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 San Pedro R at Redington Bridge near Redington

San Pedro River - a vital artery through the arid Southwest.

The San Pedro River at Redington Bridge is an essential waterway within the Lower San Pedro watershed. As it meanders through this region of Arizona, it serves as a critical resource for both people and wildlife. The river captures the essence of the local hydrology, showcasing the dramatic fluctuations typical of the Southwest, from monsoon-driven floods in the summer to the variable flows often seen in the winter.

The watershed context

This section of the San Pedro River is located in a drainage area encompassing approximately 3,096 square miles. The watershed itself is known for its dynamic character; summer storms can transform the landscape with sudden and violent flash floods, while the winter months may bring slower, more steady snowmelt from nearby high country. The river is accompanied by peers, such as Aravaipa Creek, enhancing the diverse hydrological tapestry of the area.

However, the region is marked by periods of aridity, with many channels drying up between rain events. This variability impacts everything from local agriculture to wildlife populations, which depend on the river’s availability for survival.

Why the data matters here

Understanding the water data from the San Pedro River at Redington Bridge is essential for various stakeholders, including farmers, anglers, and conservationists. Deploying a continuous flow measurement from the U.S. Geological Survey allows for better anticipation of the river's behavior throughout the year. With 19 years of historical data available for reference, current readings can be compared effectively against seasonal averages.

Today's reading sheds light on current river conditions, offering crucial insight beyond mere elevation. It is compared to the median for this calendar day, providing context on flow conditions that are vital for water management purposes. This measured approach delivers a clearer understanding for those relying on the river's resources, enabling informed decisions for use and conservation.

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.
