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.

Flash Flood Alley: how Texas rivers rise in hours

Why Central and South Texas rivers go from gravel beds to fifty-year records in an afternoon - including July 2026 on the Nueces.

About Rio Caguitas at Villa Blanca at Caguas

Rio Caguitas - A dynamic river connecting the heart of Caguas.

The Rio Caguitas flows gracefully through the landscape of Caguas, Puerto Rico, in the Eastern Puerto Rico watershed. Measuring the hydrology of this river provides invaluable insights into the water's behavior, especially within the context of the island's tropical conditions, where rainfall can transform the river's flow dramatically in a matter of hours. The river is influenced by the tropical island hydrology that brings about swift flash floods throughout the year, particularly during hurricane seasons and tropical disturbances.

The watershed context

Draining roughly 16.6 square miles (about 43 square kilometers) above the USGS gauging station, the Rio Caguitas is part of a network of tributaries and streams that contribute to the vibrant aquatic ecosystem of the region. Neighboring streams and rivers such as the Lago Carite at Spillway and the Rio Bairoa above Bairoa enrich the ecological interconnections within this section of Caguas. The Eastern Puerto Rico watershed is characterized by steep basins that react quickly to rainfall, necessitating close monitoring of water levels for local safety and environmental stewardship.

Why the data matters here

Current data from the USGS is crucial for understanding baseline conditions of the river. Today’s water level reading provides a snapshot of the river’s behavior compared to the median for this date across 36 years of historical records. This comparison helps illuminate trends and anomalies in the river's flow, valuable for flood forecasting and resource management in the region. Tracking the state of the Rio Caguitas is essential not only for flood-watchers but also for planning agricultural activities and ensuring the ecological health of the local watershed.

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.
