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 Ukumehame Gulch near Olowalu, Maui
Ukumehame Gulch - a vibrant stream shaped by rainfall.
The Ukumehame Gulch near Olowalu, Maui, thrives within a unique rainfall-driven hydrology typical of tropical islands. This river channel reflects an intricate relationship between the frequent rainstorms and the steep terrain of its watershed, creating a system that can rise dramatically within minutes to hours. As trade winds and occasional Kona storms sweep through, they can deliver intense downpours, leading to rapid water level rises that characterize the gulch.
The watershed context
Draining a catchment area of roughly 3.7 square miles, Ukumehame Gulch is part of the diverse Maui watershed, which includes various streams such as Haipuaena Stream and Hanawi Stream. These water bodies share the common attributes of steep gradients and a hydrology highly responsive to rainfall events. As a tropical locale, this area does not experience a snowmelt season; instead, it relies entirely on seasonal rains, which shape the conditions and flow patterns throughout the year.
Why the data matters here
Today’s reading from the USGS station at Ukumehame Gulch provides valuable insight into localized flood risks, especially critical during the rainy season. Understanding current water levels in comparison to historical averages for this calendar day—based on more than eight years of recorded data—enables residents and visitors to anticipate conditions that could lead to flash flooding. This proactive approach to water monitoring plays an essential role in ensuring safety and preparedness in the dynamic environment surrounding Ukumehame Gulch.
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.
