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 Lake Mohave at Davis Dam, AZ-NV

Lake Mohave - A critical reservoir in the Havasu-Mohave Lakes region.

Lake Mohave, located at the Davis Dam between Arizona and Nevada, serves as an essential water body within the Havasu-Mohave Lakes watershed. This reservoir is not merely an expanse of water; it plays a vital role in managing the hydrological dynamics of the region, significantly impacted by the characteristics of arid Southwest hydrology.

The watershed context

The waters of Lake Mohave are part of a larger hydrological system that includes notable peers such as the Colorado River below Hoover Dam and Lake Havasu near Parker Dam. Draining an impressive 173,300 square miles, this catchment area influences the lake's water levels and flow patterns significantly. Here, summer monsoon thunderstorms can bring sudden, intense rainfall and are responsible for violent flash floods that can reshape the landscape. In contrast, winter storms and the melting snowpack from higher elevations contribute to water flow, highlighting the dynamic seasonal changes experienced throughout the area.

Why the data matters here

Monitoring water levels at Lake Mohave is crucial for understanding the broader trends in the Havasu-Mohave region. Today's reading offers valuable information compared against the median for this calendar day based on 19 years of historical data, as provided by the U.S. Geological Survey (USGS). This context allows users to comprehend fluctuations in water levels beyond raw elevations, illustrating how current readings stand relative to typical conditions for late in the year. Keeping an eye on these measurements is vital for those who rely on this water body for recreational activities, agricultural needs, and flood management.

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.
