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.

Water Stories

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 Granite Creek near Prescott

Granite Creek - a vital artery in the Upper Verde Watershed.

Located near Prescott, Arizona, Granite Creek serves as an essential watercourse in the Upper Verde watershed. This natural habitat is intricately tied to the rhythm of the seasons, shaped by summer monsoon thunderstorms and winter snowmelt that give rise to varied flow patterns throughout the year. With a drainage area of approximately 36 square miles above the measurement station, Granite Creek contributes to the dynamic hydrology of the region.

The watershed context

Granite Creek flows through a landscape that often experiences dry channels between significant precipitation events. The influence of both summer thunderstorms and winter storms means that flow conditions can fluctuate dramatically, posing unique challenges and opportunities for the ecosystems and communities that depend on this waterway. The creek stands alongside other regional bodies of water such as Beaver Creek, Big Chino Wash, and Dry Beaver Creek, forming an interconnected web of waterways that support local wildlife and human activities.

Why the data matters here

Water levels and discharge measurements are crucial for understanding the health of Granite Creek and its ability to sustain local ecosystems, agriculture, and recreational activities. The U.S. Geological Survey (USGS) operates the measuring station, providing valuable data that helps gauge the current state of the creek. Today's reading is essential when compared against the median for this calendar day over the last 32 years, which offers a historical perspective on water flow. This approach allows users to detect fluctuations and potential anomalies in the creek's hydrology, enabling more informed decisions for water management and conservation efforts.

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.
