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 de Arecibo Blw Utuado

Rio Grande de Arecibo Blw Utuado - A vital conduit within a dynamic watershed.

The Rio Grande de Arecibo Blw Utuado serves as a significant waterway in Puerto Rico's vibrant hydrological landscape. This river flows through the Cibuco-Guajataca watershed, which plays a crucial role in managing rainfall runoff, especially in a region characterized by its subtropical climate and tropical island hydrology. Here, the confluence of persistent rainfall and steep topography creates a system that can surge rapidly, particularly during intense weather events such as hurricanes and tropical waves.

The watershed context

Draining an area of about 72 square miles, the Rio Grande de Arecibo Blw Utuado gathers water from a landscape designed to channel rainfall into swift rivers and creeks. Its peers include numerous canals and other waterways, like the Canal de Aguadilla and Lago de Guajataca, all of which contribute to the intricate drainage dynamics of the region. Together, these intersecting flow paths highlight the interconnectedness of water bodies on the island, reinforcing their importance for flood management and ecological balance.

The steep short basins in this region can lead to flash floods that may occur within hours of rainfall, making timely monitoring essential for local communities. With recent trends in climate unpredictability, understanding how these waterways behave under various conditions is more critical than ever.

Why the data matters here

Daily monitoring of the river's status is provided by the United States Geological Survey (USGS), which measures discharge and other vital statistics. Such data is vital for anticipating flooding events and ensuring community preparedness, especially in an area where rainfall can dramatically alter conditions. The gauge at the Rio Grande de Arecibo Blw Utuado has been operational for over 30 years, providing a substantial historical record to which current findings can be compared.

Today's reading provides a snapshot against the median for this calendar day, allowing us to understand the river's flow dynamics in relation to its historical patterns. This comparison is instrumental in flood risk assessment and river health analysis, delivering crucial insights that surpass simple elevation measurements. As flooding represents an ongoing concern for the surrounding communities, the data collected here proves indispensable for mitigating risks and safeguarding lives.

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.
