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 Iliamna R near Pedro Bay AK
Iliamna River - A vital artery of the Lake Iliamna watershed.
The Iliamna River near Pedro Bay, Alaska, is an important waterway that contributes to the extensive hydrology of Lake Iliamna. This river serves as a key channel, conveying water through a catchment that spans approximately 129 square miles. The river is a part of a dynamic ecosystem that reflects the seasonal rhythms typical of subarctic hydrology, where spring breakup and snowmelt signal the onset of annual flooding, often complicated by ice jams. Summer brings peaks to glacier-fed rivers, while the river's flow decreases during the deep winter months as it remains covered by ice.
The watershed context
The Iliamna River is nested within the Lake Iliamna watershed, which is one of the largest lake systems in Alaska. This watershed hosts a variety of habitats and plays a crucial role in regional ecology. The flow of the Iliamna River feeds into Lake Iliamna, supporting its diverse aquatic life and playing a significant role in the local fishing economy, which is vital for many communities in the area.
Nearby, the Kvichak River at Igiugig serves as a significant peer to the Iliamna River, showcasing the interconnectedness of the wider hydrological network. In this subarctic climate, the river systems are integral not just for water supply, but also for supporting various forms of wildlife, including salmon, which depend on these waters for spawning.
Why the data matters here
Data from the U.S. Geological Survey (USGS) provides critical insights into the current state of the Iliamna River, including measurements of discharge. Assessing today’s reading in relation to the median for this calendar day over the last 30 years allows for a clearer understanding of current conditions, which can fluctuate significantly with seasonal changes. By comparing it against the historical median, stakeholders such as anglers, cottagers, and local residents can gauge how flow levels today might impact fishing opportunities, water quality, and potential flooding risks in the area. This contextual grounding serves not only to inform immediate users but also enhances the resilience of communities that are closely linked to this vital water resource.
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.
