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.

Rio de la Plata - A dynamic river shaped by rainfall.
Surging through the heart of Eastern Puerto Rico, the Rio de la Plata flows with fervor, particularly during the region's tropical rainfall patterns. This river is part of a vibrant watershed that plays a crucial role in the surrounding ecosystem and the communities that rely on its waters.
The Rio de la Plata, stretching beneath the La Plata Damsite, serves as an essential vein for the local environment, draining an upstream catchment area of approximately 181 square miles. This expansive drainage contributes to the river's responsiveness to precipitation. In Puerto Rico's tropical climate, the hydrology is driven predominantly by rainfall, leading to rapid fluctuations in flow levels. Rainfall can lead to flash flooding in a matter of hours, especially during periods of intense weather events such as hurricanes and tropical waves.
Nearby water bodies, including Lago Carite and Quebrada Margarita, further enhance this interconnected hydrological network, each contributing to the richness of the ecosystem. These neighboring waterways exemplify how the region comes alive with dynamic water movement, supporting both ecological diversity and human activity.
Monitoring the Rio de la Plata Blw la Plata Damsite is essential for understanding water levels and the river's flow patterns, particularly given the area's susceptibility to flash floods. The river's historical data, collected over 37 years by the U.S. Geological Survey, provides valuable insights for local residents, farmers, and emergency management services.
Current data readings compared to the median for this calendar day allow for an informed assessment of flow conditions. This approach surpasses raw elevation readings by contextualizing them within the river’s historical behavior. The information helps in anticipating potential flooding, making it vital for anyone who depends on the river or ventures into its vicinity. Understanding these dynamics supports better preparedness and response strategies in a region where rainfall can dramatically shape daily life.
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.
