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 Rideau River below Merrickville
Rideau River below Merrickville - A vital stretch of water flowing through the Rideau watershed.
The Rideau River below Merrickville offers an interesting glimpse into the dynamic interactions of water, landscape, and seasonality within the Rideau watershed. As part of a larger system that influences both the local ecology and human activities, this section of the river joins various peers, including Kemptville Creek, Rideau River below Manotick, and others, enriching the waterway's connectivity and health.
The watershed context
Spanning an expansive drainage area of roughly 1980 square kilometers, the Rideau River below Merrickville is influenced by the broader characteristics of the Rideau watershed. This area is shaped by its seasonal rhythms, particularly snowmelt-driven hydrology, which results in a seasonal freshet typically occurring from late April to May. The melting snow feeds the river, increasing flow rates and invigorating the ecology downstream.
During the summer months from July to September, the river experiences natural drawdown as evaporation and reduced inflows take hold, resulting in lower water levels. A decline also occurs in early winter as ice begins to form. Each seasonal transition brings changes that affect the surrounding ecosystem, recreational opportunities, and the health of local fisheries.
Why the data matters here
The gauge on the Rideau River below Merrickville is crucial for monitoring water levels and discharge, making it a valuable tool for anyone engaging with the river, from local farmers to recreational enthusiasts. As of today, the reading from the Water Survey of Canada indicates a level that provides context against the median for this date over 46 years of recorded data. Comparing today's reading to the historical median allows us to understand how current conditions stack up against established patterns, better informing water management efforts and flood monitoring in this important region.
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.
