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.

About Canal de Riego de Lajas at BO. Palmarejo near Lajas

Canal de Riego de Lajas - A vital irrigation artery in Southern Puerto Rico.

The Canal de Riego de Lajas, located at BO. Palmarejo near Lajas, serves as an important irrigation channel in the vibrant agricultural landscape of Southern Puerto Rico. This waterway is designed to transport water effectively, supporting local farming and helping to sustain the region's economy.

The watershed context

The Canal de Riego de Lajas draws from the broader Southern Puerto Rico watershed, an area characterized by its rainfall-driven hydrology. Rainfall is abundant here throughout the year, contributing to the risk of flash floods, particularly during tropical storms and hurricanes. These weather events can escalate quickly, with steep short basins in the region capable of rising dramatically in a matter of hours. Effective management of irrigation through channels like the Canal de Riego de Lajas becomes crucial in such a dynamic environment, where water levels can fluctuate significantly.

This canal is closely related to several other irrigation systems and waterways in the region, including the Aes Intake Canal at Canal de Patillas and the Canal de Guamani Oeste at Highway 15 Guayama. Together, they form an intricate network that supports agricultural activities throughout Southern Puerto Rico.

Why the data matters here

Today's reading from the Canal de Riego de Lajas is a key indicator of current water conditions. The U.S. Geological Survey (USGS) provides continuous monitoring of this site, which not only helps track water levels but also measures discharge. This ongoing observation, especially over the past 26 years, allows for meaningful comparisons against historical data, specifically the median for this particular calendar day. Understanding how today's measurements stack up against those averages is vital—it provides a clearer picture of real-time conditions and alerts local farmers and residents to changes that could impact their activities and safety.

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.
