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 Weoweopilau Stream at Highway 50 bridge, Kauai
Weoweopilau Stream - A small river with rapid response to rainfall.
Weoweopilau Stream meanders gently beneath the Highway 50 bridge in Kauai, Hawaii. This modest river, with a watershed area of roughly 0.5 square miles, exemplifies the unique rainfall-driven hydrology of the tropical island. With little warning, heavy rainfall can cause it to rise dramatically, showcasing Kauai's vibrant yet precarious hydrological character.
The watershed context
The Weoweopilau Stream flows through a steep and short basin, typical of Kauai's mountainous terrain. Rainfall events here can lead to swift flash flooding, as the watershed’s quick response to precipitation is underscored by steep topography. Driven largely by trade winds and the occasional Kona storm, the landscape can transform in minutes to hours, highlighting the volatility of water levels in this region.
Nearby, the stream connects with other waters such as the East Branch of the North Fork Wailua River and the Hanalei River, creating a network of waterways that contribute to Kauai’s rich ecological tapestry. Each of these streams and rivers experiences similar rapid changes in flow due to the island's similar climatic conditions, making the ability to monitor water levels essential for residents and visitors alike.
Why the data matters here
Monitoring the Weoweopilau Stream is particularly crucial given its response to rainfall. While direct discharge measurements are not available, the Water Survey of Canada (WSC) provides valuable elevation data. Today's reading is compared against the median for this calendar day over the past year of record-keeping. This is important for understanding trends in the river's behavior, as it helps indicate how current conditions compare to typical water levels, which is more informative than raw elevation alone. By analyzing this data, residents can better prepare for potential flooding and plan activities around the waterway accordingly.
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.
