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 Blw Lago Loco Dam Yauco PR

Canal de Riego de Lajas Blw Lago Loco Dam Yauco PR - A vital artery in Southern Puerto Rico's hydrology.

The Canal de Riego de Lajas is an essential waterway located below the Lago Loco Dam in Yauco, Puerto Rico. Serving as a crucial irrigation canal, it plays a significant role in managing the water supply for agricultural activities in the surrounding areas. This waterway is part of the dynamic hydrology that characterizes Southern Puerto Rico, where rainfall drives hydrological activity, leading to flash floods, particularly during tropical storms and hurricane seasons.

The watershed context

This canal is situated within the Southern Puerto Rico watershed, a region shaped by its unique tropical climate that brings year-round rainfall, contributing to a highly efficient runoff system. The area is known for its steep short basins, which can respond rapidly to precipitation events. Such characteristics make the Canal de Riego de Lajas an important part of local water management strategies, especially during extreme weather patterns that can create sudden surges of water.

Nearby, the Canal de Riego de Lajas has several peers, including the Aes Intake Canal at Canal de Patillas and multiple reaches of the Canal de Juana Diaz. Their proximity highlights a network of water management systems designed to divert and control water flow for agricultural and communal use. These canals collaborate to effectively manage the abundant rainfall that typically sweeps through Southern Puerto Rico.

Why the data matters here

Data from the Canal de Riego de Lajas, monitored by the U.S. Geological Survey, is critical for understanding both current and historical hydrological conditions. The station measures discharge, providing vital insights into water levels and flow rates that can indicate changes in weather patterns or flood risks. This information is particularly relevant given the region's susceptibility to flash floods, which can occur rapidly with little warning.

Today’s reading from the Canal de Riego de Lajas is assessed against the median for this calendar day across its historical record of 26 years. This comparison is more informative than simply looking at the raw elevation, as it allows for a nuanced understanding of current conditions in relation to typical patterns, thereby equipping residents and farmers with the knowledge needed for effective water management and safety measures.

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.
