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 Twenty Mile Creek above Smithville
Twenty Mile Creek - a vital tributary in the Niagara watershed.
Twenty Mile Creek flows above Smithville, carving its path through a landscape shaped by the rich water legacy of the Niagara region. This river serves as a crucial waterway, contributing to the complex hydrology of its larger watershed and supporting a diverse range of ecological processes.
The watershed context
Nestled within the Niagara watershed, Twenty Mile Creek drains roughly 166 square kilometres before it joins with the broader network feeding into the renowned Niagara River. This creek shares its neighbourhood with peers like Twelve Mile Creek near Power Glen and Twenty Mile Creek at Balls Falls, each contributing to the shared ecology and hydrology of the region. During spring, the flow in Twenty Mile Creek typically swells due to snowmelt, leading to the spring freshet often observed in late April through May. This period of increased flow is essential for transporting nutrients and supporting aquatic habitats.
As summer approaches, the natural drawdown occurs, as expected from the seasonal patterns in Ontario. Water levels may recede from their spring highs due to evaporation and reduced inflow, a process that influences the health and dynamics of the creek’s ecosystem. The initial stages of winter introduce a decline in flow as ice begins to form, marking the transition into a new seasonal cycle.
Why the data matters here
Understanding the water levels and flow characteristics of Twenty Mile Creek is vital for local stakeholders, including cottagers, farmers, and anglers. Recent readings from the station, which reports both elevation and discharge, provide a snapshot of current conditions. Today's reading can be compared to the median for this calendar day across the station’s historical record spanning 39 years. This comparison offers a crucial context for assessing how current levels may relate to the creek's typical behaviour, especially during changing seasons. Consistent monitoring by the Water Survey of Canada (WSC) ensures that residents and businesses can access relevant data to better inform their activities and decision-making processes as they engage with this important aquatic resource.
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.
