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 Salmon R at Gustavus AK
Salmon River - a critical channel of Glacier Bay's hydrology.
The Salmon River, located at Gustavus, Alaska, is a vital watercourse flowing through the Glacier Bay area. It captures the region's dynamic hydrology, characterized by significant seasonal variations that are typical of subarctic climates. This river plays an essential role in the ecosystem and local watershed health.
The watershed context
Draining roughly 33 square miles above the monitoring station, the Salmon River is part of the larger Glacier Bay watershed. This watershed is influenced by glacial meltwater, particularly during the mid-to-late summer months when glacier-fed rivers typically reach their peak flows. During spring, the river experiences seasonal runoff from snowmelt, which can create significant flooding, often complicated by ice jams. In winter, the river flow decreases, leading to lower water levels as it becomes covered under ice. These seasonal patterns reflect the challenges and adaptations necessary for the aquatic life in this unique environment.
Why the data matters here
Today's reading from the Salmon River at Gustavus, provided by the United States Geological Survey (USGS), offers an essential snapshot for understanding current conditions. It can be compared against the median for today over the past twelve years of records, providing important context that helps local stakeholders—such as anglers, cottagers, and conservationists—assess the river's health and predict future conditions. This kind of data is crucial for managing water resources, maintaining ecological balance, and planning activities that depend on river flow.
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.
