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 near Hyder AK
Salmon River - a vital waterway in Alaska's subarctic expanse.
The Salmon River, located near Hyder, Alaska, is an essential component of the Headwaters Portland Canal watershed. This river flows through a rugged landscape marked by the influences of subarctic hydrology. Here, annual water levels are significantly shaped by the patterns of spring breakup and snowmelt, which dominate the flood cycle, particularly in the early months of the year. Seasonal shifts lead to significant flow variations that create a dynamic environment well-suited for various aquatic habitats.
The watershed context
Draining approximately 107 square miles, the Salmon River supports a range of ecological interactions along its banks. The pulse of this river responds keenly to the subarctic climate, experiencing sharp flow increases during the spring as melting snow enters the waterways, contributing to the river's vitality. As the summer approaches, flow levels fluctuate, often peaking in mid-to-late summer for glacier-fed rivers in surrounding areas. Conversely, during the deep winter months, the river may experience significantly reduced flows as the waters freeze under ice cover.
The Salmon River's positioning within the Headwaters Portland Canal watershed emphasizes its relevance in the region's hydrological framework, serving as a tributary that supports both local ecosystems and contributes to the broader hydrology of Southeast Alaska.
Why the data matters here
Today's measurement of the Salmon River provides critical insights into its current status. To understand how today's reading compares, we note that it reflects an essential part of the historical context, as it has been recorded over 17 years by the U.S. Geological Survey (USGS). Comparing current river levels against the median for this date informs us of trends and anomalies, important factors for local anglers, farmers, and residents. Monitoring these fluctuations helps reveal vital information regarding ecological health and flood risks, making these metrics invaluable for everyone who relies on this dynamic subarctic river.
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.
