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 Truckee River at Glendale Ave near Sparks

Truckee River - A vital watercourse of the Truckee watershed.

The Truckee River flows through a diverse landscape, cutting its path near Sparks in Nevada. As a crucial river within the Truckee watershed, it is shaped by the unique hydrology of the arid Great Basin. Seasonal snowmelt from the nearby mountains typically drives peaks in the river's flow during spring, while summer brings the potential for unpredictable thunderstorms that can lead to local flash floods.

The watershed context

This section of the Truckee River is influenced by a drainage area of roughly 1,064 square miles upstream of the gauge. This expanse plays a key role in supporting the river's health and flow, feeding it during critical periods of the year. The surrounding watershed includes several other streams and creeks that complement the Truckee's water supply, such as Davis Creek, Dog Creek, and Galena Creek, all contributing to the ecological balance of the area.

Why the data matters here

Today's measurement of the Truckee River at Glendale Ave stands vital for anyone monitoring the river's health and behavior. This data, collected by the U.S. Geological Survey, allows us to compare current flow levels against the historical median for this date over the twelve years of record keeping. Such comparisons provide insights that raw elevation figures alone cannot offer, enabling better understanding and anticipation of the river's patterns. It’s an essential tool for cottagers, anglers, and local residents who depend on the Truckee for various activities.

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.
