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 below Watson Lake near Prescott

Granite Creek below Watson Lake near Prescott - a vital flow in the Upper Verde Watershed.

Nestled in the arid landscape of Arizona, Granite Creek flows below Watson Lake near Prescott, embodying the seasonal rhythms influenced by summer storms and winter snowmelt. This river serves as an essential water source for both the local ecosystems and the community, threading through a robust landscape that is both dynamic and reliant on the unique climatic patterns of the region.

The watershed context

Granite Creek is part of the Upper Verde watershed, draining approximately 47 square miles above the station. This area is characterized by fluctuations in water flow; summer monsoon thunderstorms frequently lead to intense flash floods, while winter storms are crucial for replenishing the waterways with snowmelt. Between these events, many channels in the region can run dry, emphasizing the significance of timely precipitation in maintaining the health of this river.

Nearby water bodies, such as Beaver Creek and Big Chino Wash, contribute to the interconnected nature of water resources in the region. These peers highlight the diverse hydrological dynamics at play, shaping the landscape and supporting varied habitats within this portion of Arizona.

Why the data matters here

Keeping track of water levels in Granite Creek is essential for understanding ecological health and for managing water resources in an arid climate. The station, operated by the U.S. Geological Survey, measures vital discharge information, which helps make sense of the fluctuations that the creek experiences throughout the year.

Today’s water level reading, when compared to the median for this calendar day across a historical record of more than 27 years, provides valuable insight into the current state of Granite Creek. This context gives a clearer picture than looking at the elevation alone, helping locals, farmers, and land managers make informed decisions as they respond to the creek’s changing fortunes.

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.
