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 Hanawi Stream near Nahiku, Maui
Hanawi Stream - a vibrant artery of Maui's landscape.
Hanawi Stream flows near Nahiku, Hawaii, within the lush surroundings of the Maui watershed. As part of a network of ephemeral streams on this tropical island, Hanawi offers a dynamic glimpse into the region's richly diverse hydrology, shaped by rapid rainfall and the powerful effects of trade winds.
The watershed context
Draining roughly 3.3 square miles, Hanawi Stream runs through a steep basin typical of Maui's geography, where rainfall can lead to sudden flash floods. This hydrological characteristic is emblematic of tropical island environments, where streams can swell dramatically within minutes during heavy rain events. These rapid changes are driven by localized downpours and are a hallmark of Maui's rainfall patterns.
The stream shares its watershed with several neighboring waterways including Haipuaena Stream, Honokahua Stream, and Honomanu Stream, each contributing to the intricate web of watercourses that characterize the region. Together, these streams play vital roles in the local ecology, supporting a variety of flora and fauna that thrive in this moisture-rich environment.
Why the data matters here
The data collected by the U.S. Geological Survey allows for real-time monitoring of Hanawi Stream, particularly discharge levels, which are crucial for anticipating flooding and informing local residents and visitors alike. Today's reading can be compared to the median for this calendar day over the past 50 years, providing valuable context about current conditions. This historical perspective helps gauge whether today's levels are typical or if unusual weather patterns could point to potential flooding risks. Understanding these patterns empowers decision-making for cottagers, farmers, and all who interact with the waterways on Maui.
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.
