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 Copper R at Million Dollar Bridge near Cordova AK
Copper River - A key waterway of the Alaskan landscape.
The Copper River flows through the striking landscapes of Alaska, near the town of Cordova. With its vast drainage area and vital connections to local ecology, this river is a crucial resource for both the environment and the communities nestled along its banks. The Copper River at the Million Dollar Bridge is an important monitoring site, capturing both the hydrological state and the natural rhythms that define this subarctic region.
The watershed context
Draining approximately 24,030 square miles, the Copper River basin plays a vital role in supporting the diverse ecosystems of the area. Surrounding waterways such as Copper River Delta, Glacier River, and Sheridan River collectively enhance the hydrological tapestry of this region. While the Copper River is not glacier-fed, it is influenced by the annual cycle of snowmelt and spring breakup, which significantly affect its flow levels. During the spring, these processes can lead to notable spikes in water levels and potential flooding, often exacerbated by ice jams.
Why the data matters here
Today, the Copper River’s gauge reading, tracked by the U.S. Geological Survey, is essential for understanding local hydrological dynamics. By comparing this reading to the median elevation for the same calendar day across the station's 38-year historical record, we gain valuable insights into current conditions. This benchmark is crucial because it provides context to water level measurements and helps identify trends or anomalies in the river's behavior. As flows can fluctuate significantly during the subarctic winter, when low flows are typical under ice, staying informed on today’s conditions is especially relevant to those who rely on the river for fishing, local transportation, and ecosystem health.
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.
