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 Lajas Filt Plant Lajas

Canal de Riego de Lajas - a vital conduit for water management in Southern Puerto Rico.

The Canal de Riego de Lajas is an integral waterway in the Southern Puerto Rico region, serving both agricultural needs and local ecosystems. This river flows below the Lajas filtration plant, playing a crucial role in managing water supplies and ensuring the availability of fresh water for surrounding agricultural lands.

The watershed context

Located within the Southern Puerto Rico watershed, the Canal de Riego de Lajas is surrounded by various other water bodies, including the Aes Intake Canal at Canal de Patillas, the Canal de Guamani Oeste, and multiple sections of the Canal de Juana Diaz. These waterways work in concert to respond to the region's unique rainfall-driven hydrology. The tropical climate of Puerto Rico leads to significant and often rapid water fluctuations, particularly during flash floods triggered by seasonal heavy rains, hurricanes, and tropical waves.

This dynamic environment necessitates careful monitoring and management of water levels. The Canal de Riego de Lajas is well-equipped for the task, with discharge measurements facilitated by the U.S. Geological Survey (USGS). Such oversight ensures that local farmers and stakeholders can access real-time data to inform their water management decisions during periods of both high intensity and scarcity.

Why the data matters here

Monitoring the Canal de Riego de Lajas is essential due to its functional significance in the watershed and the broader context of Puerto Rico's hydrology. The real-time data provided by the USGS allows for improved agricultural planning and emergency response strategies, particularly in anticipation of torrential rainfall and potential flooding events.

Considering the 26 years of historical records, today's reading informs us about current conditions compared to the median for this date, a meaningful benchmark. This insight transcends mere elevation numbers, as it forms part of a broader pattern of water behavior in the region. By understanding how today's measurements stack up against historical averages, stakeholders can better assess risks and opportunities for water use in this vital agricultural zone.

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.
