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.

Why the Assiniboine floods every spring

Inside the freshet cycle that puts Manitoba shorelines at risk each year - and why 2026 broke the script.

Why Central and South Texas rivers go from gravel beds to fifty-year records in an afternoon - including July 2026 on the Nueces.

About Rocky River near Colinet

Rocky River - a dynamic waterway flowing near Colinet.

The Rocky River courses gracefully through the landscape near Colinet, Newfoundland and Labrador. This river is an integral component of the Eastern Placentia and Western St. Mary's Bays watershed, traversing an area of 296 square kilometers that captures the diverse hydrology of the region. Known for its seasonal changes, the Rocky River is influenced by the Atlantic hydrology, which features a spring snowmelt freshet and fall rain floods that are moderated by the surrounding lakes and bogs.

The watershed context

As part of the larger Eastern Placentia and Western St. Mary’s Bays watershed, the Rocky River shares its vicinity with several other watercourses, including the Little Salmonier River, Northeast River, and various segments of Rattling Brook. Together, these waterways form a rich ecosystem that helps manage the rainfall and runoff characteristic of the region, particularly during the more turbulent seasonal shifts. The interaction between land and water here is dynamic, where the surrounding peatlands and forests contribute to the river's flow and the overall health of the watershed.

Why the data matters here

Current measurements of the Rocky River are essential for understanding its flow patterns and variations throughout the year. The station located at this river provides valuable discharge data, allowing for effective monitoring and management of water resources in the area. Today’s reading from the Water Survey of Canada (WSC) compared against the median for this calendar day across nearly 50 years of historical data grants insight into current conditions. Understanding how today’s levels align with historical trends helps local cottagers, anglers, and farmers adapt to the immediate hydrological situation and plan accordingly for the seasons ahead.

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.
