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 Havasu Creek above the Mouth, near Supai

Havasu Creek - A vital tributary in the Grand Canyon's diverse ecology.

Havasu Creek, flowing near Supai, Arizona, is an important stream within the vast reaches of the Grand Canyon. Nestled among spectacular geological formations, this river plays a crucial role in supporting the unique ecosystems that thrive in this rugged landscape. With a catchment area of approximately 3,020 square miles draining into this segment, Havasu Creek feeds not only itself but also neighboring waterways, such as the Colorado River.

The watershed context

Havasu Creek lies within the renowned Grand Canyon watershed, a region characterized by its varied topography and climate. In the arid Southwest, heavy summer monsoon thunderstorms can lead to sudden and intense flash flooding, while winter storms contribute to higher flows primarily from snowmelt in the surrounding higher elevations. This dynamic hydrology creates a complex interplay between water availability and drought, which in turn influences the river's flow patterns. As upstream waters fluctuate, local flora and fauna have adapted to these variable conditions, making the river an essential component of the canyon's ecological tapestry.

Why the data matters here

Monitoring the flow of Havasu Creek is vital for understanding its health and the overall well-being of the Grand Canyon ecosystem. The U.S. Geological Survey (USGS) operates the gauge at this location, providing critical data on its discharge. Today's measurement reveals how the creek compares to historical records, particularly the median for this calendar day over 31 years. This contextualization of flow data against the median is significant, as it allows for a more nuanced understanding of the creek's current condition and its seasonal variations, rather than relying solely on raw elevation readings. This perspective is essential for cottagers, anglers, and environmentalists who depend on Havasu Creek and its waters for various recreational 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.
