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 Tanana R at Fairbanks AK
Tanana River - A vital artery in Alaska's subarctic landscape.
The Tanana River at Fairbanks, Alaska, serves as a key waterway within the subarctic hydrology of the region. Flowing through the Tanana Flats-Tanana River watershed, this river encapsulates the seasonal shifts of the area, driven largely by spring breakup and the annual thaw. The rhythm of the year can be felt strongly here, as the landscape transforms with the melting snow and the return of flowing water.
The watershed context
The Tanana River is flanked by the rich ecology of the Tanana Flats. While exact drainage area figures are not available, the river's significance in the region is underscored by its connectivity to other water bodies, including the Tanana River at Nenana. The US Geological Survey oversees the monitoring of this quarter-mile reach of the river, providing essential data on both water levels and discharge rates.
During the spring, the melting snow leads to an increase in water levels, sometimes culminating in floods, especially in the form of ice jams that are characteristic of subarctic rivers. As summer progresses, glacier-fed rivers typically experience their peak flows, contributing to the dynamic hydrology of this region. Throughout winter, low flows prevail, often hidden beneath a layer of ice, marking the river’s annual cycle.
Why the data matters here
Today's measurement from the Tanana River at Fairbanks reflects its current conditions, which are evaluated against the historical median for this date over the last 50 years. This comparison is crucial, as it provides context to the raw elevation figures reported by the USGS. By understanding how today’s reading stacks up against the median, residents and stakeholders—whether they be cottagers, anglers, or farmers—gather valuable insights into the river's behavior. This knowledge helps inform decisions and prepares the community for the variable water conditions typical of Alaska's subarctic environment.
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.
