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.

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 Neebing River near Thunder Bay

Neebing River - A dynamic waterway reflecting seasonal patterns.

The Neebing River near Thunder Bay is a vital part of the Dog watershed in Ontario, characterized by its seasonal flow patterns. This river is integral to the local ecosystem and serves as an important source of water for surrounding communities, wildlife, and recreational activities. It drains an area of roughly 208 square kilometres above the monitoring station.

The watershed context

The Dog watershed, where the Neebing River flows, is shaped by the seasonal rhythm of Ontario’s hydrology. Each year brings a cycle of change dictated by snowmelt, which feeds the river through the spring freshet in late April and May. Following this period of increased flow, the river experiences a natural drawdown during the summer months from July to September, when evaporation and reduced inflow come into play. As winter approaches, the river's diurnal rhythm slows, leading to a distinct decline as ice forms.

The Neebing River connects with peers such as the Whitefish River at Nolalu, forming a network of tributaries that support the local ecology. The river’s role in this watershed highlights its importance not only to local fish and wildlife but also to those who engage in fishing, boating, and other outdoor activities along its banks.

Why the data matters here

Today's reading for the Neebing River provides valuable insights into its current flow and water levels, crucial for understanding conditions for various uses, including flood management and ecosystem health. When evaluating this reading, it is useful to compare it to the median for this calendar day across the station's historical record—now spanning more than 50 years, as provided by the Water Survey of Canada. This comparison helps to identify trends and anomalies in the river's behavior over time, allowing for better-informed decisions by cottagers, anglers, and local authorities. Understanding the river’s flow dynamics is essential for preserving the integrity of the entire watershed.

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.
