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 North Fork Humboldt River at Devils Gate near Halleck

North Fork Humboldt River - A crucial artery in Nevada's high desert landscape.

The North Fork Humboldt River flows through the arid terrain of northern Nevada, offering a vital water source in a region where seasonal patterns dictate the health of both ecosystems and communities. Nestled near Devils Gate, this river captures the essence of the Great Basin's hydrology, where snowmelt from surrounding mountains leads to significant flows in spring, only to taper off as the dry summer months approach.

The watershed context

The North Fork Humboldt River is an integral part of the North Fork Humboldt watershed, draining approximately 830 square miles. It connects to nearby waterways, including Beaver Creek, which joins the North Fork Humboldt River upstream, reinforcing this river's role as a crucial source of water for the local ecosystem. Given the arid climate of the Great Basin, this watershed experiences dynamic patterns of water flow, heavily influenced by mountain snowmelt in spring and occasional summer thunderstorms that can result in localized flash floods. The waters here come to life during the melting snow, fostering essential habitats for aquatic species as well as providing irrigation for agricultural pursuits in nearby communities.

Why the data matters here

The most recent reading from the North Fork Humboldt River at Devils Gate reflects conditions vital to understanding water availability and seasonal changes. Regular monitoring is overseen by the United States Geological Survey (USGS), providing data on both water levels and discharge rates. Today’s measurement allows for comparison against the historical median for this date over the past 50 years, which is a critical factor for assessing water supply trends and making informed decisions in water management. Understanding today's flow relative to the median offers a clearer picture of current conditions and their implications for the surrounding environment, agriculture, and ecosystems in this arid landscape.

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.
