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 Guajataca Blw Lago Guajataca
Rio Guajataca - A vital watercourse beneath Lago Guajataca.
Flowing steadily below Lago Guajataca, the Rio Guajataca plays a critical role in the hydrology of Puerto Rico. As a river characterized by its reliance on rainfall, it captures the essence of the region's tropical climate. The area is known for its rapid response to precipitation, typifying the challenges posed by its rainfall-driven flash floods, a phenomenon that can intensify during hurricanes and tropical waves.
## The watershed context Located within the Cibuco-Guajataca watershed, the Rio Guajataca draws from a network of nearby water bodies, including several canals and lakes which contribute to its flow. This network includes Canal de Aguadilla above Lago Ramey, and Canal de Derivacion at Lago de Guajataca, among others. Each neighbor plays a role in managing the dynamic conditions of this watercourse, particularly when heavy rains arrive, leading to swift water-level changes.
## Why the data matters here The data collected by the U.S. Geological Survey (USGS) at this station not only measures the water levels of the Rio Guajataca but also includes discharge information. By comparing today's reading to the historical median for this date, which encompasses over 42 years of record-keeping, stakeholders can gauge current conditions more accurately than simply relying on raw measurements. This comparison is essential for local cottagers, farmers, and other water users who need to anticipate flood risks or assess water availability. In understanding and interpreting today’s measurements against historical data, we reinforce our capacity to manage and respond to the unique challenges presented by tropical island hydrology.
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.
