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 S Twin River near Round Mountain
S Twin River - A seasonal flow shaped by mountain snowmelt.
S Twin River flows through the Northern Big Smoky Valley in Nevada, showcasing the hydrological characteristics of the arid Great Basin. This river is a vital vein for the local ecology, responding dynamically to seasonal changes that are primarily driven by snowmelt from the surrounding mountains.
The watershed context
Draining roughly 20 square miles, S Twin River is fed by mountain runoff that peaks in spring, specifically from melting snow. This flow diminishes in the heat of the summer, when evaporation rates increase and the region experiences occasional thunderstorms that may lead to local flash floods. However, much of the river’s flow diminishes seasonally, reminding those who rely on it for agricultural or recreational purposes of the region's unique climatic rhythms.
The ephemeral nature of many Great Basin channels means that while S Twin River can run strongly during peak seasons, it may also experience low water levels as the summer progresses. This fluctuation can greatly affect the surrounding landscape and the biodiversity it sustains.
Why the data matters here
Continuous monitoring of the S Twin River is performed by the U.S. Geological Survey, which provides valuable data on the river's discharge. Today's reading offers insights into the current flow conditions, which can be compared against the historical median for the date across the station's record of more than 50 years. This context is essential for understanding how today's conditions measure up to typical seasonal trends, as it provides a more nuanced picture than raw elevation data alone. Such information is valuable for local cottagers, anglers, and farmers, as it can influence decision-making concerning water use, land management, and recreational 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.
