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 Forebay

Canal de Patillas at Forebay - A vital waterway in Southern Puerto Rico.

The Canal de Patillas at Forebay is an essential water course nestled within Southern Puerto Rico's hydrological framework. This river plays a crucial role in local water management and reflects the dynamic rainfall-driven patterns common to the region. Characterized by rapid responses to rainfall, the Canal de Patillas is particularly influenced by tropical weather systems, leading to swift fluctuations in flow and elevation.

The watershed context

The Canal de Patillas is part of a complex network of rivers and canals that includes several significant peers such as the Aes Intake Canal and multiple channels of the Canal de Juana Diaz. Although specific drainage area figures are not available, the flow dynamics are influenced by the surrounding landscape, which features steep basins and minimal time for water to accumulate. The region experiences year-round precipitation, with susceptibility to intense rainfall events linked to tropical systems, making flood risk a continuous concern.

Why the data matters here

Given the Canal's proximity to flash flood risks, real-time data on water levels and flow are crucial for local stakeholders, including residents, farmers, and emergency management officials. The operating agency, the U.S. Geological Survey (USGS), provides vital insights by measuring flow and elevation.

Today, the reading of the Canal de Patillas is essential to compare against the median for this calendar day, a figure derived from the station's historical record of over 21 years. Monitoring against the median helps identify potential flood conditions as well as natural seasonal fluctuations, ensuring that the community is prepared for the realities of living in a tropical hydrological 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.
