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 near Mogul

Truckee River - A vital waterway in Nevada.

Flowing from the Sierra Nevada, the Truckee River near Mogul plays a critical role in the local hydrology of the Great Basin. This river, which spans approximately 1,035 square miles in its catchment, is a key lifeline for the surrounding community and ecology, especially during the seasonal changes of water flow.

## The watershed context The Truckee River, with its extensive watershed, is an essential water source within the arid climate of Nevada. This river is fed primarily by mountain snowmelt, contributing to the spring peaks before the summer heat triggers localized thunderstorms. During the warmer months, these storms can lead to flash floods along its stretches, an occurrence common in the region's variable climate. Local tributaries such as Davis Creek and Galena Creek enhance the river's flow, weaving a complex network that sustains diverse habitats.

Nearby water features also contribute to the ecology, with Davis Creek and Dog Creek being notable peers within the Truckee watershed. The flow dynamics of the Truckee River not only nourish local wildlife but also support recreational activities and agriculture, which rely heavily on the predictable patterns of seasonal runoff.

## Why the data matters here Monitoring data from the U.S. Geological Survey (USGS) provides crucial insights into the current hydrology of the Truckee River near Mogul. Understanding the river's discharge and current water level is vital for managing resources in this arid region, where water availability can fluctuate significantly throughout the year.

Today’s reading offers a snapshot of the river’s current state compared to historical levels. By comparing today’s measurement to the median for this calendar day over the past 34 years, stakeholders can gauge the river’s status and anticipate potential challenges or opportunities for water management. This approach helps ensure that the demands placed on the river can be balanced with the needs of the environment and local communities.

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.
