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.

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.

About Las Vegas Wash at Pabco Road near Henderson

Las Vegas Wash - A Vital Artery in the Desert Landscape.

Las Vegas Wash, flowing near Henderson, serves as a crucial waterway within the arid environment of Nevada. This river is part of a larger hydrological system that influences both the local ecology and the urban development surrounding Las Vegas. With a drainage area of roughly 2,125 square miles above the station, this wash plays a significant role in capturing and directing water through an otherwise dry landscape.

The watershed context

The Las Vegas Wash is a prominent feature within the Las Vegas Wash watershed, effectively channeling runoff from surrounding regions. Given the arid Great Basin hydrology, the flow of the wash is marked by significant seasonal variation. Spring usually brings peaks driven by mountain snowmelt, while summer thunderstorms can produce localized flash floods. The ephemeral nature of many surrounding channels emphasizes the importance of the Las Vegas Wash for water management, as it strategically captures and retains water during these variable conditions.

Nearby peers provide a sense of the interconnectivity of this watershed, with channels such as C-1 Channel and Flamingo Wash contributing to the overall hydrology of the area. This interaction underscores the dynamic ecosystem that thrives around these waterways, which support both wildlife and the growing community in Henderson and Greater Las Vegas.

Why the data matters here

Understanding the data from the Las Vegas Wash at Pabco Road is essential for managing local water resources effectively. The U.S. Geological Survey (USGS) monitors the wash's discharge, providing valuable insights into both current and historical water levels. Today's reading reflects ongoing conditions and can be compared against historical medians to gauge whether flows are higher or lower than typical for this time of year.

After 42 years of data collection, this information is instrumental for users ranging from city planners to residents concerned with flood risks and water availability. By comparing current readings to the median for this calendar day, stakeholders can make informed decisions, enhancing resilience in this water-scarce region.

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.
