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 Indian River at Pembroke

Indian River - A key tributary in the Central Ottawa - Bonnechere watershed.

The Indian River at Pembroke serves as a vital waterway within the Central Ottawa - Bonnechere watershed in Ontario. This river, approximately 465 square kilometres of its drainage area flows above the station, contributes to the regional hydrology, especially notable during the snowmelt-driven seasonal cycle.

The watershed context

The waters of the Indian River play an essential role in managing the water flow in the Central Ottawa - Bonnechere watershed. This region experiences significant seasonal variations, with a distinct spring freshet occurring from late April to May, which is largely attributed to snowmelt. The summer months, from July through September, typically see a natural drawdown of water levels as evaporation processes take hold alongside reduced inflows. As winter approaches, the Indian River's flow declines with the onset of ice formation.

Why the data matters here

Understanding the water levels recorded at the Indian River is crucial for various stakeholders, including local cottagers and businesses. The current reading from the Water Survey of Canada helps to gauge the health and behaviour of the river throughout the seasons. Today’s measurement is compared against the median for this calendar day based on the historical record spanning 17 years, providing essential context to evaluate conditions. This method of comparison assures that users focus not just on raw elevation, but on fluctuations that inform about both seasonal trends and immediate changes to the waterway's health.

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.
