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.

About Carson River Blw Lahontan Reservoir near Fallon
Carson River - A vital flow for the Carson Desert.
The Carson River below Lahontan Reservoir near Fallon is a significant watercourse that serves as a critical lifeline in the arid environment of the Carson Desert. With a substantial catchment area of approximately 1,801 square miles, this river plays an essential role in managing water resources for local communities, agriculture, and wildlife.
The watershed context
The Carson Desert watershed encompasses diverse landscapes, where mountain snowmelt contributes to the river's spring peaks. This seasonal rhythm is typical of the region, as the gradual meltwater helps to sustain creek and river flows ahead of the dry season. Summer months often bring thunderstorms that can trigger localized flash floods, creating a dynamic hydrological environment. The Carson River, alongside peers such as Carson River at Tarzyn Road and the Truckee Canal, shapes the ecological framework of this arid landscape, providing essential water for both human and natural ecosystems.
Why the data matters here
Understanding the current conditions of the Carson River below Lahontan Reservoir is crucial for managing water resources effectively in this semi-arid region. Today's water reading allows us to compare with the median for this calendar day based on over 50 years of historical data from the U.S. Geological Survey (USGS). This level of comparison is more informative than raw elevation alone, as it highlights trends in water availability and helps inform agricultural planning, flood management, and conservation efforts. As seasonal patterns evolve, maintaining awareness of water levels in the Carson River can provide insights into broader environmental changes affecting the entire Carson Desert watershed.
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.
