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 Glacier C at Alyeska Highway at Girdwood
Glacier Creek - A vital tributary of the Upper Kenai Peninsula.
Glacier Creek flows gracefully alongside the Alyeska Highway at Girdwood, Alaska, weaving through the stunning landscape of the Upper Kenai Peninsula. This waterway plays a crucial role in the regional ecosystem, offering habitat for a diverse array of wildlife and contributing to the vibrant hydrology of its surroundings.
The watershed context
Draining roughly 44 square miles, Glacier Creek captures the influx of melting snow and seasonal rains as it navigates its way through the mountainous terrain. The creek is part of a network of waterways, with neighboring peers such as the Cooper Creek near Cooper Landing and the Kenai River flowing towards Soldotna. Each of these waterways interacts within the dynamic hydrology of the Upper Kenai Peninsula, influenced by the shift of seasons that characterizes this subarctic region. Spring breakup and snowmelt drive annual flow patterns, creating opportunities for increased water levels and potential flooding, often exacerbated by ice jams.
Why the data matters here
Today's reading from the U.S. Geological Survey at Glacier Creek provides a key insight into current conditions, measured against the historical median for this date over the past nine years. The importance of comparing today's reading to the median lies in understanding fluctuations that can result from seasonal snowmelt and rain events, which are characteristic of this subarctic environment. Such data allows cottagers, anglers, and flood-watchers to make informed decisions about activities along this creek and to monitor the creek’s performance in relation to its historical context.
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.
