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 Zeballos River near Zeballos

Zeballos River - A vital freshwater source on Northwestern Vancouver Island.

The Zeballos River flows near the small community of Zeballos on the rugged Northwestern Vancouver Island. This river is a key component of the regional hydrology, influenced by the mountainous terrain that characterizes the area. It serves as an essential drainage channel, capturing runoff from its catchment area of approximately 181 square kilometres. Known for its dynamic flow patterns, the river experiences changes that reflect the typical seasonal rhythms prevalent in British Columbia's coastal regions.

The watershed context

The Zeballos River is part of the larger Northwestern Vancouver Island watershed, which showcases the diverse hydrological features of the region. With mountain-fed dynamics, the river typically sees freshet brought on by melting snow, with flow often peaking from May through July. This seasonal cycle is vital for sustaining the ecosystems and local communities that rely on its waters. During the summer, flows may decline due to natural evaporation and reduced inflow, a common pattern in many coastal systems.

Why the data matters here

Monitoring the Zeballos River is essential for understanding its health and resilience. The Water Survey of Canada operates the station measuring water levels and flow rates, providing vital data for locals, cottagers, and environmental enthusiasts. Today's reading of the Zeballos River is compared against the median for this calendar day over 49 years of historical data, offering a more meaningful perspective than a single raw elevation. Understanding how current levels stack up against historical averages helps gauge performance under variable conditions, shaping our awareness of this river's contributions to the local ecosystem.

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.
