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 Boulder Creek near Dunphy

Boulder Creek - a vital watercourse in the arid landscape of Nevada.

Boulder Creek flows near Dunphy, nestled within the Middle Humboldt watershed. This river serves as an essential component of the region’s hydrology, where mountain snowmelt fuels spring peaks, ultimately influencing local ecosystems and water availability for neighboring communities.

The watershed context

The Middle Humboldt watershed encapsulates a variety of landscapes, characterized by its semi-arid climate. The creek is part of an intricate network of rivers, alongside its peers like the Humboldt River at Battle Mountain and Indian Creek at Crescent Valley. Boulder Creek drains a catchment area of approximately 76.7 square miles, allowing it to capture runoff from precipitation and snowmelt, delivering vital water to the surrounding ecosystems and agricultural lands downstream.

In this region, the hydrology is heavily influenced by seasonal variations. Spring brings melting snow from the mountains, leading to increased flows in Boulder Creek. Summer thunderstorms can trigger localized flash floods, showcasing the dynamic weather patterns inherent to the Great Basin. These seasonal rhythms can have a dramatic impact on water levels, creating both opportunities and challenges for water management.

Why the data matters here

Regular monitoring of Boulder Creek is crucial for understanding water availability and flood risks in this arid environment. The data from the US Geological Survey (USGS) provides real-time information that can inform local agriculture, recreation, and conservation efforts. The gauge not only measures elevation but also tracks discharge, helping users understand flow patterns and anticipate changes.

Today, Boulder Creek’s reading will be compared to the historical median for this calendar day across more than 36 years of data. This context is critical as it provides insight into how current conditions stand against typical fluctuations, offering a more reliable measure than raw elevation alone. Being informed by this data is essential for anyone engaged with this vital watercourse.

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.
