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 N. Halawa Str near Honolulu, Oahu
N. Halawa Stream - a vital watercourse on Oahu's eastern shores.
N. Halawa Stream near Honolulu, Oahu, plays a critical role in the local hydrology. This river, with a catchment area of approximately 4 square miles, contributes to the intricate network of waterways that shape this tropical island. Within a short distance, the stream interacts with other notable waterways, such as Heeia Stream and Kalihi Stream, highlighting its position within Oahu's diverse watershed.
The watershed context
The Oahu watershed is defined by its tropical climate, characterized by heavy rainfall that can lead to sudden and powerful flash floods. The area experiences no snowmelt season, unlike many regions in North America, relying instead on trade winds and Kona storms to influence precipitation patterns. This unique environment results in steep, short basins that can rise dramatically in water level within minutes or hours. The N. Halawa Stream is no exception, responding quickly to rainfall events, making it essential for residents and those enjoying outdoor activities in the area to monitor water levels closely.
Why the data matters here
Today’s reading from the N. Halawa Stream gauge provides vital information for understanding water conditions in this fast-changing environment. The data, collected by the U.S. Geological Survey, is compared against the median for this calendar day across the station's 44 years of historical record. By offering insight beyond just the current elevation, this analysis helps locals and visitors alike prepare for rapid changes in water levels, ensuring safety and informed decision-making regarding recreational activities and flood preparedness in this dynamic landscape.
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.
