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 Mimico Creek at Islington
Mimico Creek - A vibrant urban waterway.
Mimico Creek flows gracefully through the heart of southern Ontario, a vital artery amid urban settings. Located at Islington, this river meanders through the Humber - Don watershed, showcasing the intricate relationship between nature and the city. A catchment area of roughly 68 square kilometres drains into this stretch of the creek, highlighting its role as an important freshwater resource within the larger ecosystem.
The watershed context
The Humber - Don watershed is a dynamic landscape, encompassing a variety of habitats and water bodies, including notable peers like Black Creek, the Don River's East and West branches, and Etobicoke Creek. Together, these tributaries contribute to the intricate hydrological network that supports local wildlife and maintains the natural balance within urban environments. Mimico Creek itself plays a crucial role in this network, facilitating drainage and providing a habitat for diverse flora and fauna.
This section of Mimico Creek experiences snowmelt-driven hydrology, with peak flows typically occurring during the spring freshet in late April and May. As temperatures rise and snowpack diminishes, increased water levels can be observed, signaling a seasonal transformation. During summer, natural drawdown occurs as flows stabilize and water levels gradually decline leading into fall. Early winter sees another decrease as ice starts to form, completing the creek’s seasonal rhythm.
Why the data matters here
Understanding the hydrology of Mimico Creek at Islington is essential for managing water resources effectively. The station not only measures water levels but also gauging discharge provides valuable insights into the creek's flow patterns and health.
Currently, the water level is monitored against historical data from the Water Survey of Canada, allowing for meaningful comparisons to the median for this calendar day. This metric is particularly valuable as it provides context for today’s conditions, improving our understanding of both current and upcoming water behavior. With 49 years of record data, this monitoring plays a crucial role in flood management, ecology studies, and overall water quality assessments.
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.
