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 San Pedro River at Palominas, AZ.
San Pedro River - A vital lifeline in the Arizona landscape.
The San Pedro River at Palominas, Arizona, flows through an arid region characterized by dramatic seasonal shifts. This river is a significant contributor to the hydrology of the Upper San Pedro watershed, which stretches over a vast area. Serving as a principal water source for local flora and fauna, the San Pedro River plays a crucial role in sustaining wildlife and supporting agriculture in this predominantly dry landscape.
The watershed context
The San Pedro River rises in the highlands of northern Mexico, traversing through Arizona before it joins the Gila River. This section at Palominas is fed by seasonal rainfall patterns prevalent in the Arid Southwest, where summer monsoon thunderstorms can bring intense precipitation, causing flash floods that rapidly alter the river's flow. In contrast, during winter months, snowmelt from higher elevations feeds the river more gradually, reinforcing its flow when rain is scarce. Below Palominas, the river's flow is complemented by adjacent tributaries and springs, with notable peers including the Babocomari River near Tombstone and Garden Canyon near Fort Huachuca.
Why the data matters here
Understanding the flow of the San Pedro River is essential for local water management, agriculture, and flood control. Currently, the USGS station measures both the river’s elevation and discharge, providing valuable data that helps assess the river's health and behavior during different seasons. Today's reading is a critical number for comparison: it reflects the elevation of the river against the median elevation for this calendar day across the station's historical record of over 50 years. This standard is essential for interpreting the current water level effectively, as it contextualizes today's measurement relative to past conditions, enabling informed decisions for cottagers, farmers, and conservationists who depend on this river system.
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.
