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 Fish Creek near Tortilla Flat
Fish Creek - A river shaped by the pulse of seasonal storms.
Fish Creek near Tortilla Flat is a notable feature in Arizona's Lower Salt watershed, where the landscape is significantly influenced by seasonal hydrology. Known for its dynamic flow patterns, Fish Creek can transition rapidly from a dry channel to a rushing stream fueled by summer monsoon storms or winter snowmelt from high elevations.
Why the data matters here.
The USGS monitors Fish Creek, and while this gauge does not measure discharge, the water level readings are crucial for understanding flood risks, particularly during the intense summer thunderstorms characteristic of the Arid Southwest. These violent weather events can lead to sudden flash floods, affecting both local ecology and communities downstream. Daily water level information is essential for cottagers, anglers, and those managing land in the area.
Today’s reading will be compared against the median for this calendar day, aiding in assessing current conditions and trends in relation to the historical record. This context becomes a powerful tool for flood preparedness and water resource management.
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.
