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.

The flood of record that was overtaken

For five years, spring 2019 was the mark every Lake Muskoka decision answered to. In April 2026 the lake went two centimeters higher - and the official books have not caught up yet.

About Mackay Creek at Montroyal Boulevard

Mackay Creek - A vibrant mountain stream in British Columbia.

Nestled in the picturesque terrain of British Columbia, Mackay Creek flows gracefully at Montroyal Boulevard. This stream is part of the Strait of Georgia - Squamish watershed, a region characterized by its diverse hydrological features shaped by the nearby mountains. The creek is surrounded by an ecosystem that thrives off the fresh water that emerges from the snowmelt and rain, making it an essential habitat for local wildlife and a valuable resource for the community that enjoys it.

The watershed context

Mackay Creek drains approximately 2.9 square kilometres, showcasing the region's reliance on mountain hydrology. Being a smaller creek, it is influenced by the seasonal rhythms typical of British Columbia, which experiences freshets driven primarily by melting snowpack. In this area, water levels generally peak between May and July, aligning with the late spring thaw. As the snow recedes and temperatures rise, the creek swells, feeding into the wider rivers and channels eventually leading to the Strait of Georgia.

Nearby, some significant peers in the watershed include the Capilano and Cheakamus rivers — both known for their swift currents and natural beauty. These larger water bodies share similar hydrological patterns, influenced by rainfall and snowmelt. The interplay of these streams contributes to the overall health of the local ecosystem and recreational opportunities for those who explore the area.

Why the data matters here

Understanding the current water levels at Mackay Creek is vital for various stakeholders, including local anglers, residents, and environmentalists. Today's reading from the Water Survey of Canada gives an essential snapshot of the hydrological conditions of the creek. By comparing the level to the median for this calendar day over a historical record of 49 years, one can ascertain whether the creek is running higher or lower than typical for this time of year. This insight allows community members and water-management agencies to monitor potential flooding risks or plan for water usage during drier periods.

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.
