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 Ku Tree Reservoir near Wahiawa, Oahu
Ku Tree Reservoir - A key water body on the island of Oahu.
Located near Wahiawa, the Ku Tree Reservoir serves as an essential water resource in the diverse landscape of Oahu. This reservoir plays a significant role in the hydrology of the region, influenced by Hawaii's distinct tropical climate and the patterns that govern rainfall across the islands.
The watershed context
The Ku Tree Reservoir is situated within the Oahu watershed, encompassing a drainage area of roughly 0.8 square miles above the station. This small basin highlights the rapid response of the island's water systems, which can experience significant fluctuations in water levels due to intense rainfall events. Oahu's tropical island hydrology is characterized by rainfall-driven flash floods that can occur in steep short basins, rising dramatically within a matter of minutes to hours. The island is prone to the effects of trade winds and Kona storms, which can contribute to these sudden increases in water levels.
Nearby water bodies include Heeia Stream at Haiku Plantations Drive, Helemano 6 Reservoir, and the Kahaluu Stream, all part of the intricate network of waterways that flow across the island. Each of these peers contributes to the unique water dynamics of the region, as they respond to similar climatic conditions.
Why the data matters here
Monitoring the status of the Ku Tree Reservoir is vital for understanding water availability and management in Oahu. Today’s reading from the U.S. Geological Survey (USGS) station reveals how the reservoir's current level compares to historical data. This comparison against the median level for this calendar day over the past 18 years provides essential context. Such information is more insightful than raw elevation figures alone, as it allows stakeholders to grasp the broader trends and variations that may influence water resource planning, conservation strategies, and response measures for 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.
