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 Pukele Stream near Honolulu, Oahu

Pukele Stream - A dynamic waterway in Oahu's landscape.

Pukele Stream, located near Honolulu on the island of Oahu, reflects the vibrant interplay of tropical island hydrology. This river serves as a key component of the intricate waterways on the island, contributing to Oahu's locally varied hydrological patterns.

The watershed context

Draining roughly 1.2 square miles, Pukele Stream is fed through rainfall-driven runoff typical of the region. The steep, short basins characteristic of Hawaii can lead to sudden and dramatic fluctuations in water levels, with flash floods possible during heavy rain events. This rainfall is often influenced by trade winds and Kona storms, adding to the dynamic character of the local environment.

Pukele Stream has a number of peers in the area, including Heeia Stream and Kalihi Stream, each of which contributes its own flow to the diverse hydrological tapestry of Oahu. The river’s behavior reflects the prevailing weather patterns on the island, which lack a snowmelt season, thereby relying entirely on rainfall for its water supply.

Why the data matters here

The current data for Pukele Stream is crucial for those living or spending time in the area, including local residents, visitors, and emergency planners. Monitoring the stream not only provides insights into its water levels but also serves as a meter for potential flooding events. By assessing stream levels, individuals can stay informed about rapidly changing conditions, which is vital in this rainfall-driven hydrological environment.

Today's reading is compared to the median for today across more than 50 years of historical data provided by the U.S. Geological Survey (USGS). This comparison is important as it gives a more meaningful understanding of current conditions relative to the usual patterns and helps predict potential risks associated with sudden rainfall events.

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.
