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 S Waiehu Str US of ditch at alt. 315 ft, Maui
S Waiehu Stream - A dynamic waterway on Maui’s slopes.
S Waiehu Stream runs just south of a ditch at an elevation of 315 feet in the rain-soaked region of Maui, Hawaii. This river is one of the many waterways in Maui that come alive during heavy rain events, showcasing the island's tropical hydrology. The rapidly changing flow of this stream is a response to the island's unique weather patterns, where rainfall can lead to significant and swift increases in water levels.
The watershed context
Draining roughly 1.5 square miles (or about 4 square kilometers) above the S Waiehu Stream gauge, this area is characterized by steep basins that lead to quick runoff during rainstorms. As a tropical island, Maui experiences rainfall-driven flash floods influenced by trade winds and Kona storms. These short and intense rain events can cause the stream to rise dramatically, making it essential for local residents and businesses to monitor water levels for both safety and resource management.
Nearby, S Waiehu Stream is connected to other significant streams on the island, including Haipuaena Stream above Spreckels Ditch and Hanawi Stream near Nahiku. These adjacent waterways collectively contribute to Maui's rich hydrological network that supports both the local ecosystem and human activities across the island.
Why the data matters here
Today's reading from the S Waiehu Stream gauge, managed by the U.S. Geological Survey (USGS), provides vital information for understanding current conditions. Keeping track of stream levels against the median for this calendar day, based on three years of historical data, helps contextualize how today’s water level stands relative to typical fluctuations for this time of year. Monitoring these levels is not just about understanding water flow; it's crucial for predicting flash floods and ensuring the safety of the local community.
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.
