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 Oyster River below Woodhus Creek

Oyster River below Woodhus Creek - A vital link in the East Central Vancouver Island watershed.

Nestled in the robust mountainous terrain of East Central Vancouver Island, the Oyster River below Woodhus Creek plays a significant role in the region's diverse hydrology. With a drainage area of approximately 297 square kilometres feeding into this river, it is an important conduit for freshwater as it flows through a landscape shaped by both snowmelt and seasonal precipitation patterns characteristic of British Columbia's coastal climate.

The watershed context

The East Central Vancouver Island watershed encompasses an array of waterways, all interconnected through a network that includes notable peers such as Buttle Lake and Campbell River. These connections create a dynamic ecosystem, where various tributaries, including the Little Oyster River and Quinsam River, contribute their own distinct flows to the Oyster River. The freshet, driven by melting snowpack, is a hallmark of this region, typically peaking from May to July. This pattern not only influences water levels but also supports the local ecological systems.

Why the data matters here

Staying informed about the water levels and flow rates is crucial for those who depend on the Oyster River, whether for recreational activities or ecological stewardship. This gauge measures both the level of the water and its discharge, providing important context for understanding the river's health and the surrounding ecosystem.

Today's reading from the Oyster River below Woodhus Creek can be compared to the median for this calendar day based on nearly 49 years of collected data from the site. This comparison offers a useful perspective; knowing how current water levels position against historical norms is essential for effectively monitoring the river's trends over time. The operating agency for this data is the Water Survey of Canada, providing reliable insights into the changing dynamics of this vital waterway.

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.
