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.

About Holland River East at Holland Landing
Holland River East - A vital tributary in the Black River - Lake Simcoe watershed.
The Holland River East flows gracefully through Holland Landing, a key waterway within the Black River - Lake Simcoe watershed in Ontario. This river serves not only as a habitat for diverse aquatic life but also as an important resource for the surrounding communities, connecting cottagers and anglers to the pleasures of the water. Spanning a catchment area of about 177 square kilometres, the Holland River East is fed by various smaller streams, contributing to its role as a vital artery in the region’s hydrology.
The watershed context
Positioned within the broader Black River - Lake Simcoe watershed, the Holland River East plays an essential role in the local hydrological cycle. Neighbouring waterways, such as the Beaver River near Beaverton and the Black River at Baldwin, share this ecological landscape and contribute to the overall health of the region's waterways.
Typically, Ontario experiences a snowmelt-driven seasonal hydrology, meaning that the river sees increased flow during the spring freshet from late April to May. This is followed by a natural decline during the summer months (July through September), as evaporation and reduced inflow begin to take their toll. The environment transitions again as winter approaches, ultimately marked by a steady drop in water levels as ice forms.
Why the data matters here
Water level measurements are essential for understanding the health of the river and the surrounding ecosystem. The Holland River East gauge operates under the jurisdiction of Water Survey of Canada, measuring levels and flows that reflect the overall condition and vitality of the waterway. Today’s reading offers critical insight: it is compared against the median for this calendar day based on nearly 50 years of historical data. This comparison helps to assess fluctuations that may indicate seasonal changes or long-term trends. Understanding these variations assists community members in making informed decisions regarding activities such as fishing and water-based recreation, while also aiding in flood monitoring efforts.
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.
