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 East Fork White River near Fort Apache, AZ.

East Fork White River - a dynamic stream shaped by Arizona's intense weather.

The East Fork White River near Fort Apache, Arizona, emerges as a vital waterway feeding into the larger White River system. It traverses a landscape that is defined by arid conditions, with water levels that reflect the seasonal fluctuations prevalent in the region. This river, part of a network that includes its peers—the North Fork White River, and the White River—drains a catchment of roughly 39 square miles, underscoring its importance in local hydrology.

The watershed context

The East Fork White River flows through the White watershed, an area characterized by its unique hydrological patterns. In Arizona's arid ecosystem, summer monsoon thunderstorms can bring sudden, intense rainfall, leading to flash flooding. Conversely, the winter months often see moisture in the form of snowmelt from the high-country areas, which replenishes waterways. However, between these weather events, many channels can dry up, dramatically altering flow conditions.

As such, the East Fork's flow is likely to vary significantly throughout the year, influenced by both storm events and seasonal changes. This variability is essential for managing water resources and understanding the river's ecological health.

Why the data matters here

Monitoring the East Fork White River with data from the U.S. Geological Survey (USGS) allows observers to track its flow and respond proactively to changes. Today’s readings are compared against the median for this calendar day over more than 50 years of historical record, providing crucial insight into the river's performance. This kind of comparative data is valuable, as it highlights shifts in flow that raw elevation readings do not convey. Understanding how current water levels measure against historical norms helps inform local users, from farmers to recreationists, about potential changes in water availability and flood risks.

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.
