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 Punaluu Str above Punaluu Ditch Intake, Oahu
Punaluu Stream - A rainfall-driven waterway on Oahu.
Punaluu Stream flows above the Punaluu Ditch Intake on the island of Oahu, providing a vital link in the complex web of the island’s hydrology. This stream, measuring just 2.8 square miles in its catchment area, is characteristic of Oahu's steep, rainfall-driven basins. Here, the landscape rises rapidly, allowing for quick responses to the island's variable weather patterns, particularly during trade-wind and Kona storm events.
The watershed context
The Punaluu Stream is part of the larger Oahu watershed and plays an essential role in the hydrological dynamics of the region. Surrounded by steep terrain, this area is prone to flash floods as the rainfall can cause the water level to rise significantly within minutes to hours. The Punaluu Stream connects with numerous local water bodies, including its peers such as Heeia Stream and Kahaluu Stream, all of which share similar responses to the tropical rainfall patterns that dominate Hawaii.
While Oahu does not experience a snowmelt season like many other parts of the United States, its precipitation patterns are unique and impactful. Rainfall is often intense, and the flash flood risk necessitates vigilance among those living and working near this vibrant waterway.
Why the data matters here
Understanding the flow data from the Punaluu Stream, as monitored by the U.S. Geological Survey, is crucial for local stakeholders—whether they're farmers, residents, or businesses. The stream's discharge measurements inform decision-making regarding flood risks and water management during torrential rains.
Today's data from the Punaluu Stream shows its level compared to the historical median for this date, based on records that span over 50 years. This context is critical; by comparing today's reading with the median, we get a clearer picture of whether current conditions are typical or indicative of a significant weather event. This level of insight helps ensure that those relying on Punaluu Stream remain informed and prepared for the ever-shifting dynamics of the island’s hydrology.
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.
