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 Waikapu Str US of S Waikapu Dt intake, Maui
Waikapu Stream - A dynamic waterway of Maui.
Waikapu Stream, located on the vibrant island of Maui, is a river that captures the power and unpredictability of tropical rainfall. This stretch of water is influenced heavily by the region's unique hydrology, receiving intense rainfall that can lead to rapid downstream surges. With a catchment area of roughly 1.8 square miles, Waikapu Stream is shaped by the landscape and weather patterns of Hawaii, where flash floods can arise swiftly due to steep basins driving rainwater into the stream.
Why the data matters here
The United States Geological Survey (USGS) monitors the stream, providing crucial data on its discharge. Understanding the flow and elevation readings from the stream is invaluable for local residents and resource management. Given the potential for sudden flooding during rainfall, real-time data facilitates informed decision-making for safety and ecological management.
With three years of recorded data, today's reading allows for comparison against the median for this day, providing context that raw elevation alone cannot yield. This comparative insight is essential for accurately assessing current conditions and anticipating changes that could affect activities in the surrounding areas, such as agriculture and recreation.
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.
