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 Maggie Creek at Carlin

Maggie Creek - a vital flow in the Upper Humboldt watershed.

Maggie Creek flows through the heart of northern Nevada, sustaining local ecosystems and communities while serving as a key tributary in the Upper Humboldt watershed. This river, gauged at Carlin, showcases the characteristic hydrology of the arid Great Basin region where water management and observance are crucial in such an unpredictable climate.

The watershed context

The Upper Humboldt watershed, which includes Maggie Creek, is significant for its diverse hydrology characterized by seasonal variability. Spring time typically sees an influx of water as mountain snowmelt from surrounding areas contributes to elevated river levels. In contrast, the summer months can bring localized thunderstorms, sometimes resulting in flash floods, while many of the channels in the area may only flow intermittently.

Maggie Creek's gauge, managed by the U.S. Geological Survey (USGS), monitors the river's discharge and provides important data on its flow patterns. This specific site drains approximately 396 square miles upstream, collecting runoff and precipitation that nourish the surrounding environment. This river connects with several nearby waterways, including Hanks Creek and the Humboldt River, reinforcing its role in the regional hydrology.

Why the data matters here

Monitoring Maggie Creek is essential for understanding water availability and distribution in this arid region. Current data not only reflects ongoing conditions but also showcases how they compare to historical trends—allowing for better resource management and preparation for potential flooding events.

Today's reading at Maggie Creek is crucial, as assessing current flow levels against the median for this date within the 34 years of available data can indicate significant changes in water availability. This context is invaluable to researchers, local farmers, and other community members who rely on accurate water information to guide their activities. The USGS provides this vital data, ensuring that those who depend on the river have the information they need to navigate the dynamic conditions that characterize the Upper Humboldt watershed.

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.
