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 Pantano Wash near Vail, AZ.

Pantano Wash - a dynamic waterway in the arid Southwest.

Nestled within Arizona's Rillito watershed, Pantano Wash captures the unique hydrology of the region. This river feeds off a vast catchment area of approximately 457 square miles, responding dynamically to the seasonal shifts common in the Southwest. The mix of summer monsoon thunderstorms and winter storms creates variable conditions, with flash floods following heavy rainfall and lower water levels during dry spells.

The watershed context

Pantano Wash near Vail connects with several local waterways, including Barrel Canyon, Brawley Wash, and Cienega Creek. These neighbors share the distinct characteristics of the Rillito watershed, where the interplay of heavy rainfall and dry conditions shapes the landscape. During summer, monsoonal rains can cause rapid rises in water levels, transforming the wash from a dry channel into a powerful stream that courses through the terrain. In the winter months, snowmelt from the high country complements the smaller winter storms, further influencing water flow.

The flash flooding phenomenon in this region showcases the need for careful observation and monitoring, especially during summer when thunderstorms can occur. As a result, the data collected at Pantano Wash is vital for understanding not only the immediate flow conditions but also the broader water availability for surrounding communities.

Why the data matters here

Real-time measurements from the Pantano Wash station, managed by the U.S. Geological Survey (USGS), provide critical insights into the river's behavior, particularly its discharge readings. Today's measurement will indicate how the current conditions stack up against historical data – this is crucial for safety assessments in the wake of extreme weather events.

The comparison of today's flow against the median value for this date across more than 37 years of records helps contextualize current conditions. This approach is essential, as evaluating the water level alone does not account for seasonal norms or historical fluctuations. Reliable data from USGS ensures that residents, farmers, and anyone engaging with this river can make informed decisions based on the natural rhythms of Pantano Wash.

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.
