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 Waihee River above Waihee Dtch intk near Waihee, Maui
Waihee River - A dynamic watercourse driven by rainfall.
The Waihee River flows through an engaging landscape on the island of Maui, where its waters respond rapidly to rainfall events. This river, situated above the Waihee Ditch intake, is part of a network of streams that harness the unique hydrological patterns of Hawaii. The watershed contributes to the island's diverse ecosystems and provides critical water resources for both natural habitats and human needs.
The watershed context
Draining an area of approximately 4.3 square miles, the Waihee River captures precipitation from Maui's rugged terrain. The watershed is characterized by steep gradients and short basins, leading to quick rises in water levels during heavy rainfall. This tropical island hydrology means that residents and visitors alike must be prepared for flash flood conditions that can develop in mere minutes, especially during trade-wind and Kona storm systems. The nearby Haipuaena Stream and other local peers such as Honokahua Stream and Honomanu Stream reflect the interconnectedness of these waterways, all of which share a similar susceptibility to sudden water level fluctuations.
Why the data matters here
Understanding the water levels of the Waihee River is vital for local residents and stakeholders, particularly given the potential for rapid flooding. Current data provided by the U.S. Geological Survey (USGS) not only highlights the live measurements of the river but offers a critical comparison against historical median levels for the calendar day. This context allows those who depend on the river’s resources to assess current conditions against a reliable standard.
Today’s reading, measured against the historical median across 43 years of records, accurately depicts how current water levels stand relative to the past. Such comparisons are essential for flood preparedness and water management strategies in this responsive environment.
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.
