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 Mississippi River at Appleton
Mississippi River at Appleton - a key flow point in the Ottawa-Mississippi watershed.
The Mississippi River at Appleton is a significant segment of the expansive Central Ottawa - Mississippi watershed in Ontario. This river provides vital water flow and condition data for local users, including agriculture, recreation, and environmental monitoring. The river, along with its peers such as Bennett Lake, Dalhousie Lake, and the Ottawa River at Britannia, forms an integral part of the regional hydrology.
The watershed context
Draining roughly 2,930 square kilometres above the station, the Mississippi River at Appleton is a pivotal area for understanding the seasonal rhythms typical of the region. The hydrology here is predominantly driven by snowmelt, with a spring freshet occurring from late April to May, which contributes significantly to water levels. As summer approaches, natural drawdown occurs from July to September due to evaporation and reduced inflow. This seasonal pattern is essential for local ecosystems and water management alike, highlighting the dynamic nature of water flow in this area.
Why the data matters here
The operating agency for water data at this station is the Water Survey of Canada. Today's water level reading at the Mississippi River at Appleton can be compared to the historical median for this calendar day over the past 50 years, providing context and understanding beyond mere elevation figures. This comparison allows cottagers, farmers, and anglers to gauge current conditions and make informed decisions about their activities, whether itupon fishing, irrigation, or flood management.
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.
