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 Truckee River near Tracy
Truckee River - A vital waterway in Nevada.
The Truckee River near Tracy is an essential tributary of the larger Truckee watershed, draining an expansive catchment area of approximately 1,580 square miles. This river often sees fluctuations in flow due to the unique hydrology of the arid Great Basin region, where mountain snowmelt dictates seasonal water availability and summer thunderstorms can lead to sudden and intense runoff.
The watershed context
The Truckee River flows through diverse landscapes, offering connectivity for many smaller streams and creeks. Among its peers are notable water bodies such as Davis Creek at Davis Creek Campground Road and Dog Creek at Verdi. Residents and visitors alike rely on these waters for various recreational activities and as a natural resource. Mountain snowmelt typically fuels the river's flow in spring, leading to significant peak levels, which can taper off in the summer months as evaporation and reduced inflow take hold. The combination of seasonal changes and local thunderstorms makes monitoring this river particularly important for flood awareness and water management.
Why the data matters here
Today's reading, published by the U.S. Geological Survey, provides crucial insight into the current state of the Truckee River at Tracy. By comparing today’s flow level against the median for this day over the station's 29 years of records, stakeholders can gauge how the river is behaving relative to historical patterns. This comparison not only adds context to the raw elevation but also aids in identifying trends driven by seasonal variations in the Great Basin. Understanding the current discharge data helps farmers, anglers, and all who rely on the river navigate the dynamic hydrology of this vital waterway.
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.
