershed is marked by its steep, short basins, which can respond quickly to rainfall events. As a result, the river's flow can swell dramatically in a matter of hours, raising concerns about flash floods, especially during extreme weather phenomena like hurricanes and tropical waves. Nearby water sources, such as the Aes Intake Canal and the several Canal de Juana Diaz sites, also experience similar hydrological behaviors, contributing to the interconnectedness of this vibrant ecosystem. Together, they form a system that supports both agriculture and local wildlife, making it critical for the community’s livelihood.
Why the data matters here
Monitoring the Rio Toa Vaca is essential for understanding local hydrology, particularly with the USGS providing valuable data on its discharge capabilities. Rainfall can prompt rapid waters rise, making real-time data critical for flood forecasting and water resource management. Today’s reading can be compared against the median for this calendar day across the station's historical record, helping define trends and manage expectations in this flash flood-prone area. After over 37 years of data collection, the information aids in protecting communities from unexpected deluges and contributes to the wider understanding of Southern Puerto Rico's water systems.
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.
