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 Kawela Gulch near Moku, Molokai
Kawela Gulch - A vital waterway on Molokai.
Kawela Gulch flows near Moku on the island of Molokai, Hawaii, channeling rain-driven runoff in a landscape marked by swift changes in elevation and dynamic weather. This river's behavior is shaped by the tropical island hydrology typical of the region, experiencing rapid fluctuations in water level that can occur within minutes to hours.
The watershed context
The Kawela Gulch watershed, part of the larger Molokai watershed, encompasses approximately 5.3 square miles (or about 14 square kilometers) of diverse terrain characterized by steep basins. Rainfall, influenced by trade winds and occasional Kona storms, provides the primary input, leading to flash floods during heavy precipitation. This immediate response to rainfall is an important feature of life on Molokai, where snowmelt is absent, leading to a unique seasonal rhythm.
Surrounding Kawela Gulch are several other waterways, including EF Kawela Gulch, Halawa Stream, and Kamalo Gulch, each contributing to the island's intricate drainage system. These rivers and streams share a similar hydrological pattern, making them key indicators of the island's solid response to weather conditions.
Why the data matters here
Understanding the water conditions at Kawela Gulch is crucial for residents, local agricultural practices, and anyone engaged in outdoor activities in the area. The US Geological Survey (USGS) operates this station and provides real-time data, enhancing flood preparedness and resource management. Today's reading will be compared against the median for this calendar day, offering context that reflects how current water levels align with long-term averages. Given that the USGS has collected data at this site for over 22 years, such comparisons become vital for assessing trends and anticipating potential flooding events.
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.
