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.

Why the Assiniboine floods every spring

Inside the freshet cycle that puts Manitoba shorelines at risk each year - and why 2026 broke the script.

Flash Flood Alley: how Texas rivers rise in hours

Why Central and South Texas rivers go from gravel beds to fifty-year records in an afternoon - including July 2026 on the Nueces.

About Saint John River at Oak Point

Saint John River - A vital watercourse in New Brunswick.

The Saint John River at Oak Point is a significant stretch of water within New Brunswick's evolving landscape. Draining roughly 51,900 square kilometres, this river's flow influences the local ecosystem and the communities that rely on it.

The watershed context

This section of the Saint John River plays a crucial role in the Lower Saint John - Kennebecasis watershed. With neighbouring rivers like the Canaan River and the Kennebecasis River, the Saint John offers connectivity and sustenance to the surrounding habitats and human activity. The watershed reflects Atlantic hydrology patterns, with a spring snowmelt freshet presenting unique conditions, particularly at this time of year, alongside the risks of ice jams in the colder months. Each season brings varied hydrological features, such as potential fall rain floods and the delicate balance of winter ice cover.

Why the data matters here

Today's reading from the Saint John River at Oak Point is significant compared to the historical median for this date, recorded over the past 103 years. This context allows for understanding the river's current state beyond just its elevation; tracking the data helps gauge seasonal shifts and long-term trends. Water Survey of Canada monitors these levels to ensure awareness of changes in the environment that could impact both natural and human systems in the area.

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.
