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.
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.

Live river level, flow, historical records and forecast for Rio Tanama near Utuado in PR, United States, built from official government gauge data.
Rio Tanama - A vital watercourse in Utuado.
The Rio Tanama flows gracefully near Utuado, Puerto Rico, serving as an important natural feature within the Cibuco-Guajataca watershed. With a drainage area of roughly 18 square miles upstream of the gauging station, this river plays a crucial role in the region's hydrology, influenced heavily by tropical island conditions.
The Cibuco-Guajataca watershed encompasses a variety of waterways, including several peers such as the Canal de Aguadilla and Canal de Derivacion at Lago de Guajataca. This interconnected system reflects the dynamic nature of rainfall-driven flows typical in this region, where short basins can rise in response to intense rainfall, particularly during hurricane season and tropical waves. The Rio Tanama stands as an integral part of this network, capturing and redistributing water across the landscape.
Today, the USGS provides a reading that reflects the current conditions of the Rio Tanama. Monitoring this river is crucial, especially given the potential for flash floods, which can develop quickly due to heavy rainfall. Knowing how today's water level compares against the historical median for this date gives residents, farmers, and emergency planners valuable insight into the river's behavior. By understanding the river's flow patterns over the last 50 years, stakeholders can better prepare for the seasonal rhythms that bring both lush growth and potential hazards, contributing to effective water management in this vibrant community.
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.
