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 Manoa Stream at Woodlawn Drive, Oahu
Manoa Stream - A dynamic river shaped by tropical rainfall.
Manoa Stream flows through the lush landscapes of Oahu, Hawaii. This river, located at Woodlawn Drive, is part of a unique hydrographic context dominated by tropical rainfall patterns that lead to rapid changes in water levels. Surrounded by the rich flora and fauna of the island, Manoa Stream showcases the vibrant ecosystems that thrive in these conditions.
The watershed context
Manoa Stream is situated within the Oahu watershed, draining an area of approximately 4.3 square miles above the station. This relatively small drainage basin can experience significant fluctuations in flow due to its steep terrain and the localized tropical showers that frequently sweep across the island. Such rainfall-driven hydrology typically leads to flash floods, often rising dramatically in a short span of time, as influenced by trade-wind and Kona storms that can hit the region.
Its neighboring peers include Heeia Stream at Haiku Plantations Drive, Helemano 6 Reservoir, and Kalihi Stream near Honolulu, creating a network of waterways that contribute to the diverse hydrology of Oahu. Each of these streams is subject to similar conditions, reflecting the island's dynamic water systems.
Why the data matters here
Understanding water levels in Manoa Stream is crucial, especially given its propensity for sudden floods. The USGS station at Woodlawn Drive not only captures elevation readings but also monitors discharge, providing a comprehensive picture of the stream’s behavior. For those engaged in recreational activities or living in the vicinity, being aware of these fluctuations is vital for safety and planning.
Today's reading, which we will compare to the median for this calendar day over the past 15 years, gives essential insights into the current hydrological situation. Tracking how the water level trends against historical data allows stakeholders to better understand unusual behaviors in the stream and anticipate potential flood events. This data, collected by the USGS, emphasizes the importance of regular monitoring in regions prone to unpredictable storm patterns and rapid changes.
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.
