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 Bow River at Lake Louise

Bow River - A vital waterway through the rugged Rockies.

The Bow River at Lake Louise offers a glimpse into the dynamic hydrology shaped by its mountainous surroundings. Situated in Alberta, this river is integral to the Headwaters Bow watershed, draining roughly 427 square kilometres above the station. This segment of the Bow River contributes to an essential waterway that nourishes both the landscape and the communities downstream.

The watershed context

The Bow River runs through varied terrain, ultimately spanning from the majestic Rockies down through the prairie landscapes of Alberta. Along its journey, this river encounters several peers, including Bow River at Banff, Bow River at Calgary, and Bow River at Cochrane, each contributing to its flow and vitality. The Ever-changing nature of water levels here reflects the influences of mountain snowmelt during the late spring and the summer convective storms that can induce rapid rises.

The Bow River at Lake Louise plays a significant role in sustaining local ecosystems and the water needs of residents and wildlife alike. This stretch of river serves not just as a transportation route for nutrients and sediments but also as a critical water source for both recreational activities and agricultural pursuits downstream.

Why the data matters here

Current measurements from the Bow River at Lake Louise include flow data, critical for understanding seasonal variations and water availability within the region. Daily readings are compared against the median for the calendar day across the station's historical record, which spans 48 years. This context provides crucial insight into the river's performance, helping to distinguish normal fluctuations from significant changes, which can have profound implications for water management, ecology, and flood preparedness.

Monitoring agencies, such as the Water Survey of Canada, provide essential data to inform users about this river's health and stability. Today's elevation, compared to the median for this date, offers a clear snapshot of conditions, essential for local stakeholders, including cottagers, anglers, and farmers who rely on accurate water intelligence.

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.
