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.

Water Stories

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 Slesse Creek near Vedder Crossing

Slesse Creek - A tranquil tributary of the Lower Fraser.

Nestled near Vedder Crossing in British Columbia, Slesse Creek flows as a vital watercourse within the Lower Fraser - Coast watershed. This creek serves as an important tributary to the broader Fraser River system, connecting with multiple local peers like the Chilliwack River and Alouette River. With a drainage area of approximately 160 square kilometers upstream of the monitoring station, Slesse Creek plays a critical role in the local hydrology, particularly influenced by the region’s unique mountain dynamics.

The watershed context

The Lower Fraser - Coast watershed, characterized by its diverse hydrological patterns, experiences significant seasonal variability. The region typically sees a freshet from snowmelt snowpack, with flows often peaking between May and July. The influence of glacial feeds also helps sustain flows throughout the summer months, resulting in a consistent supply of water to the diverse ecosystems supported by these waterways. As part of this complex system, Slesse Creek contributes its share of water, serving local flora and fauna and those who use the water for recreation and livelihood.

Nearby streams and rivers such as the Chilliwack River and Coquitlam River create a rich aquatic network, intimately tied to the surrounding landscapes. The flow dynamics of Slesse Creek not only benefit the immediate environment but also have implications for the larger hydrological patterns downstream.

Why the data matters here

Monitoring of Slesse Creek is essential for understanding water level fluctuations and providing data crucial for management and conservation efforts. The station recording this data, Slesse Creek near Vedder Crossing, has been operational for over 49 years. This historical perspective allows comparison of current water levels to the median for this calendar day, offering valuable insights into trends and changes over time.

As of today, the water level at Slesse Creek is measured at a particular elevation against the historical median recorded by the Water Survey of Canada. This method of comparison helps gauge whether current conditions are unusually high or low, providing context that raw figures alone cannot deliver. Having this data available is vital for anyone relying on Slesse Creek’s waters, from local landowners to recreational users.

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.
