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 Grande de Loiza at Highway 183 San Lorenzo
Rio Grande de Loiza - A vital waterway in Eastern Puerto Rico.
The Rio Grande de Loiza runs through the heart of Eastern Puerto Rico, providing essential water flow to the surrounding ecosystems and communities. Its journey begins in the higher elevations and flows towards the coast, where it ultimately meets the Caribbean Sea. This river, gauged at Highway 183 in San Lorenzo, is an important part of the local hydrology, significantly influenced by Puerto Rico's tropical climate.
The watershed context
Draining approximately 41 square miles, the catchment area feeding into the Rio Grande de Loiza ensures a rapid response to rainfall. The region experiences a tropical island hydrology, characterized by occasional flash floods driven by heavy rainfalls, particularly during hurricanes and tropical waves. As a result, the river can see dramatic changes in water levels within hours, making awareness of its flow and level crucial during storm events.
Neighboring water bodies, such as Lago Carite and several small rivers and streams like Rio Bairoa and Quebrada Santa Catalina, further integrate into the rich hydrological tapestry of the area. These waterways play a vital role in maintaining the ecological balance and support a variety of habitats.
Why the data matters here
Monitoring the Rio Grande de Loiza at this location is essential for understanding the health of the river and predicting the impact of precipitation patterns year-round. Data gathered by the U.S. Geological Survey (USGS) includes discharge measurements, providing valuable insights into the river's flow dynamics.
Today's reading is vital in comparison to the median flow for this calendar day across the station's historical record spanning 37 years. By looking at this data, local residents, farmers, and flood-watchers can gauge current conditions and anticipate changes, reinforcing the significance of continuous water level tracking in this rainfall-prone 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.
