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 Loco at Las Latas near la Joya near Guanica
Rio Loco - A dynamic river shaped by tropical rains.
The Rio Loco at Las Latas near la Joya flows through the heart of Southern Puerto Rico, where intense rainfall patterns drive this vibrant watercourse. Known for its swift responses to weather events, the river is a vital component of the region's hydrology, especially during hurricane season and tropical waves when flash floods can happen with little warning.
The watershed context
Flowing through a steep and swift landscape, the Rio Loco is a product of the tropical island climate that characterizes Puerto Rico. Rainfall is abundant throughout the year, leading to quickly rising waters that can surge dramatically in the wake of storms. Although specific drainage area figures are not available for this station, the river stands among the many waterways in Southern Puerto Rico that collectively contribute to the complex watershed system.
Nearby, the river connects to a network of contributing canals and smaller tributaries, including the Aes Intake Canal and the Canal de Juana Diaz. Together, these waterways play essential roles in managing the region's water resources, from supplying water for agriculture to helping mitigate flood risks.
Why the data matters here
Today's reading at the Rio Loco, recent data published by the U.S. Geological Survey, offers insights into the current state of this river and the conditions impacting it. By comparing today's measurement against the median for this calendar day across the station's historical record of more than 20 years, we gain a clearer perspective on the river's trends and fluctuations. This contextualizing approach provides valuable information to local stakeholders, such as farmers and residents, helping them prepare for potential flooding events and manage their water usage effectively. Understanding these patterns is crucial in this tropical setting, where rivers like the Rio Loco can experience extreme changes in flow within a short time frame.
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.
