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

About St. Francis River at Outlet of Glasier Lake

St. Francis River - A vital conduit in the Upper Saint John watershed.

The St. Francis River flows from the outlet of Glasier Lake, carving through the rugged landscape of New Brunswick. This river is a significant part of the Upper Saint John - St. Francis watershed, which encompasses a diverse array of ecological features and water bodies. With a catchment area of approximately 1,350 square kilometres above the station, it plays a crucial role in managing and distributing the region's water resources.

The watershed context

This river is connected to notable peers such as the Saint John River at Edmundston and the St. John River at Dickey, Maine. Each of these waterways contributes to the hydrology of the larger Saint John River system, which is integral to the ecology and human activities in the region. The seasonal rhythm of New Brunswick's Atlantic hydrology reveals a pattern characterized by a spring snowmelt freshet, posing a risk for ice jams on the major rivers. This seasonal fluctuation affects water levels significantly, with the potential for fall rain floods and the effects of winter ice cover.

Why the data matters here

Understanding the water levels and flow at the St. Francis River is essential for various stakeholders, including cottagers, anglers, and farmers. Today's reading is evaluated against the historical median for this date, providing context to its current elevation and flow conditions. The Water Survey of Canada operates this gauge, and the current level can indicate whether conditions are normal, high, or low compared to typical levels over the past 74 years of recorded data. This knowledge empowers local communities to make informed decisions on water use and engage with the landscapes around them responsibly.

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.
