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.

Water Stories

The flood of record that was overtaken

For five years, spring 2019 was the mark every Lake Muskoka decision answered to. In April 2026 the lake went two centimeters higher - and the official books have not caught up yet.

Why the Assiniboine floods every spring

Inside the freshet cycle that puts Manitoba shorelines at risk each year - and why 2026 broke the script.

How snowpack becomes summer water

The science of snow water equivalent and why it drives the season ahead.

Flash Flood Alley: how Texas rivers rise in hours

Why Central and South Texas rivers go from gravel beds to fifty-year records in an afternoon - including July 2026 on the Nueces.

About Canal de Patillas above EL Legado Intake

Canal de Patillas above EL Legado Intake - a dynamic river flowing through Southern Puerto Rico.

The Canal de Patillas, situated above the EL Legado Intake in Puerto Rico, serves as a crucial waterway in the Southern Puerto Rico region. Regional hydrology is heavily influenced by tropical weather patterns, which contribute to a rainfall-driven landscape prone to quick rises in water levels, especially during hurricane seasons. This channel captures the runoff and precipitation that cascades down steep basins, making it a vital conduit for surface water in this vibrant ecosystem.

The watershed context

The Canal de Patillas is part of a network that includes several neighboring water bodies, such as the Aes Intake Canal and the Canal de Juana Diaz at various points. While specific drainage area details are not provided, the station's role in measuring discharge flows is invaluable, especially given the potential for rapid water level changes that characterize the region's storm systems. Understanding these connections is essential for managing water resources effectively, especially during periods of intense rainfall or tropical disturbances.

Why the data matters here

Monitoring the Canal de Patillas above EL Legado Intake is significant for various stakeholders, including local agriculture, water supply management, and flood preparedness. Today's reading from the United States Geological Survey (USGS) offers valuable insights into current water levels compared to historical medians for this date over the past 21 years. Tracking these changes not only helps in assessing the immediate water conditions but also aids in predicting future water behavior, enabling better preparedness for potential flooding and resource allocation throughout the watershed.

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.
