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 Mendenhall R at Loop Road Bridge near Auke Bay AK
Mendenhall River - a vibrant river flowing near Auke Bay.
The Mendenhall River, as it runs under the Loop Road Bridge near Auke Bay, showcases the dynamic waters typical of Alaska's coastal ecosystems. This river, located in the Lynn Canal watershed, serves as a vital waterway that supports the surrounding wildlife and landscape.
The watershed context
The Mendenhall River is a part of the broader Lynn Canal watershed, a region characterized by its unique hydrology. In this area, spring breakup and snowmelt significantly influence water levels, with flows often experiencing spikes during these periods. Given Alaska's subarctic climate, the river is also subject to deep winter low flows under ice, leading to a seasonal rhythm that varies dramatically throughout the year. The Mendenhall River flows among its peers, including Antler River and Lemon Creek, while contributing to the rich aquatic ecosystems familiar to this coastal environment.
Why the data matters here
Today's reading at Mendenhall River is an important indicator of local water conditions. Measuring river levels helps track changes in water availability, which can influence fishing, habitat health, and recreational activities nearby. Today's levels, compared to the median for this calendar day over the past year, provide critical insight for those relying on the river, including cottagers and nature enthusiasts. Monitoring these readings ensures a connection to the river’s health and supports responsible stewardship of its resources, all under the diligent efforts of the U.S. Geological Survey (USGS).
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.
