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.

Water Stories

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 Corn Creek Spgs at National Fish & Wildlife Hdqrs

Corn Creek Springs - A vital tributary in the Las Vegas Wash watershed.

Corn Creek Springs, located at the National Fish and Wildlife Headquarters in Nevada, serves as an important water feature within the arid landscape of the Las Vegas Wash watershed. This river, flowing amidst the subtleties of desert ecology, represents a key source of water that supports both wildlife and the surrounding environment in an area where water is often a scarce resource.

The watershed context

Corn Creek is associated with the Las Vegas Wash, a crucial drainage system that takes in runoff and return flows from the Las Vegas Valley. This area is characterized by ephemeral streams that respond significantly to seasonal weather patterns. The hydrology of the region is heavily influenced by mountain snowmelt, which typically drives spring peak flows in perennial rivers, and by localized summer thunderstorms that can lead to sudden flash floods.

In this dynamic ecosystem, Corn Creek Springs plays a unique role. The surface flows serve various ecological functions, providing necessary habitat for aquatic and terrestrial wildlife. The river also connects to several other notable channels in the vicinity, including Duck Creek and Flamingo Wash, further highlighting its relevance in the hydrological network of Southern Nevada.

Why the data matters here

Monitoring water levels and flow data is essential in understanding the health of Corn Creek Springs. With records spanning over 41 years, readings from the U.S. Geological Survey (USGS) provide valuable insights into the water body's current state. Today's measurement, when compared against the median for this calendar day, offers context that is more informative than raw elevation alone. This comparison can indicate whether current levels are typical or represent a significant deviation, helping resource managers, conservationists, and local stakeholders make informed decisions about water use and conservation in this vital desert landscape.

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.
