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 Mameyes near Sabana
Rio Mameyes - A vital waterway in Eastern Puerto Rico.
The Rio Mameyes flows near Sabana, Puerto Rico, serving as an essential river in the Eastern Puerto Rico watershed. Spanning an area of 6.9 square miles, this river is a crucial component of the local hydrology, which is characterized by rainfall-driven conditions that can lead to rapid flooding, particularly in the context of tropical weather events.
The watershed context
This section of the river plays a significant role in managing the surrounding landscape and ecosystem. The Eastern Puerto Rico watershed is home to various other waterways, including Lago Carite and several quebradas, such as Quebrada Grande and Quebrada Santa Catalina. These streams contribute to the overall hydrology in the area, which is defined by the steep short basins that characterize tropical island environments. Rainfall can accumulate quickly, resulting in flash floods that alter the flow dynamics of rivers like the Rio Mameyes.
Why the data matters here
Understanding the hydrological data from the USGS station at the Rio Mameyes is vital as it provides insights into water levels and discharge measurements relevant for managing local floods and ecosystem health. Today's reading from the Rio Mameyes, when compared against the historical median for this calendar day, guides residents, anglers, and flood-watchers in making informed decisions about their activities near this river. The station has been operational for over 43 years, and using this data helps contextualize current river conditions within a longer historical framework, contributing to better preparedness in this rainfall-rich 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.
