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 Lv Wash Blw Lake Las Vegas near Boulder City
Lv Wash Blw Lake Las Vegas - A vital conduit in an arid landscape.
Situated in Nevada’s unique desert environment, the Lv Wash below Lake Las Vegas serves as an important stream for the local hydrology and landscape. This stretch of river offers insight into the seasonal fluctuations of water flow typical of the Great Basin region, where mountain snowmelt contributes to the spring peaks and summer thunderstorms occasionally trigger flash floods.
The watershed context
The Lv Wash is part of the Las Vegas Wash watershed, draining roughly 2,193 square miles. This watershed encompasses several other water bodies, including notable peers such as the C-1 Channel and Flamingo Wash, contributing to the complex hydrology of the area. With the predominance of ephemeral channels, any precipitation, whether from winter snowmelt or summer storms, has a pronounced effect on water levels. The river's existence underscores the delicate balance of water resources in this arid region, where management and conservation are critical.
Why the data matters here
The data from the USGS monitoring station at Lv Wash is essential for understanding local water dynamics. Observing streamflow patterns, especially in an area that experiences both peaks and troughs in flow due to climatic variability, is crucial for a variety of stakeholders—cottage owners, farmers, and those involved in water management.
Today's reading from the monitoring station indicates the current water level compared with the median for this date across the station's historical record of over 50 years. Tracking these measurements helps inform decisions and responses to water availability, particularly vital during periods influenced by the region's characteristic arid climate.
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.
