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 Sheridan R near Cordova AK
Sheridan River - a confluence of glacial influences and seasonal rhythms.
The Sheridan River flows near Cordova, Alaska, within the Lower Copper River watershed, where it's shaped by the dramatic landscape of the region. This river, like its peers, the Copper River and the Glacier River tributary, experiences the dynamic shifts of subarctic hydrology. Here, spring breakup and snowmelt herald the onset of seasonal flooding, a rhythm essential to the region's ecology.
The watershed context
While the Sheridan River itself does not have a specified drainage area, it is part of a complex network that includes the mighty Copper River, which is known for its significant glacial influences. This area presents a unique hydrological character marked by strong flows during the spring and summer, particularly as glaciers melt. These processes not only drive river levels but also play a crucial role in sediment transport and the overall health of the aquatic ecosystem.
Why the data matters here
Currently, data from the US Geological Survey (USGS) reflects that the Sheridan River has been monitored for water levels over the last four years, helping to paint a clearer picture of its flow dynamics. Understanding today's river level in comparison to the median for this calendar day provides vital insights into the river's seasonal behavior. By measuring river elevation relative to historical data, one can better gauge climatic impacts and potential flooding risks, as well as plan for fishing and recreational activities along the river. This context makes the data even more valuable for local residents, fishermen, and outdoor enthusiasts, offering a crucial tool for navigating the natural 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.
