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 Coamo at Highway 14 at Coamo

Rio Coamo - A vital waterway amidst tropical rainfall.

The Rio Coamo flows through Southern Puerto Rico, presenting a dynamic river influenced by frequent rainfall. Situated at Highway 14, this river is closely watched for its response to the tropical island’s climatic conditions. As part of a lush region where flash floods can develop swiftly, the Rio Coamo connects with several peers, including the Canal de Patillas and the Canal de Juana Diaz.

The watershed context

The Rio Coamo is part of a watershed that drains approximately 43.5 square miles upstream of this monitoring station. Given the tropical climate of Puerto Rico, this river experiences intense fluctuations driven by rainfall, especially during hurricane season. The region's steep basins contribute to rapid runoff, leading to quick rises in water levels. Users of this waterway need to remain vigilant, especially during heavy storms, as localized flash floods can occur on short notice.

Why the data matters here

Continuous monitoring of the Rio Coamo is essential for various stakeholders, including local residents, farmers, and emergency agencies. This monitoring enables timely data-driven decisions, crucial in an area susceptible to extreme weather patterns. Today's water level reading will be measured against the median for this calendar day, allowing for an understanding of how current levels compare to historical data collected over the past 40 years by the U.S. Geological Survey (USGS). This context helps in assessing flood risks and managing resources effectively, as the river's responsiveness to rainfall can significantly impact local communities.

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.
