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 Cave Creek Blw Cottonwood CR near Cave Creek, AZ.

Cave Creek - A seasonal river shaped by the monsoon.

Nestled in Arizona's Agua Fria watershed, Cave Creek flows below Cottonwood Creek. This river plays a vital role in the regional hydrology, especially during the summer monsoon season, when thunderstorms can trigger flash floods in an otherwise arid landscape. The creek drains roughly 82.7 square miles, drawing from the surrounding terrain to contribute to the complex environmental tapestry of the area.

The watershed context

The Agua Fria watershed is characterized by its dynamic weather patterns, driven largely by seasonal extremes. Summer storms often swell the creek dramatically due to intense rainfall events. Conversely, the winter months are influenced by snowmelt from higher altitudes, which can elevate water levels in larger tributaries of the Agua Fria River. Between these events, many channels—including portions of Cave Creek—may run dry. Such conditions illustrate the stark contrasts within the watershed and the necessity for localized water data to understand these fluctuations.

Cave Creek is part of a network of waters that include nearby peers like the Agua Fria River near Mayer and Rock Springs, as well as New River and Skunk Creek, enhancing the hydrological diversity in the region. Each of these waterways interacts with the local ecosystem, supporting various aquatic life and providing resources for flora and fauna adapted to desert conditions.

Why the data matters here

Understanding the metrics from Cave Creek is essential for anyone who interacts with the land and water here—be it farmers, cottagers, or conservationists. The data collected by the U.S. Geological Survey (USGS) helps to define current water levels, discharge measurements, and how they compare to historical trends.

Today's reading from Cave Creek will be compared to the median for this date across the station's 46 years of data. This perspective adds significant context to the snapshot of water levels, revealing not just how much water is currently flowing, but how this measurement stands against historical norms. This approach empowers users to make informed decisions based on past and present water patterns.

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.
