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.

About Waihi Stream at Honolulu, Oahu
Waihi Stream - A vital flow on Oahu's landscape.
Waihi Stream, located in Honolulu on the island of Oahu, showcases the dynamic hydrology characteristic of tropical island ecosystems. As a rainfall-driven stream, it responds rapidly to precipitation events, embodying the essence of Oahu's weather patterns.
The watershed context
The watershed of Waihi Stream encompasses approximately 1.1 square miles, providing essential drainage for the local area. This small catchment area means that runoff can significantly influence water levels in short periods, particularly during heavy rain or storms. Waihi Stream shares its watershed with various other water bodies, including neighboring Heeia Stream and Honouliuli Stream, further contributing to the interconnected flow and ecological fabric of Oahu.
The tropical climate of Hawaii does not follow a snowmelt season; instead, rainfall events can lead to quick rises in water levels, making monitoring essential for understanding flood risks. The stream is part of a larger network of rivers and streams on the island, which rely on consistent rainfall patterns driving their water levels.
Why the data matters here
Understanding the current water levels in Waihi Stream is crucial for those who engage with the water for various activities, from fishing to collecting rainwater for irrigation. The readings from the U.S. Geological Survey help inform the local community about potential flooding risks in a landscape where flash floods can occur without warning.
As of today, the reading from Waihi Stream indicates water levels compared against the median for this calendar day, based on more than 50 years of historic data. This comparison is particularly useful: it provides context against the usual seasonal behavior of the stream, allowing residents and visitors to make informed decisions about their activities and safety in and around Waihi Stream.
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.
