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 Humboldt River at Comus

Humboldt River at Comus - A vital artery of the Middle Humboldt watershed.

The Humboldt River flows through Nevada's arid landscape, and the Comus gauge plays a crucial role in monitoring this dynamic river system. Draining roughly 12,220 square miles, the Humboldt River supports diverse ecological systems while also serving as a water source for local agriculture and communities. Situated within the Middle Humboldt watershed, this segment of the river offers insights into the seasonal hydrology typical of the Great Basin region, characterized by spring peaks driven by mountain snowmelt and occasional summer thunderstorms unleashing localized flash floods.

The watershed context

As part of the Middle Humboldt watershed, the Humboldt River at Comus is surrounded by a varied network of tributaries, including Boulder Creek near Dunphy and Indian Creek at Crescent Valley. This watershed, like many in the arid Great Basin, experiences significant water fluctuations due to climatic conditions. Snowmelt contributes to the river's flow primarily in spring, while summer can bring increased precipitation from thunderstorms that may lead to flash flooding in ephemeral channels. These variations highlight the importance of accurate water monitoring to understand and respond to shifting river dynamics.

Why the data matters here

Current measurements from the U.S. Geological Survey indicate an essential snapshot of the river's status at Comus. By comparing today's reading against the median for this calendar day over the past 50 years, stakeholders gain a clear perspective on the river's condition. This method surpasses raw elevation figures, as it contextualizes the current flow relative to historical data, thereby helping to inform irrigation practices for farmers, navigation for local anglers, and flood preparedness for residents.

Understanding the Humboldt River's flow and trends provides critical information for those relying on this waterway for sustenance and safety in an environment shaped by both seasonal rhythms and sudden weather changes.

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.
