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.

Water Stories

The flood of record that was overtaken

For five years, spring 2019 was the mark every Lake Muskoka decision answered to. In April 2026 the lake went two centimeters higher - and the official books have not caught up yet.

Trout River at Kilometre 783.7 Alaska Highway Water Level

Live river level, flow, historical records and forecast for Trout River at Kilometre 783.7 Alaska Highway in Canada, BC, Canada, built from official government gauge data.

About Trout River at Kilometre 783.7 Alaska Highway

Trout River - A vital waterway of the Central Liard - Toad watershed.

Trout River flows through the scenic landscapes of British Columbia, providing critical ecological and hydrological functions. This river, located at Kilometre 783.7 along the Alaska Highway, represents a significant part of the Central Liard - Toad watershed, draining roughly 1,210 square kilometres above the station. Adjacent rivers like the Liard River, Smith River, and Teeter Creek enhance the hydrology of the region, creating a complex network of waterways connected to the surrounding landscape.

The watershed context

The Central Liard - Toad watershed showcases the vibrant interplay of mountain hydrology typical of British Columbia. The region experiences a freshet largely driven by snowpack, which often peaks between May and July, resulting in significant runoff that nourishes rivers and streams during warmer months. As snow melts in the mountains, the Trout River swells, reflecting this seasonal rhythm that supports both aquatic habitats and surrounding ecosystems.

The Trout River is positioned within a dynamic environment, where the glacial-fed waterways typically remain high through the summer, vital to sustaining wildlife and plant life during the drier months. This connectivity to neighboring water bodies is essential for biodiversity and ecological resilience, making this river a critical resource for the region.

Why the data matters here

Monitoring the Trout River provides valuable insights into the health of the watershed and its response to seasonal changes. As of today, conditions observed at this river gauge can be better understood by comparing today's reading against the median for this calendar day over nearly five decades of historical data gathered by Water Survey of Canada. This approach offers a nuanced perspective, indicating how current water levels relate to long-term averages, which is particularly important for understanding seasonal trends, potential flooding, and water availability for local ecosystems. Knowing where the river stands in relation to its median helps manage and protect 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.
