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 Moenkopi Wash at Moenkopi

Moenkopi Wash - A dynamic watercourse in Arizona's arid landscape.

Moenkopi Wash meanders through the heart of Arizona, marked by its fluctuating flow that transforms dramatically in response to seasonal storms. Situated in the arid Southwest, this river’s behavior is largely governed by monsoon thunderstorms and winter snowmelt events, which can lead to sudden and intense flash flooding. This dynamic is reflective of a region where accessibility to water can shift quickly from abundance to scarcity.

The watershed context

Moenkopi Wash drains an area of approximately 1,629 square miles, gathering water from surrounding highlands during heavy rainfall and melt events. The watershed serves as a critical artery for local ecosystems and supports the surrounding flora and fauna that have adapted to this cycle of wet and dry periods. During the summer months, the intense monsoon season can lead to rapid rises in water level due to violent thunderstorms, while winter storms position the wash as a key channel for melting snow that may feed larger downstream rivers.

Why the data matters here

Monitoring the flow at Moenkopi Wash is essential for understanding the hydrological patterns characteristic of arid landscapes. Today's reading from the U.S. Geological Survey provides vital context, as it is compared to the historical median for this calendar day over the past 50 years. This comparison helps distinguish between normal fluctuations and potentially concerning trends. In this environment, where many channels may run dry between significant rainfall events, knowing where the water stands today can inform prepared responses to both drought and flooding, aligning land management strategies and enhancing public safety.

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.
