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 Puntledge River below Diversion

Puntledge River - A vital flow on Vancouver Island.

The Puntledge River below Diversion presents a dynamic snapshot of water management and ecology on South Central Vancouver Island. This section of the river, which is part of a larger system influenced by the region's mountain hydrology, serves as an essential resource for local ecosystems and communities alike.

The watershed context

Draining roughly 472 square kilometres above the station, the Puntledge River captures the runoff from the surrounding mountains, particularly during the freshet period driven by melting snowpack. The peak flow typically occurs from May through July, as warmer temperatures lead to rapid snowmelt and increased river volume. This seasonal rhythm creates a lively waterway, contributing to the overall health of the watershed and offering a variety of recreational opportunities for residents and visitors.

The river finds itself accompanied by notable peers in the region, including Ash River, Browns River, and Englishman River. These rivers and creeks add to the hydrological complexity of the area, creating a network that supports a range of habitats. As the rivers flow towards their respective mouths and join the coastal currents, they underscore the interconnectivity of Vancouver Island's waterways.

Why the data matters here

Current measurements from the Water Survey of Canada at the Puntledge River below Diversion provide crucial information about its flow conditions. Regular monitoring allows for a comparative analysis against historical data, revealing trends and helping to ensure sustainable water usage. Today's reading contributes to this understanding, providing insight into the river's performance relative to the median for this specific calendar day across more than 32 years of records. This approach to data not only enriches our awareness of river conditions but also aids in predicting forthcoming changes that could impact the surrounding environment and communities.

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.
