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 Qda. Margarita at Caparra Inter. near Guaynabo
Qda. Margarita - a key tributary in Eastern Puerto Rico.
Nestled within the vibrant landscape of Eastern Puerto Rico, Qda. Margarita serves as an important tributary that contributes to the region's complex hydrology. Located near Guaynabo, this river is part of a network of waterways that reflects Puerto Rico's unique water dynamics, heavily influenced by tropical rainfall patterns and the surrounding topography.
The watershed context
Qda. Margarita flows through a steep and short basin that drains roughly 2 square miles. This configuration makes it particularly susceptible to rapid changes in flow, especially during heavy rainfall events that are characteristic of the region. The pronounced rainfall-driven hydrology often leads to flash floods, especially in the context of hurricanes and tropical waves. The nearby gauging stations, including Quebrada Santa Catalina and Rio Bairoa, bring further context to the interconnectedness of this watershed, providing vital data for monitoring water levels and flow rates throughout the broader Eastern Puerto Rico watershed.
Why the data matters here
Understanding the data from Qda. Margarita is crucial for various activities, including agriculture, recreation, and flood management. The U.S. Geological Survey (USGS), through their measurements, provides important insights into flow conditions and levels. By tracking today’s reading, water resource managers and local communities can better prepare for potential flooding events and ensure the sustainable use of this vital resource. As of today, the stream's flow data shows a measurement compared to the median for this calendar day across 13 years of historical data—this contextual comparison allows stakeholders to make informed decisions rather than relying solely on raw elevation figures.
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.
