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 Rio Grande near EL Verde

Rio Grande near El Verde - A vital waterway in Eastern Puerto Rico.

The Rio Grande, flowing near El Verde in Puerto Rico, serves as a crucial channel within the Eastern Puerto Rico watershed. This river, with a catchment area of approximately 7.3 square miles, plays an essential role in managing the dynamic hydrology of the tropical island, particularly in light of the rainfall-driven flooding that can occur throughout the year. With its steep gradients, the Rio Grande can rise quickly in response to heavy rainfall, making it a key feature for local residents and ecosystems alike.

The watershed context

Nestled in a region characterized by its intricate network of rivers and streams, the Rio Grande interacts closely with several neighboring waterways, including Lago Carite and multiple quebradas such as Quebrada Grande and Quebrada Josefina. This interconnection is vital, as it supports a diverse range of aquatic habitats while providing significant water resources for the surrounding communities. The watershed is influenced by Puerto Rico's tropical climate, which experiences intense rainfall, particularly during hurricane season, fostering a unique and vibrant ecosystem.

Why the data matters here

Understanding the water levels and discharge measurements from the Rio Grande is crucial for flood preparedness and water resource management in Eastern Puerto Rico. Today's levels should be compared against the historical median for this date, which reflects longstanding weather patterns and local hydrological responses. By referencing data from the U.S. Geological Survey (USGS), users can gain insights into both current conditions and the river's historical behavior over the past 50 years. This context allows residents, cottagers, and flood-watchers alike to make informed decisions and stay aware of potential changes in river conditions, ensuring safety and sustainability in this active tropical environment.

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.
