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 Talkeetna R near Talkeetna AK

Talkeetna River - A vital link in Alaska's hydrology.

The Talkeetna River, located near the community of Talkeetna, Alaska, is a significant and dynamic waterway within the subarctic hydrology context of the region. This river serves as a vital resource for the surrounding ecosystems and communities, shaped by the seasonal patterns characteristic of Alaskan water bodies. The river is part of a larger watershed, with an upstream drainage area of approximately 2,010 square miles.

The watershed context

The Talkeetna River benefits from runoff driven by spring breakup and snowmelt, which significantly influences its flow patterns. During the spring months, ice jams can form, contributing to annual flood events, while glacier-fed tributaries reach their peaks later in the summer, contributing to increases in water levels. In the winter, the river experiences significantly lower flows under a cover of ice, as is typical in subarctic environments. This seasonal rhythm dictates much of the ecological and hydrological characteristics of the river.

Why the data matters here

Data collected from the USGS station on the Talkeetna River provides crucial insights into its flow dynamics, contributing to a deeper understanding of water resource management, ecological health, and community planning. Today's reading helps reveal how the river stands compared to its historical record, providing a valuable context for monitoring trends and understanding potential impacts from climate variability.

As of today, the river’s elevation reading is measured against the median for this calendar day over the past 50 years. This comparison, supplied by the United States Geological Survey, offers a more meaningful perspective than raw elevation numbers alone, allowing for better assessments of the river's status and trends.

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.
