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 Patillas at Intake 123, Salinas PR

Canal de Patillas - A vital irrigation channel in Southern Puerto Rico.

The Canal de Patillas at Intake 123 plays an essential role in the Southern Puerto Rico watershed, acting as a critical irrigation source for the surrounding agricultural lands. Given Puerto Rico's tropical climate, this canal is part of an intricate network that captures and channels rainfall to support local farming needs and sustain the ecosystems in the area.

The watershed context

Southern Puerto Rico typically experiences a rainfall-driven hydrology, with short basins that can respond rapidly to weather events. The Canal de Patillas is entrenched in this dynamic environment, where flash floods can occur, particularly during hurricane season and severe tropical waves. These conditions often lead to significant shifts in water levels across the region, reflecting the urgency and importance of monitoring such waterways.

Navigating the array of peer waterways, the Canal de Patillas connects with other significant channels such as the Aes Intake Canal in Guayama and the Canal de Juana Diaz, which is vital for irrigation and flood management across the area. These connections enhance the resilience of the agricultural landscape and help manage the rapid influx of water during intense rainfall events.

Why the data matters here

Monitoring data from the Canal de Patillas is vital for understanding the water levels that directly influence agricultural practices and flood management in the region. The U.S. Geological Survey (USGS) maintains regular measurements at this site, and today's reading serves as an indicator of current conditions against the historical median for this date, covering nearly 18 years of records. This comparison is crucial, as it helps stakeholders assess the immediate and long-term impacts of rainfall fluctuations on both farm viability and community safety.

By relying on data rather than raw elevation figures, local farmers, flood-watchers, and decision-makers can better prepare for the impacts that rainfall-driven events bring to the Southern Puerto Rico region.

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.
