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 Guayanes near Yabucoa

Rio Guayanes - A dynamic river influenced by heavy rainfall.

Nestled in the vibrant landscape of Eastern Puerto Rico, Rio Guayanes flows near Yabucoa, carrying the character of a rain-driven watercourse. This river exemplifies the region's rapid hydrological responses, which are shaped by tropical downpours throughout the year.

The watershed context

The watershed surrounding Rio Guayanes spans approximately 16.4 square miles (about 42.5 square kilometers) and comprises steep basins that respond quickly to rainfall. In Puerto Rico, the hydrology is notably influenced by tropical weather patterns, leading to flash floods that can develop rapidly, particularly during hurricane season or following tropical waves. The river supports various nearby water bodies, including Lago Carite and several quebradas, interweaving them into the water network of this eastern region.

Why the data matters here

The USGS station measuring Rio Guayanes provides vital information about its current state and hydrological behavior. Today's reading will give insight into how the river is performing against historical data, taking into account its 24 years of record. This is essential for understanding the ongoing dynamics of the river, especially given the context of potentially intense rainfall events, and facilitates better preparedness for seasonal flood risks. Tracking today’s elevation compared to the median for this calendar day across the station's history offers a more reliable picture than raw levels, helping locals and officials make informed decisions regarding water management and safety.

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.
