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.

Gull Lake Water Level

Live lake level, flow, historical records and forecast for Gull Lake in 40,41-28-W4; 41,42-1-W5, AB, Canada, built from official government gauge data.

About Gull Lake

Gull Lake - a central hub for outdoor recreation.

Gull Lake is located in Alberta, within the Upper Red Deer - Blindman watershed. This lake is known for its vibrant recreational opportunities, attracting visitors for fishing, boating, and leisurely days on the water. With a drainage area of approximately 303 square kilometres, it captures runoff from the surrounding landscape and contributes to local hydrology.

The watershed context

Gull Lake is flanked by the Red Deer River and Sylvan Lake, both of which play roles in the regional hydrology. The lake's ecosystem thrives within a landscape shaped by the contrasting foothills and prairie regions of Alberta. Seasonal changes influence water levels significantly; late spring peaks often occur due to mountain snowmelt, while summer convective storms can lead to sharp increases in water levels. These natural cycles create a dynamic and ever-changing environment for both wildlife and outdoor enthusiasts alike.

Why the data matters here

Current hydrological data for Gull Lake comes from the station at Rv Heaven Marina. Comparing the lake's water level to the median for this calendar day gives valuable insights into its fluctuations over the past 13 years of recordkeeping. Understanding these changes is essential for stakeholders such as anglers, cottagers, and community planners who rely on accurate hydrological data to inform their activities around the lake. The Water Survey of Canada provides these measurements, allowing for informed decisions and better management of the natural resources in this vibrant area.

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.
