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 above Majinas Filt. Plant PR

Canal de Riego de Lajas - A crucial waterway in Southern Puerto Rico.

The Canal de Riego de Lajas serves as an essential water resource above the Majinas Filtration Plant in Puerto Rico. This river plays a significant role in agricultural irrigation and water supply within the Southern Puerto Rico watershed, supporting both local agriculture and surrounding ecosystems.

The watershed context

Southern Puerto Rico is characterized by its tropical island hydrology, marked by frequent and intense rainfall events. This hydrology can lead to flash floods, particularly during hurricane season or when tropical waves sweep across the islands. As a short basin, the Canal de Riego de Lajas can see rapid increases in water levels, sometimes dramatically within hours, highlighting the importance of monitoring for both safety and resource management.

The Canal de Riego de Lajas connects to various peers, including the Aes Intake Canal at Canal de Patillas and Canal de Juana Diaz at multiple locations. These connections enable the efficient movement of water within the region and assist in flood control and irrigation efforts across the area.

Why the data matters here

Monitoring is facilitated by the U.S. Geological Survey (USGS), which keeps track of discharge levels at this station. Regular measurements allow residents and farmers to be informed about water conditions, which can influence decisions about irrigation and flood preparedness.

Today's reading will be compared to the historical median for this date over more than 21 years of record-keeping. This context is invaluable, as it provides a reliable benchmark to understand the current conditions of the canal, helping to predict any necessary actions in response to water level changes. Such information is essential, particularly in a region where the risk of sudden flooding can impact both lives and livelihoods.

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.
