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.

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 Saliente at Coabey near Jayuya

Rio Saliente - A vibrant river reflecting tropical island dynamics.

Nestled within the lush landscapes of Puerto Rico, the Rio Saliente flows through Coabey, near Jayuya, as part of the Cibuco-Guajataca watershed. This river is characterized by its quick response to rainfall, typical of the region's tropical island hydrology, which can lead to flash floods, particularly during hurricane seasons. The river drains approximately 8.8 square miles, encompassing a steep catchment area that can rise dramatically within hours during heavy rainfall events.

The watershed context

The Cibuco-Guajataca watershed is a diverse ecosystem, home to various wildlife and plant species thriving in the humid environment of this tropical locale. As the river channels away rainwater from the surrounding terrain, it plays a crucial role in the area's hydrology, managing the ebb and flow of water that supports both the natural environment and human communities alike. Nearby bodies of water, including the Canal de Aguadilla and Canal de Derivacion, present interesting connections for understanding water management and distribution in the region.

Why the data matters here

Today's reading at the Rio Saliente is an important measure of how weather conditions impact water levels. For instance, current values compared against the median for today over the USGS's 37 years of historical records reflect trends that are critical for local farmers, flood-watchers, and anyone engaged with the river in various capacities. Monitoring these changes helps manage the risks associated with the rapid shifts in water levels due to tropical rainfall, ensuring that residents and stakeholders can adapt to changing conditions. The USGS provides valuable insights through this data, enabling the community to remain informed and prepared.

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.
