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 Sagavanirktok R near Pump Sta 3 AK

Sagavanirktok River - An essential waterway in Alaska's subarctic landscape.

The Sagavanirktok River near Pump Station 3 is a vital waterway in Alaska, characterized by its dynamic flows driven by the unique subarctic hydrology of the region. As part of a watershed encompassing approximately 1,850 square miles, this river embodies the seasonal rhythms typical of this northern landscape, where spring breakup and snowmelt initiate annual flooding, often associated with ice jams.

The watershed context

The Sagavanirktok River forms part of a complex hydrological system influenced by the vast and rugged environment of the Alaskan interior. It runs through a landscape that is marked by extremes, experiencing deep winter low flows as the river remains covered by ice. Although the river may have limited flow during these cold months, the melting snow and ice in spring revitalizes it, contributing to its significance as a natural resource and habitat for the surrounding ecosystem.

Nearby, the Atigun River serves as a peer waterway, showcasing the interconnectedness of the region's water bodies. Together, these rivers play crucial roles in providing water resources for wildlife and influencing the local hydrology, making them key components of the northern landscape.

Why the data matters here

Monitoring the Sagavanirktok River is essential for understanding both its ecological role and the practical implications for those who utilize its resources. Today's reading from the USGS can provide insightful data on the current water conditions in the river. Each measurement is compared against the median for this day over the river's 44-year historical record, offering a valuable perspective that aids in assessing current flow and its implications on the watershed.

Compared to the median for this calendar day, today's gauge reading helps to inform water management decisions, assist in anticipating potential flooding during spring thaw, and maintain a healthy aquatic environment. By providing context beyond raw elevation, the data collected empowers communities, farmers, and stakeholders to make informed decisions in managing their water resources effectively.

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.
