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 Waiaha Stream at Holualoa
Waiaha Stream - A dynamic flow in Hawaii's lush landscape.
Waiaha Stream flows through the heart of Holualoa, a vibrant area characterized by its steep terrain and rich biodiversity. With a drainage area of roughly 10.9 square miles, this stream is a critical water source impacted by the distinctive tropical island hydrology of Hawaii. Rainfall drives the flow patterns here, leading to rapid rises in water levels during rain events, particularly influenced by the trade winds and Kona storms that can transform the landscape in mere minutes to hours.
The watershed context
Situated within the Hawaii watershed, Waiaha Stream is connected to several neighboring streams such as Alakahi Stream and Hakalau Stream. This network contributes to the overall hydrological dynamics of the region, creating a complex web of water flows that supports the lush vegetation and diverse ecosystems found here. Flash flooding can occur when rainfall is heavy, demonstrating how quickly conditions can change in these steep basins.
The wet environment of Holualoa fosters unique ecological communities adapted to thrive in such dynamic conditions. The interplay between the land and water systems here is intricate, influencing everything from local agriculture to wildlife habitats.
Why the data matters here
Understanding the current flow metrics of Waiaha Stream is essential for residents, farmers, and anyone engaging with the land and water around Holualoa. The United States Geological Survey (USGS) provides real-time data to help monitor water levels, which is crucial during periods of heavy rainfall. Today’s reading should be compared against the historical median for this date across 24 years of records. This comparison offers a clearer picture of current conditions relative to typical flow patterns, enhancing the understanding of the stream's behaviour and informing necessary precautions against potential flash floods.
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.
