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.

About Thompson River at Kamloops

Thompson River - A vital waterway in British Columbia.

The Thompson River at Kamloops represents a significant stretch of this dynamic river system in British Columbia. Known for its diverse hydrology, the Thompson River is a critical resource for both the surrounding environment and local communities. With a substantial drainage area of approximately 38,200 square kilometers, this river is fed by various tributaries, showcasing the complexity of its watershed.

The watershed context

The Thompson watershed is known for its mountain hydrology, influenced by seasonal rhythms marked primarily by snowmelt. Typically, freshet driven by accumulated snowpack leads to peak flows from May through July, creating an active and vibrant river landscape during the spring and early summer months. The river flows through the city of Kamloops, where it serves as an essential water supply and recreational resource for residents and visitors alike. Nearby waterways such as Arrowstone Creek, the Bonaparte River, and Dairy Creek bolster the river's capacity and ecological richness.

Why the data matters here

Understanding the flow data from the Thompson River is crucial for various stakeholders, including anglers, farmers, and flood-watchers. Today's reading provides invaluable insight, as it can be compared to historical flow data recorded over the last 49 years. Such comparisons help gauge the river's current performance against the median for this calendar day, giving context that raw elevation data alone cannot provide.

The Water Survey of Canada monitors and publishes flow data, allowing users to make informed decisions based on real-time updates. Whether you're planning a day of fishing, assessing agricultural water needs, or monitoring for flood risks, awareness of the river's current conditions is essential for effective management and enjoyment of this critical 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.
