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.

Why Central and South Texas rivers go from gravel beds to fifty-year records in an afternoon - including July 2026 on the Nueces.

About W Walker River near Hudson

W Walker River - a dynamic watercourse in Nevada.

The W Walker River near Hudson flows through the arid landscape of Nevada, weaving through the West Walker watershed. This river, about 964 square miles in catchment area, plays a crucial role within its ecological context, influenced by the unique hydrology of the Great Basin. Although the river is primarily fed by snowmelt in spring, it can be subject to summer thunderstorms that may lead to flash floods, particularly in more ephemeral channels nearby.

The watershed context

This river is part of the West Walker watershed, and its surroundings include various tributaries and nearby water bodies such as Topaz Lake. The West Walker watershed is characterized by its interplay of perennial and ephemeral streams, where water levels can fluctuate dramatically. The high variability in flow patterns is typical for the region, particularly influenced by the seasonal melt of mountain snow and localized precipitation events.

The W Walker River is part of the interconnected hydrological system, providing crucial water for the local ecosystem while supporting agricultural and recreational activities in the area. As a perennial river, it forms a reliable source of water for the landscape, especially critical during the drier months when other streams may experience reductions in flow or cease to flow entirely.

Why the data matters here

Monitoring water levels at the W Walker River is essential for understanding its environmental health and hydrological dynamics. The U.S. Geological Survey (USGS) provides real-time measurements of the river's discharge, which offers insights into the seasonal variations and overall water availability for the surrounding region.

Today’s reading is a key indicator, as it is compared against the median elevation for this calendar day over the past 50 years of record-keeping. This comparison allows observers to gauge how current conditions stack up against historical trends, providing a clearer understanding of variability due to seasonal rhythms or potential impact from weather events. These insights are invaluable, not only for local residents and farmers but also for managing the ecological balance in this unique environment.

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.
