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 Honokahua Stream at Honoapiilani Highway, Maui
Honokahua Stream - A dynamic watercourse shaped by tropical rainfall.
Honokahua Stream flows alongside the Honoapiilani Highway on the lush island of Maui, Hawaii. In this region, the hydrology is distinctly tropical, characterized by rapid rises in water levels due to intense rainfall events. The surrounding landscape, influenced by trade winds and occasional Kona storms, often leads to sudden flash floods, transforming the stream dramatically within a short period.
Why the data matters here
Water data from the Honokahua Stream is essential for understanding the immediate hydrological patterns influenced by Maui's tropical climate. This stream does not have a defined drainage area recorded, yet it is part of a network of tributaries sharing the island’s watershed. Nearby streams, such as Haipuaena Stream and Hanawi Stream, echo similar rainfall-driven behaviors, highlighting the interconnectivity of these waterways under tropical storm conditions.
For anyone monitoring local conditions, the stream’s data offers vital insights. The U.S. Geological Survey (USGS) collects and provides these measurements, which help inform community preparedness for flash flooding events—an everyday concern on the island. Being aware of current water levels, particularly in relation to historic highs, allows residents and visitors alike to stay safe when engaging with the landscape.
Today’s reading for Honokahua Stream has been taken into account against the median level for this calendar day across the past year, reflecting the stream's recent trends in the context of the seasonal rainfall patterns that define Maui’s weather. This approach offers a more meaningful understanding of current conditions compared to absolute elevations alone.
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.
