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 Waikolu Str blw pipe near Kalaupapa, Molokai
Waikolu Stream - a vital watercourse on Molokai.
The Waikolu Stream flows below a pipe near Kalaupapa, serving as an essential stream within the local hydrology of Molokai. As part of a rainfall-driven landscape, Waikolu Stream exhibits the rapid water level changes characteristic of tropical island environments. Events such as flash floods can occur swiftly in this steep basin, responding dramatically to the heavy rain brought on by trade-wind and Kona storms, creating a unique and dynamic waterway system.
The watershed context
Waikolu Stream is situated within the Molokai watershed, which includes several neighboring watercourses such as EF Kawela Gulch, Halawa Stream, and Kamalo Gulch. This small river drains an area of approximately 3.8 square miles, channeling rainwater from the surrounding hills down to the coastal regions. With no snowmelt to contribute to flow patterns, the stream's behavior is heavily reliant on the rainfall distribution, which can result in significant fluctuations over short periods.
While the watershed supports various flora and fauna, the specific ecological features are not detailed in the current data. Nevertheless, understanding the hydrology of this area is essential to comprehend the natural cycles in play and how water behaves in this environment.
Why the data matters here
Today's reading from the Waikolu Stream is a crucial indicator of the current river conditions. The gauge operated by the U.S. Geological Survey (USGS) allows for the comparison of today's stream level to the historical median for this day over the past 50 years. This benchmarking is vital; measuring the current conditions against established historical norms helps gauge water levels' significance and context rather than simply relying on elevation data alone. Through this understanding, local residents, farmers, and flood-watchers can better assess the risks and opportunities presented by the waters of Waikolu Stream.
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.
