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 San Josef River below Sharp Creek

San Josef River below Sharp Creek - a lively flow through Northeastern Vancouver Island.

The San Josef River, flowing below Sharp Creek, is a vital watercourse in the Northeastern Vancouver Island region of British Columbia. This area is characterized by its mountain hydrology, where the freshet driven by seasonal snowpack typically peaks from May through July. The river, along with its peer waterways like the Eve River and Nimpkish River, forms an important part of the regional ecosystem, supporting both wildlife and recreational activities for local communities.

The watershed context

Draining roughly 66.4 square kilometres above the station, the San Josef River plays a key role in the local hydrology, contributing to both surface water and groundwater resources. The river’s flows are influenced by the melting snowpack, which, combined with seasonal rains, shapes the water levels throughout the year. Like many rivers in this coastal region, the San Josef River sees significant fluctuations in flow, especially during freshet periods in spring and early summer when the snowmelt and rain combine to swell river levels.

The neighbouring waters in this dynamic watershed include the Keogh River and the Tsitika River, all interlinked within the broader ecosystem of Northeastern Vancouver Island. These connections support a vibrant array of flora and fauna, drawn to the fresh water and rich habitat provided by the river systems.

Why the data matters here

Understanding the flow data for the San Josef River is crucial for managing water resources, predicting possible flooding events, and monitoring ecological health. The gauge measures both levels and discharge, making it a valuable tool for assessing conditions year-round. Today’s reading will be compared to the median for this date over the past 35 years, providing an important indicator of how current water levels align with historical patterns.

According to the Water Survey of Canada, comparing today’s water level against the historical median helps to contextualize current flows in relation to typical conditions. This approach is essential for local landowners and stakeholders relying on accurate data for farming, fishing, and flood preparedness in this vibrant coastal environment.

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.
