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.

Rio Cibuco at Vega Baja Water Level

Live river level, flow, historical records and forecast for Rio Cibuco at Vega Baja in PR, United States, built from official government gauge data.

About Rio Cibuco at Vega Baja

Rio Cibuco - a dynamic river shaped by island storms and rainfall.

The Rio Cibuco flows through Vega Baja in Puerto Rico, encompassing a lively stretch influenced largely by tropical climatic patterns. This river is part of the Cibuco-Guajataca watershed, which is characterized by its quick rise and swift fluctuations. With an upper catchment area draining roughly 85.2 square miles, the river showcases the relationship between the surrounding environment and its water resources.

The watershed context

The Cibuco-Guajataca watershed is one where rainfall drives its hydrology year-round, creating conditions that can lead to rapid water level changes. These alterations are especially pronounced during hurricane events or tropical waves, when sudden downpours can result in flash floods that reshape the landscape almost overnight. Given the steepness of the basins, water can surge quickly, making monitoring critical in managing risks associated with flooding.

The Rio Cibuco is well-regarded in the region and is accompanied by several peers, including the Canal de Aguadilla and the Canal de Derivacion at Lago de Guajataca. These streams contribute to the complex fabric of waterways, all of which work together to transport rainfall runoff toward larger bodies of water.

Why the data matters here

Understanding the current water levels and flow rates of the Rio Cibuco is essential for locals and visitors alike. The U.S. Geological Survey (USGS) station provides crucial data regarding the river's behavior over time, including its discharge measurements. With a historical record spanning over 50 years, this data serves as a cornerstone for assessing both immediate conditions and long-term trends.

Today's reading of the Rio Cibuco compared to the median for this calendar day is vital. This metric helps gauge the river's current status in relation to its historical normal, providing insight into whether it is experiencing elevated or reduced water levels. Monitoring such changes is imperative to ensure safety for communities at risk of flooding and to inform agricultural practices in the 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.
