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 Walker River at Snyder LN near Mason

Walker River - a vital waterway of the arid Great Basin.

The Walker River at Snyder Lane near Mason, Nevada, is an integral part of the Walker watershed, draining an extensive area of approximately 2,400 square miles. This river flows through the arid Great Basin, a region where the characteristics of its hydrology are shaped by seasonal cycles of mountain snowmelt and summer thunderstorms.

The watershed context

The Walker River itself is fed by mountain runoff, which showcases peak flows during the spring when the snow melts in the surrounding mountains. However, as summer brings warmer temperatures, the river's flow may fluctuate due to local thunderstorms that can occasionally unleash sudden flash floods. These events contribute to the river's dynamic nature in an environment where many channels can be ephemeral, highlighting the importance of careful water management. This complex interplay between snowfall and rainfall drives the regional hydrological patterns that influence both the ecology and the human activities surrounding the river.

Why the data matters here

Understanding the water levels at this station is crucial for various stakeholders, including local farmers, outdoor enthusiasts, and conservationists. Monitoring the river's water levels allows for better preparation against the potential for flash floods during summer storms and contributes to sustainable water management practices. Today's reading from the USGS reflects current conditions compared to the historical median for this day over the past 50 years, providing a vital context for assessing how the river is responding to its seasonal rhythms and ensuring a reliable water source for the region.

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.
