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 Coquitlam Lake
Coquitlam Lake - A vital reservoir in the Lower Fraser - Coast region.
Coquitlam Lake serves as an essential reservoir, contributing to both the ecological health of the Lower Fraser - Coast watershed and the water supply for the surrounding communities. The lake is located in British Columbia and is sustained by the mountainous hydrology characteristic of this region. With its catchment covering approximately 187 square kilometres, Coquitlam Lake plays a significant role within its watershed, which is known for its dynamic seasonal patterns driven by snowmelt and rainfall.
The watershed context
In the context of the Lower Fraser - Coast watershed, Coquitlam Lake is surrounded by a diverse network of waterways. Notable peers include the Alouette River and various segments of the Chilliwack River, which together create a vibrant aquatic ecosystem supporting both wildlife and recreational activities. Due to the influence of mountain hydrology, the lake experiences a freshet heightened by snowpack, generally peaking between May and July. This seasonal rhythm is crucial as it not only replenishes the lake but also supports the ecological systems downstream in the river networks.
Why the data matters here
Understanding the lake's water level is vital for anticipating ecological and supply-related changes that may arise from the seasonal fluctuations. Regular data collection at the Coquitlam Lake Forebay station reflects current water levels and is instrumental in ensuring the health of the lake and surrounding ecosystems.
Today's reading from the Coquitlam Lake Forebay station, operated by the appropriate water management authorities, is essential for contextualizing the water level against historical data. Comparing this reading to the median for the calendar day across over 41 years of records provides insights into current conditions, offering a valuable perspective that raw elevation figures alone cannot convey.
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.
